Im looking to fulfill orders through the REST API. In order to do that, is it necessary to setup a FulfillmentService as listed here or can you make a single Fulfillment request? We are using a custom middleware to manage shipping and fulfillment for a single store and need to simply make a request to set an order as fulfilled with a tracking number.
I was planning to use this endpoint, passing the tracking info in the body as described here.
We only have one fulfillment and one inventory location. My understanding was that we could make a single Fulfillment request rather than setting up a FulfillmentService resource, but I want to make sure that this approach has not been deprecated.
