Backend Integration

We wanted help with integration of Constant contact to our server-side. We are looking to Post data into Mail listings. Right now, we are able to get the Auth_code, But if we use the same Auth code while getting the Access Token we are getting the error message "error_description": "The authorization code is invalid or has expired.". Even though we are generating a new code, the error still persists.
