# API reference

Source: https://docs.revoplyai.com/api-reference/

> The machine-readable contract generated from the OpenAPI specification, with the flow trigger endpoint and every webhook event.

The pages in this section are generated from the OpenAPI 3.1 specification
([download](/resources/openapi/)), so they match what the API does.

**What it contains today:**

* [`POST /hooks/{token}`](/api-reference/hooks/start-flow-from-hook/): the endpoint your
  system calls to start a flow. Its token is its credential, so this page has no in-browser
  console: call it from your server. The guides are under [Flow triggers](/flow-triggers/).
* Every [webhook event](/webhooks/events/) we send to your endpoints, with its fields and
  an example.

**What it does not contain yet:** the REST API (`https://api.revoplyai.com/v1`) for reading
contacts and conversations and sending messages is not available. Its endpoints, API keys
and in-browser console will appear here when it is published, and the
[changelog](/resources/changelog/) will announce it.
