Help with Marketo - Bizzabo Integration

Hello,

 

We’re planning a custom integration between Marketo and Bizzabo for our upcoming webinars and would like some guidance from anyone who has done something similar.

Our planned flow is:

  • Use a Marketo form to capture webinar registrations.

  • Send the registration data to Bizzabo via a webhook.

  • After the event, retrieve attendance and engagement data back into Marketo, ideally via a webhook or API.

We're currently exploring how best to set this up, especially:

  • Structuring the webhook payload to send from Marketo to Bizzabo

  • Authentication or headers needed for Bizzabo API

  • How to receive post-event data like attended, no-show, engagement score, etc., back into Marketo

  • Any pitfalls or limitations to be aware of

If anyone has done this type of Marketo to Bizzabo integration—or something similar—I’d really appreciate if you could share:

  • The high-level steps you followed

  • Sample payloads or webhook config

  • Tips or lessons learned

There’s no such thing as a direct inbound webhook to Marketo.

 

All inbound connections use the REST API. If the source system sends stateless webhooks, they must be sent to an intermediate API gateway before being transformed into Marketo API calls.

 

  • Send the registration data to Bizzabo via a webhook.

There’s no such thing as a direct inbound webhook to Bizzabo, either.

 

Just as in the above case, your Marketo webhook must hit an intermediate gateway to be transformed into Bizzabo API calls with valid OAuth access tokens.

 

  • How to receive post-event data like attended, no-show, engagement score, etc., back into Marketo

Poll the Bizzabo API to get results in bulk, then bulk upsert Program Members using the Marketo API.

 

With respect, have to say it doesn’t sound like you’ve done much legwork yet. Nothing you’ve listed is impossible. But this community isn’t the place to design a complex and mission-critical architecture from scratch.

 

Have you considered talking with people experienced at Marketo integrations so they can help you design this?
