*As of September 21, 2020, some Zoom users are experiencing caption delays between when it is sent from to when it appears in Zoom. There is an open support ticket with Zoom, which we hope will be resolved soon. If you experience caption delays, utilize one of the other two options as a fallback.


The following instructions explain how to integrate specifically with the Zoom caption API token method.
