# 1Funnel Developers

> Documentation for approved 1Funnel integrations.

Build approved integrations against the 1Funnel platform. This portal is the public source for integration guides, API references, and release notes.

<Note>
  The External Integration API is not generally available. Nothing on this page
  is a production endpoint, credential, or response schema.

## Integration surface

The portal documents publicly approved integration interfaces:

* REST APIs described by an approved OpenAPI 3.1 contract
* Outbound webhooks, where 1Funnel sends events to your application
* Inbound webhooks, where your application sends events to 1Funnel

No public REST contract or webhook catalog is published yet. Pages in this portal describe how those contracts will appear. They do not describe internal services.

## Stay current

Product changes that affect integrators are listed in the [changelog](/resources/changelog). Documentation changes land through reviewed pull requests before they are published.
