How do I fulfill a single line item in a fulfillment order without closing the order?

[sitver]

I want to fulfill one line item from a multi-item fulfillment order without closing the whole fulfillment order. The documentation implies I can do this by sending  'fulfillment_order_line_items' with a 1-item array of the item I want to fulfill, but when I do that, it closes the whole fulfillment order, returning an error when I try to fulfill other items from the fulfillment order.

What am I doing wrong and how do I accomplish what I'm trying to accomplish?

The specific request I'm sending:

axios.post(

/// Optionss:: line_items_by_fulfillment_order (Arr), message (optional), notify_customer (boolean defaulting to false)

base_url + '/admin/api/2023-04/fulfillments.json', 

 {

'fulfillment': {

message: "The message we're sending",

'line_items_by_fulfillment_order': [

 {

'fulfillment_order_id': fulfillment_order_id,

'fulfillment_order_line_items': [{'id': <item_id>, 'quantity': 1}]

 }

 ]

 }

 },

 { headers: { 'X-Shopify-Access-Token': <our_auth_token>, 'Content-Type': 'application/json' } }

 )

HI Sitver,

The fulfillment request you're seems to be correct according to Shopify's GraphQL Admin API documentation. However, it is worth noting that Shopify treats each fulfillment_order_line_items array as a separate fulfillment request.

If a fulfillment order has multiple items and only some of them are moved in a request, then a new fulfillment_order is created for the remaining items that were not moved. The status of this new fulfillment_order is open.

So, if you're trying to fulfill another item from the original fulfillment_order after creating a partial fulfillment, you might be getting an error because that original fulfillment_order is now considered closed.

Instead, you should be able to fulfill the remaining items from the newly created fulfillment_order. Check the response of your initial partial fulfillment request to get the ID of the new fulfillment_order and use that for your next fulfillment request.

Hope this helps!
