## Using basic auth <a href="#using-basic-auth" id="using-basic-auth"></a>

To configure this credential, you'll need:

* A **Password**
* A **Requested With** string: Enter a user description, like a user agent, or keep the default `n8n application`. This sets the required `X-Requested-With` header.
