# API Reference

> Trunk APIs for building custom integrations.

## REST API Overview

Trunk provides HTTP REST APIs for each of our features. The APIs use status codes to indicate the success or failure of requests, return JSON from all requests, and use standard HTTP response codes. All API requests must be authenticated.

## Available APIs

* [Flaky Tests](../../flaky-tests/reference/api-reference): for accessing information like quarantined tests in your repo.
* [Merge API](../../merge-queue/reference/merge) : for controlling the Trunk Merge Queue.

## Authentication

Authenticate to the API with an API token using the header `x-api-token`.

### Finding your API token

You can find your API token in the [Trunk App](https://app.trunk.io) by navigating to **Settings** → **Organization** → **General** and scrolling to the **API** section. The **API Token** field displays your token.

Click the **eye icon** to reveal the token, then the **copy icon** to copy it to your clipboard. Pass it in the `x-api-token` header on any request to Trunk's REST APIs.

**If you are an admin**, a **Rotate** button is available next to the API Token field. Rotating immediately invalidates the previous token, so any integrations using the old token will need to be updated.

**If you are not an admin**, the **Rotate** button is disabled. Only administrators can rotate the API token.
