Migration Fulfillment api orders questions

Hi,

Currently we download orders from shopify using below api.

https://company.myshopify.com/admin/api/2021-04/orders.json

and we do shipment marking using below api.

https://company.myshopify.com/admin/api/2021-04/orders//fulfillments.json

Currently we are not using any fulfillment services, as per the below migration guide we understand only the existing shipment marking using “/orders//fulfillments.json” api might not work by 31st March 2023, Is there a way we could perform shipment marking without creating fulfillment service as per migration guide. We just need update the shipment status in shopify.

Hi there,

Are you fulfilling the orders or only updating the fulfilments with the tracking information?

Cheers,

Gary
