Coinbase Onramp API

The v2 Onramp APIs are an evolution of our [v1 APIs](https://docs.cdp.coinbase.com/api-reference/rest-api/onramp-offramp/), designed to make the fiat-to-crypto experience feel native to your applications for higher conversion and less friction. These APIs only cover a subset of Coinbase Onramp functionality as described below, for all other use cases please refer to our [v1 APIs](https://docs.cdp.coinbase.com/api-reference/rest-api/onramp-offramp/). ## Supported Use Cases #### Guest Checkout Onramp (Apple Pay & Google Pay) This use case allows you to offer an Apple Pay or Google Pay onramp experience with debit cards in your app without users needing to create or log into a Coinbase account. Our API returns a `paymentLink` URL that renders an Apple Pay or Google Pay button for you to load in a webview or iframe in your app, making the onramp experience feel native to your application. Refer to our [detailed integration guide](https://docs.cdp.coinbase.com/onramp/headless-onramp/overview) for more information on the limitations and requirements of this use case. See our [onramp mobile demo app](https://github.com/coinbase/onramp-demo-mobile) for a reference implementation. #### Hosted UI Onramp This use case enables you to offer a full-featured onramp experience by redirecting users to a Coinbase-hosted page where they can choose to log into their existing Coinbase account or proceed as a guest. The Onramp Session API generates secure, single-use Onramp URLs with customizable parameters, allowing you to control available payment methods, preset transaction amounts, and cryptocurrencies for a tailored user experience. Refer to our [guide](https://docs.cdp.coinbase.com/onramp-&-offramp/onramp-apis/generating-onramp-url) for implementation details and customization options for this use case.
