Hi Davide,
Thanks for your message.
Route 66 uses only the OpenAI Responses API for all AI-related features. No other OpenAI permissions are required.
Because of this, enabling only the Responses API on the API key should work correctly, since that’s the only endpoint we use.
If you previously modified permissions on an existing key, please note that changes may take some time to propagate. To avoid this, we recommend creating a new API key with only the Responses API enabled and using that in Route 66.
The fact that everything works when all permissions are enabled confirms that the integration itself is functioning correctly.
Regarding your second question:
At the moment, Route 66 is available only for Joomla. There is no WordPress version currently available.
Let me know how it goes with a new key, and I’ll be happy to assist further if needed.
Best regards,
Lefteris
