Hello @WCCGoldenApple , @QgivP & @user915548,
Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.
We greatly appreciate you bringing this to our attention. We have been able to replicate the invalid scope responses you have received when encoding the scopes portion of the authorization request URL. I’m going to bring this to our development team for further investigation and update our documentation accordingly. In the meantime, we have found through testing that excluding the scopes portion of the URL from being encoded so the “+” characters generate as “+” and not “%2B” will allow the authorization request to be successful.
Please let us know if you have any other questions!
Regards,
