Not receiving any webhook events in development environment

API Endpoint(s) and/or Zoom API Event(s)

We have an Event Subscription in our App with 2 events registered:
Meeting - Start Meeting
Meeting - End Meeting

Description

We have our app which has been in development and production use for over a year now.

Recently we discovered an issue with our signature validation check on the webhook events when there was a unicode character in the request payload. At some point while trying to test it on our development environment, we stopped receiving webhook events altogether but only in the development environment.

  • No changes were made in our app config at all, only in our API that receives the events
  • The URL still shows as validated in the event subscription config
  • We are seeing no indicators that our API is being hit, where as before we were seeing the request with a 401 response.
  • We are seeing nothing in the Logs on App Marketplace
  • The APIs we use to managed meeting rooms works without issue – We are able to create meeting rooms, join them, and conduct the meeting without any issues

Error?

No error, instead not receiving anything at all.

How To Reproduce
Steps to reproduce the behavior:

1. Request URL / Headers (without credentials or sensitive info like emails, uuid, etc.) / Body

None since its a webhook event

2. Authentication method or app type

OAuth app using “Default Header Provided by Zoom” for Authentication header.

3. Any errors

No

@elisa.zoom or someone else can I please get some support on this issue?

I’ve had a support ticket closed and no response from our contacts at Zoom in 2 weeks.

This is affecting our service in production - any meetings with unicode characters are requiring manually correction by our admins after a meeting happens.

We have a fix in our development environment, but we can not validate it because of this service issue, therefore we cannot confidently deploy this to production.
