Is it possible to update a SFDC custom object field with REST data? I'm looking for an easy solution but I've heard it's not possible. Thoughts?
Just want to point out for all reading this thread that this answer is not correct. You cannot interact with SFDC custom objects via the Marketo custom objects APIs.
+ 1. In Marketo, Your SalesForce custom objects are read only. You can't update them with the custom object marketo REST API as far as I'm aware.
I'm assuming there have been no recent changes related to this and writing to Salesforce custom objects still requires the Salesforce API? Or any news of forthcoming changes?
