Summary of Significant Accounting Policies (Notes)	Jun. 30, 2024
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Basis of presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial reporting and applicable quarterly reporting regulations of the Securities and Exchange Commission ("SEC"). In management's opinion, the accompanying interim unaudited condensed consolidated financial statements include all adjustments necessary for a fair statement of the financial position of the Company as of June 30, 2024, the results of operations for the three and six months ended June 30, 2024 and 2023, cash flows for the six months ended June 30, 2024 and 2023, and stockholders' (deficit) equity for the three and six months ended June 30, 2024 and 2023. Certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2023 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP. Changes in accounting policies There have been no material changes in the Company’s significant accounting policies and their application as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 . Fair value measurement The Company's financial assets that are included in cash and cash equivalents and that are measured at fair value on a recurring basis consisted of $124.7 million and $153.2 million at June 30, 2024 and December 31, 2023, respectively, and were invested in treasury, money market funds and interest-bearing deposits in banks. The fair value of those investments is determined based on quoted market prices, which represents level 1 in the fair value hierarchy as defined by ASC 820. See Note 8 for the fair value measurement of the convertible notes. Deferred costs Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are deferred and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. The Company determined the period of benefit by taking into consideration its customer contracts, expected renewals of those customer contracts (as the Company currently does not pay an incremental sales commission for renewals), the Company's technology and other factors. The Company also defers amounts earned by employees other than sales representatives who earn incentive payments under compensation plans also tied to the value of customer contracts acquired. Deferred costs were $14.6 million and $15.1 million as of June 30, 2024 and December 31, 2023, respectively. Amortization expense for the deferred costs was $1.1 million and $1.5 million for the three months ended June 30, 2024 and 2023, respectively, and $2.4 million and $2.9 million for the six months ended June 30, 2024 and 2023, respectively. Amortization of deferred costs is included in selling and marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive loss. Recently issued accounting pronouncements not yet adopted In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and other segment items on an annual and interim basis. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The ASU is to be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures which expands disclosures in an entity’s income tax rate reconciliation table and disclosures regarding income taxes paid by jurisdiction. The new standard is effective for annual periods beginning after December 15, 2024, and early adoption is permitted. The new standard is to be applied on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and related disclosures. There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2024, as compared to the recent accounting pronouncements described in the Company's Annual Report, that are of significance or potential significance to the Company.

Noncash Share-based Compensation [Abstract]
Noncash Share-based Compensation	Noncash Share-based Compensation The Company's 2017 Equity Incentive Plan (as amended and restated, the "2017 Stock Plan") had an aggregate authorized limit of 7,650,000 shares for issuance. In May 2023, the Company's stockholders approved an amendment to the 2017 Stock Plan increasing the aggregate amount of shares available for issuance to 10,550,000. As of June 30, 2024, 3,254,841 shares remain available for issuance under the 2017 Stock Plan. The following table presents the number of shares or units outstanding for each award type as of June 30, 2024 and December 31, 2023 (in thousands): Award type June 30, 2024 December 31, 2023 Restricted stock units (time-based) 2,969 2,767 Market stock units 439 358 During the three months ended June 30, 2024, the Company granted 137,531 RS Us (time-based) with a weighted average grant-date fair value of $32.43 per share. During the six months ended June 30, 2024, the Company granted 1,333,618 RSUs (time-based) with a weighted average grant-date fair value of $35.35 per share. The Company also granted 47,789 MSUs with a weighted average grant-date fair value of $36.87 to certain executive employees during the three months ended June 30, 2024, and 179,681 MSUs with a weighted average grant-date fair value of $39.95 to certain executive employees during the six months ended June 30, 2024. These MSUs vest on January 31, 2027, and the actual number of MSUs that will be eligible to vest is based on the total stockholder return of the Company relative to the total stockholder return of the Index over the performance period, as defined by each award's plan documents or individual award agreements. The maximum number of shares issuable upon vesting is 200% of the MSUs initially granted. The Company estimates the fair value of MSUs on the date of grant using a Monte Carlo simulation model. The weighted average assumptions used to value the MSUs granted during the three and six months ended June 30, 2024 were as follows: Three Months Ended June 30, 2024 Six Months Ended June 30, 2024 Volatility 52.06 % 51.24 % Risk-free interest rate 4.82 % 4.14 % Expected award life in years 2.70 2.90 Dividend yield — % — % Share-based compensation expense is allocated to expense categories in the unaudited condensed consolidated statements of comprehensive loss. The following table summarizes share-based compensation expense included in the Company's unaudited condensed consolidated statements of comprehensive loss for the three and six months ended June 30, 2024 and 2023 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Share-based compensation: Cost of revenue $ 1,151 $ 985 $ 2,219 $ 1,817 Operating expenses: Selling and marketing 2,437 3,103 6,065 6,031 Research and development 2,114 2,673 5,645 5,023 General and administrative 4,546 3,991 9,019 7,785 Total included in operating expenses 9,097 9,767 20,729 18,839 Total share-based compensation expense $ 10,248 $ 10,752 $ 22,948 $ 20,656 At June 30, 2024, the Company had an estimated $91.6 million of total unrecognized compensation costs related to share-based compensation arrangements. These costs will be recognized over a weighted average period o f 2.8 years. The Company's Employee Stock Purchase Plan (as amended, the "ESPP") permits eligible employees to purchase Company shares on an after-tax basis in an amount between 1% and 10% of their annual pay: (i) on June 30 of each year at a 15% discount of the fair market value of the Company's common stock on January 1 or June 30, whichever is lower, and (ii) on Dec ember 31 of each year at a 15% discount of the fair market value of the Company's common stock on July 1 or December 31, whichever is lower. An employee may not purchase more than $5,000 in either of the six-month measurement periods described above or more than $10,000 annually. In May 2021, the Company's stockholders approved an amendment to the ESPP increasing the aggregate amount of shares available for issuance under the ESPP to 1,000,000. During the three and six months ended June 30, 2024, the Company issued zero and 40,408 shares under the ESPP, respectively.

Long-term Debt [Text Block]	Convertible Senior Notes The following is a summary of the Company's convertible senior notes as of June 30, 2024 (in thousands): Date of Issuance Unpaid Principal Balance Contractual Interest Rates 1% Convertible Notes due in 2024 ("2024 Notes") May 2019 $ — 1% 2.25% Convertible Notes due in 2027 ("2027 Notes") September 2020 and October 2023 $ 266,816 2.25% Total Notes $ 266,816 The 2027 and 2024 Notes (collectively, the "Notes") are general unsecured obligations and rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Notes, rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated, are effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and are structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries (including trade payables but excluding intercompany obligations owed to the Company or its subsidiaries). The 2027 Notes mature on September 15, 2027, unless redeemed or converted in accordance with their terms prior to such date. The 2024 Notes matured on May 15, 2024 and the Company settled the outstanding principal balance of $21.7 million during the quarter ended June 30, 2024. Interest related to the 2027 Notes is payable semi-annually in arrears in cash on March 15 and September 15 of each year, beginning on March 15, 2021. Interest related to the 2024 Notes was payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2019. Each $1,000 of principal of the 2027 Notes will initially be convertible into 23.9137 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $41.82 per share and is subject to adjustment upon the occurrence of certain specified events. Each $1,000 of principal of the 2024 Notes was initially to be convertible into 15.1394 shares of the Company’s common stock, which was equivalent to an initial conversion price of approximately $66.05 per share and was subject to adjustment upon the occurrence of certain specified events. On August 23, 2023, the Company entered into legally binding exchange agreements with a limited number of existing holders of the 2024 Notes to exchange approximately $122.0 million aggregate principal amount of the existing 2024 Notes for a principal amount of the 2027 Notes at an exchange ratio to be determined based on the daily volume-weighted average trading price of the Company’s common stock over a thirty-day trading period beginning August 24, 2023 (such exchange transactions, the “Exchange”). On October 10, 2023, the Company settled the exchange agreements for the exchange of $122.0 million aggregate principal amount of its outstanding 2024 Notes for newly issued $116.8 million aggregate principal amount of its outstanding 2027 Notes. Following the settlement of the Exchange, $21.7 million in aggregate principal amount of the 2024 Notes and $266.8 million in aggregate principal amount of the 2027 Notes remained outstanding with terms unchanged. The 2027 Notes issued in the Exchange constitute a further issuance of, and form a single series and will be fungible with, the existing 2027 Notes. As of June 30, 2024, the 2027 Notes are not yet convertible and their remaining term is approximatel y 39 months. As of June 30, 2024 and December 31, 2023, the fair value of the outstanding principal amount of the Notes in the aggregate was $256.7 million and $320.5 million, respectively. The estimated fair value was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the Company's stock price and interest rates, which represents level 2 in the fair value hierarchy. The Notes consist of the following (in thousands): June 30, 2024 December 31, 2023 Principal $ 266,816 $ 288,529 Debt premium, net of amortization 8,427 9,776 Debt issuance costs, net of amortization (3,690) (4,313) Net carrying amount $ 271,553 $ 293,992 The following table sets forth total interest expense recognized related to the Notes (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Coupon interest $ 1,520 $ 1,203 $ 3,075 $ 2,406 Amortization of debt issuance costs 301 373 624 746 Amortization of debt premium (673) — (1,349) — Total $ 1,148 $ 1,576 $ 2,350 $ 3,152 Capped call transactions In September 2020 and in May 2019, in connection with the offering of the 2027 and 2024 Notes, respectively, the Company entered into privately negotiated capped call transactions (collectively, the "Capped Call") with certain option counterparties. The Capped Call transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock initially underlying the Notes, at a strike price that corresponds to the initial conversion price of the Notes, also subject to adjustment, and are exercisable upon conversion of the Notes. The Capped Call transactions are intended to reduce potential dilution to the Company’s common stock and/or offset any cash payments the Company will be required to make in excess of the principal amounts upon any conversion of the Notes, and to effectively increase the overall conversion price of the 2027 Notes from $41.82 to $78.90 per share, and for the 2024 Notes from $66.05 to $101.62 per share. As the Capped Call transactions meet certain accounting criteria, they are recorded in stockholders’ (deficit) equity and are not accounted for as derivatives. The cost of the Capped Call was $25.3 million and $16.4 million for the 2027 and 2024 Notes, respectively, and was recorded as part of additional paid-in capital. On May 15, 2024, the 2024 Notes matured and the Capped Call associated with the 2024 Notes expired unexercised. The expiration of the 2024 Notes Capped Call did not have an impact on the unaudited condensed consolidated financial statements. In August 2023, in connection with the Exchange, the Company entered into additional capped call transactions (the “Additional Capped Call”) with certain option counterparties. The Company agreed to pay a premium to the option counterparties for the Additional Capped Call for an amount to be determined based on the volume-weighted average trading price of the Company’s common stock over a thirty-day reference period beginning August 24, 2023. The conversion price of the Additional Capped Call is the same as the 2027 Notes Capped Call above. Initial funding of the Additional Capped Call occurred in the third quarter of 2023. The Additional Capped Call had a deferred premium component indexed to the Company's stock price and required to be settled in cash, and therefore the Additional Capped Call was a derivative instrument that, at inception, did not meet the qualifications for equity classification. On October 10, 2023, the Company settled the deferred premium on the Additional Capped Call resulting in a final value of $22.2 million . Once the deferred premium was settled, the instrument met the requirements for equity classification and the Company reclassified the Additional Capped Call to additional paid-in capital.

Fair value measurement	Fair value measurement
Revenue Recognition, Customer Acquisitions [Policy Text Block]	Deferred costs Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are deferred and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. The Company determined the period of benefit by taking into consideration its customer contracts, expected renewals of those customer contracts (as the Company currently does not pay an incremental sales commission for renewals), the Company's technology and other factors. The Company also defers amounts earned by employees other than sales representatives who earn incentive payments under compensation plans also tied to the value of customer contracts acquired. Deferred costs were $14.6 million and $15.1 million as of June 30, 2024 and December 31, 2023, respectively. Amortization expense for the deferred costs was $1.1 million and $1.5 million for the three months ended June 30, 2024 and 2023, respectively, and $2.4 million and $2.9 million for the six months ended June 30, 2024 and 2023, respectively.
