Square Connect API customer_id not populated when Listing Transactions
<p>I am using v2 of the connect api to list transactions for a specific date range.  All of the transactions that I get back never have the customer_id populated in any of the Tender objects even though I know some customers are known by square.  I am able to successfully retrieve all of the other data.  The resource I am using is locations/{location_id}/transactions and specifying the begin_time and end_time in the query string .  What am I missing?   </p>

<p>Edit </p>

<p>I downloaded my transactions using the export function and none of the transactions have a customer name or Id.  What is required to have this information populated?  Maybe that is where I am going wrong.  Does this have to be a customer I add myself or does it include customers added by Square?  Is it required the customer to have their receipt sent to them by email?    </p>
