# Authentication

> Using a Bearer token to call the API.

## Authentication

Authentication is a mandatory step to interact with the Cartevo API.\
All requests must include a **Bearer Token** sent in the HTTP `Authorization` header.\
Without this token, your calls will be rejected with an authentication error.

***

### Expected Format

The token must be included in each HTTP request as follows:

```http theme={null}
Authorization: Bearer <token>
```
