Fulfilment order line item location changes

Webhooks and Events
1

I’m using the fulfillment_orders/moved webhook to detect when fulfilment order line items have their location changed in the Shopify UI.

I’m seeing a strange issue with the fulfillment_order_line_items_requested section in the webhook payload:

  • Sometimes this is just an empty array, so I have no idea which fulfilment order line items had their locations changed.
  • Sometimes it contains a fulfilment order line item id that no longer exists in Shopify, so again, I can’t know what was changed.
  • Other times it will return the correct id of the fulfilment order line item which had it’s location changed, which is fine.

The behaviour of missing/invalid ids appears to be random. Is this perhaps due to a data propagation issue/race condition within the Shopify platform?

I’m currently unable to consistently track fulfilment order line item location changes at this point.

Thanks.
