# You get an error similar to response_type is missing

This is an easy one to diagnose, and to fix. When you make an authorization request, that request must include several mandatory parameters (see the article [Authorization code + PKCE grant type](https://techdocs.akamai.com/identity-cloud/docs/the-authorization-code-pkce-grant-type) for more information). As it turns out, **response\_type** is a required parameter; if you forget to include r**esponse\_type** you’ll get an error message like this:

Likewise, **scope** is a required parameter. Leave out the **scope** parameter and you’ll get this error:

To avoid these problems, just check your authorization request and make sure it includes all the required parameters.
