TLDR: According to HeyGen, the HeyGen Zap does not work.
After a lot of troubleshooting the HeyGen “Avatar #ID not found or no longer available” and the throttling error with HeyGen, I received the following feedback from their tech support today:
We currently have a bug with Zapier which prevents this part from working…..[edit]…..For the time being, likely it won't be possible to use this Zapier functionality. We appreciate the understanding and we'll let you know once the issue is fixed.
