We are doing an integration with Google Calendar Api, trying to publish events in a calendar, and then add them to the invited users (attendees) in their primary calendars. After doing a couple of tests and publications we skip the error message:
Calendar usage limits exceeded. [403]
We have read the documentation and the limits of petitions, but we are not passing at any time of that limit, and we skip the same error. We have seen in forums and in the same documentation of the API, that the reasons can be diverse, like the publication of more than 25 calendars, overcome the 10,000 events, etc.
In our case, we do not overcome any of those limitations. To get an idea, we did not surpass the 200 events in a couple of days. And since we started testing, events don't exceed 500. That is why we are trying to contact you as the last solution, because we do not know where the problem is.
Is there are any daily or sendings attendees exact limits ? Because we need to launch and update many of them, and don't know how to do it. How can we publish and share this events without having the limitation failure? In our Google Console we say that the quota still remain 1.000.000 queries per day.
To make myself understood, my procedure is: I have a general Calendar with a Json Keys, and I publish all my events in it. Then, I trying to add attendees and publish(share) part of my events with them. But I have the same error for days. I know that Google Calendar limits the number of invitations a user can send to external guests 100-300 guests exactly. But I do not know if is a limit per hours, days, or account? How we can do to publish many events with attendees without limits? Is there a solution for that?
