# CLIENT\_SECRET\_BASIC Flow

For applications that have the `tokenEndpointAuthMethod` property set to `CLIENT_SECRET_BASIC`, you authenticate the token endpoint by setting the `Authorization: Basic` HTTP header in the request URL. The value is a Base64-encoded representation of "username:password", in which the `username` is the `client_id` and the password is the `client_secret`.

## What you'll do

You will send an authorization request to start the workflow.

* POST request to the authorize endpoint.

* POST request to submit the user's username and password.

* POST request to get the access token.
