My company migrated to Shopify almost two months ago. In the process of migrating we imported open orders from our previous site. Some of these open orders have completed fulfillments. We import the orders through CSV and then apply fulfillments and cancellations through the GraphQL API. For fulfillments we use the fulfillmentCreateV2 mutation. This mutation doesn’t give an option to set the shipped_at date so all the migrated fulfillments have a shipped_at date of the day we imported the fulfillment.
As days go on we find some orders that were missed in the migration. I import the orders but the shipped_at date causes an issue with our financial team as these fulfillments appear on current fulfilled order reporting.
Has anyone been able to alter the shipped_at dates on fulfillments?
