API Endpoint(s) and/or Zoom API Event(s)
/v2/users/me/meetings
Description
I login to Calendly, go to Integrations & apps and click Connect Zoom for myself and enter my credentials.
I then book a meeting with Zoom as the location.
Calendly is unable to retrieve the Zoom link.
I do the same test with another personal account, it works fine with no issues.
In the activity logs, I can see the POST request with a 400 error.
I also tried adding the user in the authorization section of the Zoom marketplace for Calendly and it did not work.
I don’t know what to look for since there are a lot of settings in an organization account.
The logs don’t say much except the 400 error and I cannot see the content of the POST body.
I don’t think its a Calendly issue since I am able to use my personal zoom account with the same Calendly and it works without issues.
It seems to be a Zoom account issue but I don’t know what.
Were they able to look at your account and resolve the issue?
I checked the API logs for the account you’re posting with and I only saw successful call logs for the Calendly app. Are you using a different account from this one? If so, I can private message you for you to send me that one.
No the issue isn’t resolved yet.
Calendly support can’t find out what the issue is and believe its an issue with the Zoom account.
I have a ticket opened with Zoom Support and the person is checking with seniors to see what the issue is as they can’t find what the problem is yet.
These are the tracing ids of the 400 errors from Calendly to Zoom, with the dates EST time.

I tested with 3 accounts account in Calendly Zoom Integration.
My personal (which works fine)
And two which are under the same organization.
One works with no issue, the other fails.
The failing one is an admin account too, so its weird.
I am waiting for a response for now.
Hi @Kheang_Hok , please respond to my private message with the email for the user for which you’re experiencing the issue and I’ll take a look. You’ll see the private message in your dev forum notifications.
Hi @Kheang_Hok I looked at the users on the same account and see no distinguishable changes. Please have the user un-install then re-install/authorize the Calendly app. Then try the call again.
The root cause was the presence of deactivated alternate hosts in the list. The entries I advise to remove were no longer associated with active users in the your organization. The expected behavior is that when a user is deactivated, they should automatically be removed from the alternate host. I will consult this further with our backend team and will keep you updated on the progress.
