Does anyone know if Marketo can update custom fields on a task object in Salesforce, and if so, how do you do it?
Not it does not. Vote here:
Make all task/event fields modifiable in Create task flow step
Pass Custom Task Values to Salesforce
Create task for a custom field of type Lookup we've created in SFDC
Use all task/event fields in SFDC activity-related triggers and filters
Marketo Consultant @IFG thanks - I was hoping this wouldn't be the answer. I'll go ahead and up vote all 4!
