Answer 1

You're getting this error because sending requests with authorization in the query parameters is being deprecated.

Support for passing credentials via querystring is deprecated and will be forbidden in a future version of the API. Please update your API client as soon as possible.

You must now provide the parameters in an authorization header

Authorization: Pardot api_key=<your_api_key>, user_key=<your_user_key>
