    ## Authentication


    The Libredesk API supports two authentication methods:


    ### 1. Basic Authentication

    Use your API key and secret with Basic authentication:

    ```

    Authorization: Basic <base64_encoded_api_key:api_secret>

    ```


    ### 2. Token Authentication  

    Use your API key and secret with token authentication:

    ```

    Authorization: token api_key:api_secret

    ```


    To obtain API credentials, generate them from your agent profile in the
    Libredesk dashboard.
