Hi Enrique Arana or Enrique Arana (I see 2 of you in this community)
Late visiting this page for a while, have you managed to get success with your webinars through Marketo?
We've been successful with the integration and are running webinars regularly.
I had the same issue with the On24 platform - but added a wait step like mentioned above and the change program status > registered and it works for EMAILS only. I have yet to find success with landing pages - was told that it does not populate on landing pages.
Thanks.
