Ours is a fulfillment app. As part of the new fulfillment workflow which would be enforced by July 1st, we are supposed to create a new fulfillment service(it contains a callback to our fulfillment app) and register it to the shops, now let us say the product in that shop is mapped to a new fulfillment service, then all the orders created with that product would be fulfilled using the new fulfillment workflow. So the change here is that earlier, locations used to be mapped to the product, instead, fulfillment service would be mapped to the product.
Till now everything is fine, now let us say this product needs to be fulfilled by both our company and another company say “X”, and we only mapped our fulfillment service to the product, may I know how the order(associated with this product) gets fulfilled by company x in this case, because only one fulfillment service can be mapped to the product, and only our company fulfillment service is mapped to the product but not the company “X” fulfillment service
