I'm implementing ZoomInfo and creating a webhook to map the ZoomInfo data to the fields we've created i.e "ZI First Name" so we don't override the data they have inputted themselves in the form. Since you cannot create CRM fields through Marketo, we created them in CRM in the only way possible which is as a custom field. When I set up the webhook, it will only map to standard lead fields and the custom fields we created, although synced, will not pull up as an option. Does anyone know of a work around? It seems this integration works better with Salesforce than CRM and the help document ZoomInfo links to is for Salesforce integration. The CRM integration documentation doesn't exist yet, so I'm hoping I didn't buy a product that doesn't work with CRM!
