Hello everyone, could someone please assist me? I'm building an AI appointment setter using callin.io. To achieve this, I need to link my Google Calendar with callin.io. I attempted to connect them via the 'Google Calendar Make an API Call' option, but I encountered an error: 'error [403] Request had insufficient authentication scopes.' I've tried everything I can think of to resolve this, but it's still not working.

(I've reauthorized the connection multiple times without success. I've enabled all the correct API keys, entered the correct URLs in the Authorized redirect URIs section, and configured all the necessary scopes, but none of these steps have worked. I've also created new accounts and repeated the process, but that didn't help either.) I consulted the callin.io documentation and followed all the guidelines, but it remained unresolved.
Please, can someone help me fix this issue?

:sleepy:

For retrieving free/busy information from Google Calendar, have you considered using the Get Free/Busy Information module?

Hello,

Regarding your error message “insufficient authentication scopes”, it seems your API Key doesn't have the necessary permissions for the action. Please navigate to your Google console, locate your project and application, and adjust the restrictions there according to your call's requirements.

Kindly inform me if this resolves the issue.

Best regards,
Dimitris Goudis

Hello,

I believe you'll need to initiate a new project within your Google Console and then re-execute the process. If this solution doesn't resolve the issue, please don't hesitate to contact us.

Thank you

No, that's not the case. I've deleted all my previous workflows and started with a fresh one. I've set it up correctly, following all instructions from the community and guides. However, it's still not functioning.

I'm in the same boat, and I'm not sure what to do. I've tried everything I could. Will callin.io fix it?

Hi, welcome to the callin.io community. Have you tried using a different email ID for the connection?
