Onramp

Create an onramp order

Changed on Oct 6, 2026

Create a new Onramp order or get a quote for an Onramp order. Either paymentAmount or purchaseAmount must be provided.

This API supports two modes:

Headless mode (standard): returns a seamless Apple Pay or Google Pay button that you integrate directly into your app. Your app collects and verifies the user's contact details before calling this endpoint — phoneNumber, email, phoneNumberVerifiedAt, and agreementAcceptedAt are required and enforced server-side.

Embedded mode: returns a webview that collects and verifies the user's contact and identity information, then shows the payment screen. Omit both phoneNumber and email from the request to select this mode. Embedded mode requires account enablement; contact the Onramp team for access.

Read more about the difference between the two modes in the Headless Onramp overview.

This API supports the GUEST_CHECKOUT_APPLE_PAY and GUEST_CHECKOUT_GOOGLE_PAY payment methods.

For detailed integration instructions and to get access to this API, refer to the Guest Checkout Onramp API docs.

Request

Base URL: https://api.cdp.coinbase.com/platform
URL: https://api.cdp.coinbase.com/platform/v2/onramp/orders
Auth: HTTP bearer

Headers

X-Onramp-Partner-Idstring uuid

The Onramp-issued identifier of a disclosed end partner, scoped to an aggregator's developer app. Aggregators integrating Onramp on behalf of multiple end partners set this header to attribute a request to one of their registered partners; omit it for standard, non-aggregator integrations. Only honored for developer apps registered as an aggregator — requires Onramp aggregator onboarding, including registration of each end partner. Contact the Onramp team for access.

Request body

agreementAcceptedAtstring date-time

The timestamp of when the user acknowledged that by using Coinbase Onramp they are accepting the Coinbase Terms (https://www.coinbase.com/legal/guest-checkout/us), User Agreement (https://www.coinbase.com/legal/user_agreement), and Privacy Policy (https://www.coinbase.com/legal/privacy).

destinationAddressstring required

A blockchain address. Format varies by network (e.g., 0x-prefixed for EVM, base58 for Solana).

destinationNetworkstring required

The name of the crypto network the purchased currency will be sent on.

Use the Onramp Buy Options API to discover the supported networks for your user's location.

emailstring

The verified email address of the user requesting the onramp transaction. This email must be verified by your app (via OTP) before being used with the Onramp API.

isQuoteboolean

If true, this API will return a quote without creating any transaction.

partnerOrderRefstring

Optional partner order reference ID.

partnerUserRefstring required

A unique string that represents the user in your app. This can be used to link individual transactions together so you can retrieve the transaction history for your users. Prefix this string with "sandbox-" (e.g. "sandbox-user-1234") to perform a sandbox transaction which will allow you to test your integration without any real transfer of funds.

This value can be used with the Onramp User Transactions API to retrieve all transactions created by the user.

paymentAmountstring

A string representing the amount of fiat the user wishes to pay in exchange for crypto. When using this parameter, the returned quote will be inclusive of fees i.e. the user will pay this exact amount of the payment currency.

paymentCurrencystring required

The fiat currency to be converted to crypto.

paymentMethod'GUEST_CHECKOUT_APPLE_PAY' | 'GUEST_CHECKOUT_GOOGLE_PAY' required

The type of payment method to be used to complete an onramp order.

phoneNumberstring

The phone number of the user requesting the onramp transaction in E.164 format. This phone number must be verified by your app (via OTP) before being used with the Onramp API. Please refer to the Onramp docs for more details on phone number verification requirements and best practices.

phoneNumberVerifiedAtstring date-time

Timestamp of when the user's phone number was verified via OTP. User phone number must be verified every 60 days. If this timestamp is older than 60 days, an error will be returned.

smsVerificationIdstring

A unique identifier for an onramp verification record, in the format onramp_verification_<uuid>.

emailVerificationIdstring

A unique identifier for an onramp verification record, in the format onramp_verification_<uuid>.

purchaseAmountstring

A string representing the amount of crypto the user wishes to purchase. When using this parameter the returned quote will be exclusive of fees i.e. the user will receive this exact amount of the purchase currency.

purchaseCurrencystring required

The ticker (e.g. BTC, USDC, SOL) or the Coinbase UUID (e.g. d85dce9b-5b73-5c3c-8978-522ce1d1c1b4) of the crypto asset to be purchased.

Use the Onramp Buy Options API to discover the supported purchase currencies for your user's location.

clientIpstring

The IP address of the end user requesting the onramp transaction.

domainstring

The domain that the Apple Pay or Google Pay button will be rendered on. Required when using the GUEST_CHECKOUT_APPLE_PAY or GUEST_CHECKOUT_GOOGLE_PAY payment method and embedding the payment link in an iframe. Omit this field entirely for mobile iOS Apple Pay via WebView integration.

localestring

Optional BCP-47 locale tag (e.g. es-ES, pt-BR, en) used to localize the hosted payment page. When provided, it is appended to the returned paymentLink URL and mapped to the closest locale supported by the Apple Pay and Google Pay buttons; unsupported locales fall back to the user's browser language. Any well-formed BCP-47 tag is accepted.

userAuthTokenstring

A reusable, PII-free token issued after a user completes verification in the embedded onramp flow. It encodes only the underlying verification IDs, no personal information. Pass it on subsequent orders to take a returning user straight to the pay button, skipping OTP when checking out to the same wallet.

In the embedded flow, phoneNumber, email, phoneNumberVerifiedAt, and agreementAcceptedAt are handled by Coinbase in the hosted popup and may be omitted from the request even though they are required for the standard partner-verified flow. Reuse is best-effort: an invalid, expired, or different-wallet token still requires the user to verify. Valid for 60 days.
