We use that “Account Name” we pulled from the Deal record to search the Customers module in Books (The API name is unfortunately named ‘contacts’).
Once we perform the search correctly, specifying our parameters, we drill down in the JSON to get the ID of the Customer we found.
Learn more about the getRecords integration task. If the code in the video doesn’t work for you, try adding your “connection_name” as a 4th parameter after your search parameter.
