The Google Calendar API Started Monitoring And Limiting Queries On A Per-Minute Basis
https://developers.googleblog.comThe Google Calendar API has changed how it manages API usage. Previously, queries were monitored and limited on a daily basis. As of May 2021, queries started to be monitored and limited on a per-minute basis.
This introduces better behavior when your quota is exceeded, as requests are rate-limited until quota is available rather than failing all requests for the rest of the day.
