GTW OnDemand Webinar Integration with Marketo error "Webinar Doesn't Exist"

[CathyDanahy]

What happened after the 4/30/2020 update that caused the On-Demand GTW from being seen by Marketo?

Has anyone else experienced this Bug?

Event set up 4/21, last checked 4/27 everything was working fine.  Now we get the "Webinar Doesn't Exist" message when it does on the GTW side.

Tech Support has not been forthcoming or helpful.

Hoping someone else has found a work around.

Hey Cathy,

Do you know what Marketo said about the disconnect?  I heard several days ago that they may not have updated to the latest GoToWebinar APIs.
