# Generate an API Token

Tokens are used to interact with the Flare API.
They can be generated using an API key provided via the Authorization header.

API tokens expire after 1 hour.

The endpoint returns an API token via the response body, but also via cookies which can then be used in future HTTP requests.

For more information about authentication, see the
[API Authentication Guide <Icon icon="book" size={16} />](/concepts/authentication/).

  ```json Response Schema theme={null}
