Has anyone had luck setting up token retrieval in Postman API?   I can get the token when going through the folder authorization steps, but not when trying to create POST/GET requests. Using the "Get New Access Token" method in the folder authorization, I am required to login every time. This is not sustainable.   For anyone with experience with this, I am attempting to follow the steps here. 1. In Postman, I create a GET request. GET https://api.cc.email/v3/idfed? Params: client_id: {{clientid}} (same as in the Get New Access Token process) redirect_uri: https://localhost (same is in the Get New Access Token process) response_type: code scope: contact_data+campaign_data   2. This returns an HTML form that does not seem to work in Postman.   3. I am expecting to get an authorization code, but I do not see where this comes from.    4. Attempting to send a POST request to the https://idfed.constantcontact.com/as/token.oath2?code=????&redirect_uri=https%3A%2F%2flocalhost&grant_type=authorization_code   Headers:  Authorization: Basic (base64 {{clientid}}:{{API Secret}}) Content-Type: application/x-www-form-urlencoded   Response is: { "error_description": "unable to parse Authorization header javax.security.auth.login.LoginException: No credentials provided with BasicAuthorization", "error": "invalid_client" }   ...
