Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Presentation	Overview and Basis of Presentation Description of Business Okta, Inc. (the “Company”) is the leading independent identity provider. The Okta Identity Cloud enables the Company’s customers to securely connect the right people to the right technologies and services at the right time. The Company was incorporated in January 2009 as Saasure Inc., a California corporation, and was later reincorporated in April 2010 under the name Okta, Inc. as a Delaware corporation. The Company is headquartered in San Francisco, California. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of January 31, 2022, included herein, was derived from the audited financial statements as of that date. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the results of operations for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending January 31, 2023 or any future period. The Company’s fiscal year ends on January 31. References to fiscal 2023, for example, refer to the fiscal year ending January 31, 2023. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 7, 2022. Certain reclassifications of components of prior period operating and investing cash flows have been made in the condensed consolidated statements of cash flows to conform to the current period presentation. These reclassifications had no impact on total operating and investing cash flows as previously reported. Use of Estimates

Accounting Policies [Abstract]
Accounting Standards and Significant Accounting Policies	Accounting Standards and Significant Accounting Policies Significant Accounting Policies The Company’s significant accounting policies are discussed in “Note 2. Summary of Significant Accounting Policies” in Item 8. Financial Statements and Supplementary Data of its Form 10-K for the fiscal year ended January 31, 2022. The Company no longer considers the accounting policy for its convertible senior notes to be a significant accounting policy due to the adoption of Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2020-06 effective February 1, 2022, which simplified the accounting for convertible instruments. There have been no other significant changes to the Company’s significant accounting policies for the six months ended July 31, 2022. Recently Adopted Accounting Pronouncements ASU No. 2020-06 In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes from GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share, which is consistent with the Company’s accounting treatment prior to the adoption of ASU 2020-06. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company adopted ASU 2020-06 effective February 1, 2022, using the modified retrospective method. The Company recognized a cumulative effect of initially applying the ASU as an adjustment to the February 1, 2022 opening balance of accumulated deficit. Due to the elimination of the equity conversion component of the Company’s convertible senior notes outstanding as of February 1, 2022, additional paid-in capital was reduced. The elimination of the equity conversion component had the effect of increasing the Company’s net debt balance. The reduction of other liabilities is related to changes to the Company’s deferred tax liabilities. The prior period condensed consolidated financial statements have not been retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods. The adoption of ASU 2020-06 resulted in the following changes to the Company’s February 1, 2022 condensed consolidated balance sheet (in thousands): Balance at Adjustments from Adoption of ASU 2020-06 Balance at Liabilities Convertible senior notes, net $ 16,194 $ 927 $ 17,121 Convertible senior notes, net, noncurrent 1,815,714 371,527 2,187,241 Other liabilities, noncurrent 31,775 (866) 30,909 Stockholders’ equity Additional paid-in capital 7,749,716 (527,444) 7,222,272 Accumulated deficit (1,815,867) 155,856 (1,660,011) The impact of adoption on the condensed consolidated statements of operations for the three and six months ended July 31, 2022 was to decrease net interest expense by approximately $21.0 million and $41.8 million, respectively. This had the effect of decreasing basic and diluted net loss per share for the three and six months ended July 31, 2022 by $0.13 and $0.27, respectively. ASU No. 2021-08 In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires entities to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC Topic 606, Revenue from Contracts with Customers, primarily in order to align the recognition of a contract liability with the definition of a performance obligation. The ASU is effective for interim and annual periods beginning after December 15, 2022, on a prospective basis, with early adoption permitted. The Company adopted this standard effective February 1, 2022 on a prospective basis. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. ASU No. 2021-04 In May 2021, the FASB issued ASU No. 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. The ASU addresses the previous lack of specific guidance in the accounting standards codification related to modifications or exchanges of freestanding equity-classified written call options (such as warrants) by specifying the accounting for various modification scenarios. The ASU is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted for any periods after issuance to be applied as of the beginning of the fiscal year that includes the interim period. The Company adopted this standard effective February 1, 2022 on a prospective basis. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements.

Total consideration transferred for Auth0 was $5,671.0 million, including approximately 19.2 million shares of common stock valued at $5,175.6 million, cash of $257.0 million, and assumed outstanding equity awards with vested fair value of $238.4 million. Cash consideration of $3.8 million and approximately 1.1 million shares valued at $294.6 million were held back as partial security for post-closing true-up adjustments as well as any indemnification claims made within one year of the acquisition date. The consideration held back was paid in full during the six months ended July 31, 2022. The Company incurred $29.0 million of acquisition-related costs, which were recorded as general and administrative expenses in its condensed consolidated statement of operations for the six months ended July 31, 2021. The transaction was accounted for as a business combination.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures its financial assets at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure as follows: Level 1—Valuations based on observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2—Valuations based on other inputs that are directly or indirectly observable in the marketplace. Level 3—Valuations based on unobservable inputs that are supported by little or no market activity. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents information about the Company’s financial assets that were measured at fair value on a recurring basis using the above input categories (in thousands): As of July 31, 2022 Level 1 Level 2 Level 3 Total (unaudited) Assets: Cash equivalents: Money market funds $ 78,012 $ — $ — $ 78,012 Total cash equivalents 78,012 — — 78,012 Short-term investments: U.S. treasury securities — 1,995,840 — 1,995,840 Corporate debt securities — 265,116 — 265,116 Total short-term investments — 2,260,956 — 2,260,956 Total cash equivalents and short-term investments $ 78,012 $ 2,260,956 $ — $ 2,338,968 As of January 31, 2022 Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 152,223 $ — $ — $ 152,223 Total cash equivalents 152,223 — — 152,223 Short-term investments: U.S. treasury securities — 1,912,188 — 1,912,188 Corporate debt securities — 329,469 — 329,469 Total short-term investments — 2,241,657 — 2,241,657 Total cash equivalents and short-term investments $ 152,223 $ 2,241,657 $ — $ 2,393,880 The carrying amounts of certain financial instruments, including cash held in banks, accounts receivable and accounts payable, approximate fair value due to their short-term maturities and are excluded from the fair value table above. Fair Value Measurements of Other Financial Instruments The following table presents the principal amounts and estimated fair values of the Company’s financial instruments that are not recorded at fair value on the condensed consolidated balance sheets (in thousands): As of July 31, 2022 Principal Amount Estimated Fair Value (unaudited) 2023 convertible senior notes $ 5,226 $ 10,620 2025 convertible senior notes 1,059,997 989,215 2026 convertible senior notes 1,150,000 985,915 The 2023 convertible senior notes (“2023 Notes”), the 2025 convertible senior notes (“2025 Notes”), and the 2026 convertible senior notes (“2026 Notes”, and together with the 2023 Notes and 2025 Notes, the “Notes”) are recorded at face value less unamortized debt issuance costs (See Note 9 for additional details). The estimated fair values of the Notes, which are Level 2 financial instruments, were determined based on the quoted bid prices of the Notes in an over-the-counter market on the last trading day of the reporting period.

The 2023 Notes mature on February 15, 2023 unless earlier repurchased or converted. The Company may not redeem the 2023 Notes prior to maturity. The terms of the 2023 Notes are governed by an Indenture by and between the Company and Wilmington Trust, National Association, as Trustee (the “2023 Indenture”). Upon conversion, the 2023 Notes may be settled in cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company’s election. The 2023 Notes are convertible at an initial conversion rate of 20.6795 shares of Class A common stock per $1,000 principal amount of the 2023 Notes, which is equal to an initial conversion price of approximately $48.36 per share of Class A common stock, subject to adjustment under certain circumstances in accordance with the terms of the 2023 Indenture.

The Note Hedges will expire in 2023, if not exercised earlier. The Note Hedges are intended to offset potential dilution to the Company’s Class A common stock and/or offset the potential cash payments that the Company could be required to make in excess of the principal amount upon any conversion of the 2023 Notes under certain circumstances. The Note Hedges are separate transactions and are not part of the terms of the 2023 Notes. During the three months ended July 31, 2022, the Company net-share-settled Note Hedges corresponding to approximately $10.0 million principal amount of 2023 Notes and received approximately 0.1 million shares of Class A common stock and an immaterial cash payment.

If the Warrants are not exercised on their exercise dates, they will expire. If the market value per share of the Company’s Class A common stock exceeds the applicable exercise price of the Warrants, the Warrants could have a dilutive effect on the Company’s Class A common stock unless, subject to the terms of the Warrants, the Company elects to cash settle the Warrants. The Warrants are separate transactions and are not part of the terms of the 2023 Notes or the Note Hedges. As of July 31, 2022, Warrants to acquire up to approximately 1.0 million shares (subject to adjustment) remained outstanding. 2025 Convertible Senior Notes The 2025 Notes are senior, unsecured obligations of the Company, and bear interest at a fixed rate of 0.125% per year.

The Company may redeem for cash all or any portion of the 2025 Notes, at its option, on or after September 6, 2022, if the last reported sale price of the Company’s Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on and including the trading day preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2025 Notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date.

(2) Included in the January 31, 2022 condensed consolidated balance sheet within Additional paid-in capital. 2025 Capped Calls In connection with the pricing of the 2025 Notes, the Company entered into capped call transactions with respect to its Class A common stock (the “2025 Capped Calls”). The 2025 Capped Calls are purchased call options that give the Company the option to purchase approximately 5.6 million shares, subject to anti-dilution adjustments substantially identical to those in the 2025 Notes, of its Class A common stock for approximately $188.71 per share (subject to adjustment), corresponding to the approximate initial conversion price of the 2025 Notes, exercisable upon conversion of the 2025 Notes. The 2025 Capped Calls have initial cap prices of $255.88 per share (subject to adjustment) and will expire in 2025, if not exercised earlier. The 2025 Capped Calls are intended to offset potential dilution to the Company’s Class A common stock and/or offset the potential cash payments that the Company could be required to make in excess of the principal amount upon any conversion of the 2025 Notes under certain circumstances. The 2025 Capped Calls are separate transactions and are not part of the terms of the 2025 Notes. 2026 Convertible Senior Notes The 2026 Notes are senior, unsecured obligations of the Company, and bear interest at a fixed rate of 0.375% per year. Interest is payable in cash semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2020. The 2026 Notes mature on June 15, 2026 unless earlier redeemed, repurchased or converted. The terms of the 2026 Notes are governed by an Indenture by and between the Company and Wilmington Trust, National Association, as Trustee (the “2026 Indenture”). Upon conversion, the 2026 Notes may be settled in cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company’s election. The 2026 Notes are convertible at an initial conversion rate of 4.1912 shares of Class A common stock per $1,000 principal amount of the 2026 Notes, which is equal to an initial conversion price of approximately $238.60 per share of Class A common stock, subject to adjustment under certain circumstances in accordance with the terms of the Indenture. Prior to the close of business on the business day immediately preceding March 15, 2026, holders of the 2026 Notes may convert all or a portion of their 2026 Notes only in multiples of $1,000 principal amount, under the following circumstances: • during any fiscal quarter commencing after the fiscal quarter ending on October 31, 2020 (and only during such fiscal quarter), if the last reported sale price of the Company’s Class A common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price of the 2026 Notes on each applicable trading day; • during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the 2026 Notes for each trading day of that five consecutive trading day period was less than 98% of the product of the last reported sale price of the Company’s Class A common stock and the conversion rate on such trading day; • if the Company calls the notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or • upon the occurrence of specified corporate events, as described in the 2026 Indenture. On or after March 15, 2026 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their 2026 Notes regardless of the foregoing circumstances. During the three months ended July 31, 2022, the conditions allowing holders of the 2026 Notes to convert were not met, and as a result, the 2026 Notes were classified as noncurrent liabilities as of July 31, 2022. The Company may redeem for cash all or any portion of the 2026 Notes, at its option, on or after June 20, 2023, if the last reported sale price of the Company’s Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on and including the trading day preceding the date on which the Company provides notice of redemption price equal to 100% of the principal amount of the notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. During the three months ended July 31, 2022, the Company did not redeem any of the 2026 Notes. Holders of the 2026 Notes who convert their 2026 Notes in connection with certain corporate events that constitute a make-whole fundamental change (as defined in the 2026 Indenture) or in connection with the Company’s issuance of a redemption notice are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a corporate event that constitutes a fundamental change (as defined in the Indenture), holders of the 2026 Notes may require the Company to repurchase all or a portion of their 2026 Notes at a price equal to 100% of the principal amount of the 2026 Notes being repurchased, plus any accrued and unpaid interest. As of July 31, 2022, the effective interest rate on the 2026 Notes was 0.60%. As of July 31, 2021, prior to the adoption of ASU 2020-06, the effective interest rate on the liability component of the 2026 Notes was 5.75%.

The 2026 Capped Calls are purchased call options that give the Company the option to purchase approximately 4.8 million shares, subject to anti-dilution adjustments substantially identical to those in the 2026 Notes, of its Class A common stock for approximately $238.60 per share (subject to adjustment), corresponding to the approximate initial conversion price of the 2026 Notes, exercisable upon conversion of the 2026 Notes. The 2026 Capped Calls have initial cap prices of $360.14 per share (subject to adjustment) and will expire in 2026, if not exercised earlier. The 2026 Capped Calls are intended to offset potential dilution to the Company’s Class A common stock and/or offset the potential cash payments that the Company could be required to make in excess of the principal amount upon any conversion of the 2026 Notes under certain circumstances. The 2026 Capped Calls are separate transactions and are not part of the terms of the 2026 Notes.

Employee Incentive Plans	Employee Incentive Plans The Company’s equity incentive plans provide for granting stock options, restricted stock units (“RSUs”), restricted stock awards to employees, consultants, officers and directors and restricted stock units with market-based vesting conditions to certain executives. In addition, the Company offers an Employee Stock Purchase Plan (“ESPP”) to eligible employees. Stock-based compensation expense was recorded in the following cost and expense categories in the Company’s condensed consolidated statements of operations (in thousands): Three Months Ended Six Months Ended 2022 2021 2022 2021 (unaudited) Cost of revenue Subscription $ 17,778 $ 13,138 $ 34,403 $ 20,388 Professional services and other 3,816 3,161 7,453 5,503 Research and development 70,078 53,332 139,122 73,425 Sales and marketing 38,982 41,288 78,784 62,354 General and administrative 40,525 76,795 80,940 90,156 Total $ 171,179 $ 187,714 $ 340,702 $ 251,826 Equity Incentive Plans The Company has two equity incentive plans: the 2009 Stock Plan and the 2017 Equity Incentive Plan (“2017 Plan”). In addition, the Company assumed Auth0 equity incentive plans. All shares that remain available for future grants are under the 2017 Plan. As of July 31, 2022, options to purchase 1,968,404 shares of Class A common stock and 5,295,955 shares of Class B common stock remained outstanding.

Market-based Restricted Stock Units In March 2022, the Company granted market-based RSUs (“PSUs”) to certain members of management. The target number of PSUs granted was 58,150. One-third of these PSUs vest over each of a one-, two- and three-year performance period, each starting on February 1, 2022. The number of shares that can be earned ranges from 0% to 200% of the target number of shares based on the relative performance of the per share price of the Company’s common stock as compared to the Nasdaq Composite Index over the respective performance periods and subject to continuous employment through the vesting dates. The $244.73 grant date fair value per target PSU was determined using a Monte Carlo simulation approach. Compensation expense for awards with market conditions is recognized over the service period using the accelerated attribution method and is not reversed if the market condition is not met. Restricted Stock Awards Issued in Connection with Business Combinations In fiscal year 2022, the Company entered into revesting agreements with the founders of the acquired businesses pursuant to which 1,269,008 restricted shares of Okta’s Class A common stock with a weighted-average fair value per share of $268.98 issued as of the respective closing dates will vest over 3 years. In connection with the business combinations, as of July 31, 2022, there was $200.8 million of unrecognized stock-based compensation expense related to unvested restricted shares, which is being recognized over a weighted-average period of 1.8 years based on vesting under the award service conditions. Employee Stock Purchase Plan The ESPP provides for 12-month offering periods beginning June 21 and December 21 of each year, and each offering period consists of up to two six-month purchase periods. The ESPP contains a reset provision under which the offering period resets if the fair market value of the Company’s common stock on the purchase date is less than the fair market value on the offering date. The Company estimated the fair value of ESPP purchase rights using a Black-Scholes option pricing model with the following assumptions: Three and Six Months Ended July 31, 2022 2021 (unaudited) Expected volatility 63%- 78% 47% - 48% Expected term (in years) 0.5 - 1.0 0.5 - 1.0 Risk-free interest rate 2.46% - 2.92% 0.06% - 0.09% Expected dividend yield — — During the three and six months ended July 31, 2022, the Company’s employees purchased 269,814 shares of its Class A common stock under the ESPP. The shares were purchased at a weighted-average purchase price of $70.27 per share, with total proceeds of $19.0 million. As of July 31, 2022, there was $20.8 million of unrecognized stock-based compensation expense related to the ESPP that is expected to be recognized over a weighted-average vesting period of 0.8 years.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and six months ended July 31, 2022, the Company recorded a tax provision of $4.2 million and $6.1 million on pretax losses of $206.3 million and $447.1 million, respectively. The effective tax rate for the three and six months ended July 31, 2022 was approximately (2.0)% and (1.4)%, respectively. The effective tax rate differs from the statutory rate primarily as a result of not recognizing the tax benefit for U.S. losses due to a full valuation allowance against U.S. deferred tax assets, the tax effect of foreign operations, and U.S. state taxes. The Tax Cuts and Jobs Act enacted on December 22, 2017 amended Internal Revenue Code Section 174 to require that specific research and experimental ("R&E") expenditures be capitalized and amortized over five years (U.S. R&E) or fifteen years (non-U.S. R&E) beginning in the Company's fiscal 2023. Although Congress has considered legislation that would defer, modify or repeal the capitalization and amortization requirement, there is no assurance the provision will be deferred, repealed or otherwise modified. If the requirement is not modified, the Company may be required to utilize some of its federal and state tax attributes and there may be increases to cash taxes or tax expense. For the three and six months ended July 31, 2021, the Company recorded a tax benefit of $7.5 million and $7.5 million on pretax losses of $284.1 million and $393.4 million, respectively. The effective tax rate for the three and six months ended July 31, 2021 was approximately 2.6% and 1.9%, respectively. The effective tax rate differs from the statutory rate primarily as a result of not recognizing deferred tax assets for U.S. losses due to a full valuation allowance against U.S. deferred tax assets, release of the valuation allowance in the United States in connection with the Auth0 acquisition, a remeasurement of deferred tax assets in connection with a tax rate change in the United Kingdom, and excess tax benefits from stock-based compensation in the United Kingdom. The tax benefit was partially offset by income tax expense in profitable foreign jurisdictions and U.S. state taxes.

Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in thousands): As of July 31, 2022 2021 (unaudited) Issued and outstanding stock options 7,264 9,077 Unvested RSUs issued and outstanding 8,648 5,302 Unvested PSUs issued and outstanding 116 — Unvested restricted stock awards issued and outstanding 859 1,231 Shares committed under the ESPP 626 227 Shares related to the 2023 Notes 108 356 Shares subject to warrants related to the issuance of the 2023 Notes 1,048 1,048 Shares related to the 2025 Notes 5,617 5,617 Shares related to the 2026 Notes 4,820 4,820 29,106 27,678 The Company uses the if-converted method for calculating any potential dilutive effect of the conversion options embedded in the Notes on diluted net income per share, if applicable. The conversion options of the 2023, 2025 and 2026 Notes are dilutive in periods of net income on a weighted-average basis using an assumed conversion date equal to the later of the beginning of the reporting period and the date of issuance of the respective Notes. The exercise rights of the Warrants will have a dilutive impact on net income per share of common stock under the treasury-stock method when the average market price per share of the Company’s Class A common stock for a given period exceeds the conversion price of $68.06 per share. During the three months ended July 31, 2022, the average price per share of the Company’s Class A common stock exceeded the exercise price of the Warrants; however, since the Company is in a net loss position, there was no dilutive effect during any period presented.

Accounting Standards and Sign_2

Accounting Standards and Significant Accounting Policies (Policies)	6 Months Ended
	Jul. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).
Principles of Consolidation	All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of January 31, 2022, included herein, was derived from the audited financial statements as of that date. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the results of operations for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending January 31, 2023 or any future period.
Fiscal Period	The Company’s fiscal year ends on January 31. References to fiscal 2023, for example, refer to the fiscal year ending January 31, 2023.
Reclassification	Certain reclassifications of components of prior period operating and investing cash flows have been made in the condensed consolidated statements of cash flows to conform to the current period presentation. These reclassifications had no impact on total operating and investing cash flows as previously reported.
Use of Estimates	The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. Actual results could vary from those estimates. The Company’s most significant estimates include the stand-alone selling price (“SSP”) for each distinct performance obligation included in customer contracts with multiple performance obligations, the determination of the period of benefit for deferred commissions, the determination of the incremental borrowing rate used for operating lease liabilities, the valuation of deferred income tax assets, the valuation of goodwill and acquired intangible assets and their useful lives and the valuation of certain equity awards assumed.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements ASU No. 2020-06 In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes from GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share, which is consistent with the Company’s accounting treatment prior to the adoption of ASU 2020-06. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company adopted ASU 2020-06 effective February 1, 2022, using the modified retrospective method. The Company recognized a cumulative effect of initially applying the ASU as an adjustment to the February 1, 2022 opening balance of accumulated deficit. Due to the elimination of the equity conversion component of the Company’s convertible senior notes outstanding as of February 1, 2022, additional paid-in capital was reduced. The elimination of the equity conversion component had the effect of increasing the Company’s net debt balance. The reduction of other liabilities is related to changes to the Company’s deferred tax liabilities. The prior period condensed consolidated financial statements have not been retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods. ASU No. 2021-08 In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires entities to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC Topic 606, Revenue from Contracts with Customers, primarily in order to align the recognition of a contract liability with the definition of a performance obligation. The ASU is effective for interim and annual periods beginning after December 15, 2022, on a prospective basis, with early adoption permitted. The Company adopted this standard effective February 1, 2022 on a prospective basis. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. ASU No. 2021-04 In May 2021, the FASB issued ASU No. 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options.
