Built for developers
Three requests. That's the integration.
REST · JSON · OpenAPI
From sign-up to first payment in an afternoon
Plain REST and JSON, no SDK required. Amounts are decimal strings, requests are idempotent by reference, and the API is documented in an OpenAPI spec that is checked in CI, so the docs can't drift from the API.
