I'd like to receive a "Shipment notification callback" when orders are shipped. But, I'd like to be notified of all shipments regardless of the store it came from. In reading the docs (https://shippingeasy.readme.io/docs/shipment-notification-callback) it sounds like the callback notification would only be sent for an order "that was added to ShippingEasy via the ShippingEasy API". So I'm guessing I wouldn't receive a callback for orders from our other stores (e.g. BigCommerce, Etsy, Amazon, etc.) Is that correct?
Is there any way to receive a "Shipment notification callback" regardless of what store the order came from?
