The documentation for the `webinar.updated` webhook event mentions that the JSON payload should contain a field called “time\_stamp” but the sample JSON for this webhook event does not include such a field. Moreover, the documentation says this field is “required” therefore it is my understanding that the payload I get from Zoom must include this field. This leads me to conclude the sample is missing this required field
