Getting Started

Authentication

The Extend API uses Bearer token authentication for all API requests. You’ll need to use your API token when instantiating the client if you’re using the SDK or in the Authorization header of each request if you’re using the API directly.

Log in to the Extend dashboard and obtain an Extend API key from the Developer Settings page. More details on authentication, including error handling.
