Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of January 31, 2021 was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by GAAP for complete financial statements.

The results of operations for the three months ended April 30, 2021 are not necessarily indicative of the results to be expected for the full year ending January 31, 2022 or for any other interim period, or for any future year. The Company’s fiscal year ends on January 31. References to fiscal 2022, for example, refer to the fiscal year ended January 31, 2022.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make, on an ongoing basis, estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. The Company’s most significant estimates and judgments involve the fair value of stock awards, period of benefit for amortizing deferred contract costs, the determination of the allowance for doubtful accounts, the provision for income taxes, including the related valuation allowance and any uncertain tax positions, fair value of acquired assets and assumed liabilities, impairment of goodwill and intangible assets, the incremental borrowing rate for lease liabilities, and estimates related to our revenue recognition, such as the assessment of performance obligations in our revenue arrangements and the fair value assigned to each performance obligation, among others. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Concentrations of Risk and Significant Customers	Concentrations of Risk and Significant Customers The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, available-for-sale investments, and accounts receivable. All of the Company’s cash and cash equivalents and investments are invested in money market funds, United States (“U.S.”) Treasury securities, commercial paper, corporate debt securities, or U.S. Government agency securities that management believes to be of high credit quality.
Segment Information	Segment Information The Company manages its operations and allocates resources as one operating segment. The Company’s chief operating decision maker (“CODM”) is its chief executive officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, and allocating resources.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for all stock-based payment awards, including stock options, restricted stock units (“RSUs”), and performance stock units (“PSUs”), based on the estimated fair value of the award on the grant date. The Company estimates the fair value of stock options issued to employees on the date of grant using the Black-Scholes option pricing model, which is impacted by the estimated fair value of the Company’s common stock, as well as certain assumptions including the expected volatility over the term of the option awards, the expected term of the awards, risk-free interest rates and the expected dividend yield. Assumptions and estimates used in the determination of the fair value of stock options are as follows: Expected volatility—Expected volatility is a measure of the amount by which the stock price is expected to fluctuate. Since the Company does not have sufficient trading history for its common stock, it estimates the expected volatility of its stock options by taking the average historical volatility of a group of comparable publicly traded companies over a period equal to the expected life of the options. Expected term—The Company determines the expected term based on the average period the stock options are expected to remain outstanding, generally calculated as the midpoint of the stock options’ vesting term and contractual expiration period, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior. Risk-free rate—The Company uses the U.S. Treasury yield for its risk-free interest rate that corresponds with the expected term. Expected dividend yield—The Company utilizes a dividend yield of zero, as it does not currently issue dividends and does not expect to in the future. The Company estimates the fair value of RSUs and PSUs at our stock price on the grant date. The Company estimates the fair value of shares to be issued under the employee stock purchase plan (the “ESPP”) on the first day of the offering period using the Black-Scholes valuation model, which is impacted by the estimated fair value of the Company’s common stock, as well as certain assumptions including the expected volatility over the term of the offering period, the expected term of the awards, risk-free interest rates and the expected dividend yield. Assumptions used in the determination of the fair value of the ESPP are the same as those used in the determination of the fair value of our stock options. The Company generally recognizes compensation expense for employee stock-based payment awards on a straight-line basis over the period during which an award recipient is required to provide services in exchange for the award (generally the vesting period of the award), with the exception of PSUs which are recognized using the accelerated attribution method. The Company accounts for forfeitures as they occur. The fair value of each non-employee stock option is estimated at the date of grant using the Black-Scholes option pricing model and is not remeasured over the vesting term. Assumptions used in valuing non-employee stock options are generally consistent with those used for employee stock options with the exception that the expected term is over the contractual life.

Operating Leases	Operating Leases The Company has entered into various non-cancellable operating leases for its office spaces with lease periods expiring between fiscal 2022 and fiscal 2029. The operating lease agreements generally provide for rental payments on a graduated basis and for options to renew, which could increase future minimum lease payments if exercised. Lease right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease right-of-use assets also include any lease payments made and exclude lease incentives such as tenant improvement allowances. The operating leases typically include non-lease components such as common-area maintenance costs. The Company has elected to include non-lease components with lease payments for the purpose of calculating lease right-of-use assets and liabilities, to the extent that they are fixed. Non-lease components that are not fixed are expensed as incurred as variable lease payments. Leases with a term of one year or less are not recognized on our condensed consolidated balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term.
