How do I get SKU in line_items from FulfillmentOrders?

[thegamecrafter]

I'm trying to build a fulfillment workflow using the APIs as described here: https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments

However, the REST API appears to be missing a critical piece of data. The line items don't contain SKUs. Yet everything works off of the SKUs, including the inventory APIs described on the same page here: https://shopify.dev/apps/fulfillment/fulfillment-service-apps/manage-fulfillments#step-9-share-inven...

Am I missing something? How do I get the REST API to give me the SKUs in line items? I am aware I can get them via GraphQL, but if I have to use GraphQL, then why even have REST APIs?

What call are you using, exactly?

SKUs will show up in the data. If you use this, it definitely works:

/admin/api/[api version]/orders/[order number].json

I'm using the new fulfillment system as it is linked in the original post. The REST endpoint is:

GET https://{shop}.myshopify.com/admin/api/{api_version}/assigned_fulfillment_orders.json?assignment_sta...

Okay, I don't see it in that particular call but you can get it from the other call they describe:

https://{shop}.myshopify.com/admin/api/{api_version}/fulfillments.json

Yeah, but with the new system you have to accept a FulfillmentOrder before you can create a Fulfillment. This is why it's a problem. It's going to be a problem for everyone using fulfillments in a while because they're ditching the old Fulfillment system according to the attached note on this page: https://shopify.dev/apps/fulfillment/fulfillment-service-apps

Caution

If your app is using the Order (REST or GraphQL) and Fulfillment (REST or GraphQL) API resources to fulfill orders, then you're using a legacy workflow. As of API version 2022-07, the legacy workflow will no longer be supported.

By API version 2023-04, all apps should be using the FulfillmentOrder object to manage fulfillments. For more information on fulfillment-related resources that were removed in API version 2022-07, refer to the 2022-07 release notes.

Okay but even so, you are getting item IDs and inventory IDs. You can look up the SKU from the inventory ID, if not the item ID.

[thegamecrafter]

Yes there are absolutely work arounds, including using the GraphQL version of this same object instead of REST (which is what I did). My point is that every other part of the new FulfillmentOrders API uses SKUs, not product IDs. Thus the REST endpoint for assigned_fulfillment_orders should include SKUs, not product IDs.

[Snodgers]

Understood. I was just trying to explore options but I absolutely agree.

There's no good reason to omit the SKU from the line item data. Shopify needs to address this problem.
