# Authentication

Trainer API uses Bearer token authentication.

Send your API token in the `Authorization` header:

`Authorization: Bearer <token>`

## Get an API token

Get your token from your [Profile](https://www.runcomfy.com/profile) page (avatar menu > **API Token**).

If you regenerate your token, the old token stops working immediately — update any integrations.

## Keep your token secret

Do not ship your token in client-side apps (browsers, mobile apps). Route requests through a server-side service you control.
