Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements (“financial statements”) have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial information. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2022, included in the Company’s Annual Report on Form 10-K, filed with the SEC on February 17, 2023. The results for the interim periods are not necessarily indicative of results for the full year. The Company has changed its presentation from thousands to millions and, as a result, any necessary rounding adjustments have been made to prior period disclosed amounts. Certain immaterial amounts in prior periods have been reclassified to conform with current period presentation. In the opinion of management, these financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods.
Principles of Consolidation	Principles of Consolidation The accompanying financial statements include the accounts of the Company and its wholly-owned subsidiaries and variable interest entities (“VIE”) in which the Company is the primary beneficiary in accordance with consolidation accounting guidance. All intercompany transactions have been eliminated in consolidation. The Company determines, at the inception of each arrangement, whether an entity in which it has made an investment or in which it has other variable interest in is considered a VIE. The Company consolidates a VIE when it is deemed to be the primary beneficiary. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to direct the activities that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Periodically, the Company determines whether any changes in its interest or relationship with the entity impact the determination of whether the entity is still a VIE and, if so, whether the Company is the primary beneficiary. If the Company is not deemed to be the primary beneficiary in a VIE, the Company accounts for the investment or other variable interest in a VIE in accordance with applicable U.S. GAAP. As of March 31, 2023, the Company’s consolidated VIEs were not material to the financial statements.
Use of Estimates	Use of Estimates The preparation of the Company’s financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company regularly evaluates its estimates, including those related to bad debt reserves, fair value of investments, useful lives of long-lived assets and intangible assets, valuation of goodwill and intangible assets from acquisitions, contingent liabilities, insurance reserves, revenue recognition, valuation of common stock, stock-based compensation, and income and non-income taxes, among others. Actual results could differ materially from these estimates. As the impact of the uncertain macroeconomic conditions, including inflation and rising interest rates, continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require increased judgment. These estimates and assumptions may change in future periods and will be recognized in the financial statements as new events occur and additional information becomes known. To the extent the Company’s actual results differ materially from those estimates and assumptions, the Company’s future financial statements could be affected.
Short-term Investments	Short-term Investments The Company considers all highly-liquid investments with original maturities of greater than 90 days to be short-term investments. Short-term investments include time deposits, which are accounted for at amortized cost, and available-for-sale debt securities that consist of corporate debt securities, commercial paper, certificates of deposit, U.S. government and government agency debt securities (“government bonds”), and mortgage-backed and asset-backed securities. The Company determines the appropriate classification of its investments at the time of purchase. The Company determines realized gains or losses on the sale of equity and debt securities on a specific identification method. Unrealized gains and non-credit related losses on available-for-sale debt securities are reported as a component of accumulated other comprehensive income (loss) (“AOCI”) in stockholders’ equity. Realized gains and losses and impairments are reported within other expense, net in the condensed consolidated statements of operations. The assessment for impairment takes into account the severity and duration of the decline in value, adverse changes in the market or industry of the investee, the Company’s intent to sell the security, and whether it is more likely than not that it will be required to sell the security before recovery of the amortized cost basis.The Company’s equity investments with readily determinable fair values are measured at fair value on a recurring basis with changes in fair value recognized within other expense, net in the condensed consolidated statements of operations.
Derivative Instruments and Hedging	Derivative Instruments and Hedging The Company’s primary objective for holding derivative instruments is to manage foreign currency exchange rate risk. The Company enters into master netting arrangements to mitigate credit risk in derivative transactions by permitting net settlement of transactions with the same counterparty. All derivative instruments are recorded in the condensed consolidated balance sheets at fair value. The accounting treatment for derivative gains and losses is based on intended use and hedge designation. Gains and losses arising from amounts that are included in the assessment of cash flow hedge effectiveness are initially deferred in AOCI and subsequently reclassified into earnings when the hedged transaction affects earnings and in the same line item within the condensed consolidated statement of operations. The Company does not exclude any components in the assessment of hedge effectiveness for forwards and options. When it is no longer probable that a forecasted hedged transaction will occur in the initially identified time period, hedge accounting is discontinued and the Company accounts for the associated derivatives as undesignated derivative instruments. Gains and losses associated with derivatives no longer designated as hedging instruments in AOCI are recognized immediately in other expense, net, if it is probable that the forecasted hedged transaction will not occur by the end of the initially identified time period or within an additional two month period thereafter. In rare circumstances, the additional period of time may exceed two months due to extenuating circumstances related to the nature of the forecasted transaction that are outside the control or influence of the Company. Gains and losses arising from changes in the fair value of derivative instruments that are not designated as accounting hedges are recognized in the condensed consolidated statement of operations in other expenses, net. The Company presents derivative assets and liabilities at their gross fair values in the condensed consolidated balance sheets, even if they are subject to master netting arrangements with the counterparties.

The accompanying unaudited condensed consolidated financial statements (“financial statements”) have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial information. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2022, included in the Company’s Annual Report on Form 10-K, filed with the SEC on February 17, 2023. The results for the interim periods are not necessarily indicative of results for the full year. The Company has changed its presentation from thousands to millions and, as a result, any necessary rounding adjustments have been made to prior period disclosed amounts. Certain immaterial amounts in prior periods have been reclassified to conform with current period presentation.

In the opinion of management, these financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods.

Principles of Consolidation

The accompanying financial statements include the accounts of the Company and its wholly-owned subsidiaries and variable interest entities (“VIE”) in which the Company is the primary beneficiary in accordance with consolidation accounting guidance. All intercompany transactions have been eliminated in consolidation.

The Company determines, at the inception of each arrangement, whether an entity in which it has made an investment or in which it has other variable interest in is considered a VIE. The Company consolidates a VIE when it is deemed to be the primary beneficiary. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to direct the activities that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Periodically, the Company determines whether any changes in its interest or relationship with the entity impact the determination of whether the entity is still a VIE and, if so, whether the Company is the primary beneficiary. If the Company is not deemed to be the primary beneficiary in a VIE, the Company accounts for the investment or other variable interest in a VIE in accordance with applicable U.S. GAAP. As of March 31, 2023, the Company’s consolidated VIEs were not material to the financial statements.

Use of Estimates

The preparation of the Company’s financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company regularly evaluates its estimates, including those related to bad debt reserves, fair value of investments, useful lives of long-lived assets and intangible assets, valuation of goodwill and intangible assets from acquisitions, contingent liabilities, insurance reserves, revenue recognition, valuation of common stock, stock-based compensation, and income and non-income taxes, among others.
