My app looks at orders (by polling by date or via a webhook) and needs to determine whether the order was made through POS or online. order.source does not seem to be set in many circumstances. How do I determine if this was a POS order? ---

To determine if an order was made through the Square Point of Sale (POS) application, you can look at the `Order.source` field. However, as you’ve noted, this field might not always be set. In such cases, you can use the `Payment.application_details.square_product` field associated with the order’s payment. If this field is set to `SQUARE_POS`, it indicates that the order was created through the Square POS application. Additionally, you can check the `Order.fulfillments` field. Orders created through Square POS might have fulfillment details that are specific to in-person transactions, such as pickup or delivery options that are typically associated with POS orders. If these fields are not sufficient, you might need to rely on other contextual information or business logic specific to your application to infer the source of the order. _This answer was reviewed by @Bryan-Square._ ---

You can use the `Payment.application_details.square_product` field associated with the payment from the [Payments API](https://developer.squareup.com/reference/square/payments-api) to determine where a payment was take. 🙂
