There may come a time when it is necessary to perform a full sync of Pardot prospects data with your CRM data. For example, if you want to run a dynamic list with a rule looking at a Custom Object field value, you may need a full sync of data to ensure it is up to date.
Previously, you would need to contact Pardot Support who could take up to 3 working days to get back to you before performing the task. Now, you can do this yourself by adding some form fields.
