Approved External Integration API environments will be listed on this page together with their base URLs. The External Integration API is not generally available. Nothing on this page is a production endpoint, credential, or response schema. No environment base URL is published yet. Do not infer a public base URL from any other 1Funnel hostname. Internal, merchant, and operations hostnames are out of scope for this portal. When an environment is approved, this page will record: * the environment name * the base URL * whether it is safe for test traffic * which contract version it serves The API playground remains disabled until the external API security model is approved, including for any future test environment. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
