One thing to keep in mind while initialing trying out syncing is Account Engagement (Pardot) checks for changes in Salesforce and Account Engagement (Pardot) up to every 2 minutes. If you‘re seeing slower sync times, contact support. If you’re updating a large volume of records at a time, it can take longer for all changes to sync.
Once you download the guide below, make sure you verify the syncing rules and that the account you use to connect has the correct permission sets. As always if you need any assistance or have a quick question feel free to reach out.
