Syncing Marketo custom object fields to a campaign member on Salesforce

[Tamir_Belzer_TB]

Hi, we are using a custom object in Marketo to capture some attendance fields of webinars, meaning attendance duration, QA, Poll and survey answers and we want to add this data to the campaign member on Salesforce. Anyone has any idea how can we achieve that? Thanks

The only way is call a webhook-compatible service. It loops back to grab the CO data via REST, then writes to SFDC using the SFDC API. And of course you have to ensure the person themselves has been synced to SFDC first, i.e. they have an SFDC ID stored in Marketo.

But all this is pretty tricky to engineer (though we’ve done it under duress!). It might be better to rethink why you’re using COs instead of PMCFs, if the data is important to have in SFDC. If you use PMCFs you can sync them directly to Campaign Member custom fields using the built-in Marketo feature.
