How to Set Up Authentication for Google Calendar API in Bubble Plugin API Calls?

** I am integrating the Google Calendar API and have configured the credentials correctly. Using Postman and other programming languages, I am able to send requests to my project in the Google Developer Console, pass the OAuth 2.0 protocol, and execute methods like create event and delete event in Google Calendar.

However, I am unable to authenticate in Bubble Plugin API Calls. As shown in the configuration screenshot, I have set everything up correctly. Despite this, I cannot pass the OAuth 2.0 protocol in Bubble. Interestingly, I can authenticate using Authentication: None or Self-handled with the access token I obtained from Postman.

How can I correctly authenticate using OAuth2 User-Agent Flow in Bubble? I suspect that I am encountering issues with the access token.**

Did you “initialize” the auth in debug_mode with “Signup to social network” action? You will not be able to initialize call until this is done. After, you can add API Calls. API Connector doesn’t refresh token but this will be done for users.
