Facebook Shop supports directly selling on Facebook. Since the tracking pixel cannot be installed, Attribuly cannot directly track user behavior in Shop, but it can attribute orders to the Facebook Shop channel.
Orders completed on Facebook Shop will be attributed to Facebook Shop. If the traffic is directed to your store and completed, it will still be attributed to the corresponding Facebook ad.
If the order is placed in your offline store, and there is no online touchpoint information. This order will be attributed to a POS order.
