David, Thank you for your message. I have one more question regarding API V3. I'm following the steps here for server_flow Oauth2.0: https://v3.developer.constantcontact.com/api_guide/server_flow.html In step 4, I'm not sure where to find "client_secret". I went to "My Application" but all I see is API Key which is "client_id". Where is client_secret ? Thanks, Meysam.

Hi, I know there is an API php library for v2 here: https://developer.constantcontact.com/libraries/libraries.html and I'm sure it's not compatible with API v3. Is there any API library for V3 ? Thanks.
