Is it possible to export all of a person's details aside from the Activity Log history that are in the Info, Company Info, Opportunity Info, SFDC Info tabs?
You can get all the Info, Company Info, and SFDC Info tabs by creating a smart list that will target only this one person (for example by selecting email="firstname.lastname@example.org"). Then you can export this person's data by exporting this list and selecting all fields. This will get you all the person fields. See pages 34-36 in Marketo's GDPR ebook here: The GDPR and The Marketer: A Practical Guide for the Marketo Customer for very detailed instructions
The REST API offers almost all this, unless you have your Marketo sync'ed with a CRM (in which case opportunities will not be accessible).
Is there documentation of how we can use the REST API to export all the data? This would be a good option to have as well.
Documentation is not enough, you will also need a developer
Thanks Pavel - That's exactly what I needed.
You will not have opportunity info that way...
