There are two methods of authentication; [Client-Credentials method](https://www.rfc-editor.org/rfc/rfc6749) and [PKCE (Proof Key for Code Exchange)](https://www.rfc-editor.org/rfc/rfc7636) method. In each of the methods, You will get an `ACCESS_TOKEN`. You need to use an `"Authorization"` HTTP header to provide your `ACCESS_TOKEN`. For example: `Authorization: {ACCESS_TOKEN}`. scheme: bearer type: http bearerFormat: JWT ````
