Migrating previous order using api with previous fulfillment date

[QeRetail-Expert]

Hello,

I am migrating orders in shopify from another platform and i want to fulfill that order with the actual date which comes from another platform (which is past date).

But when i create order and create fulfillment with created_at with actual date of fulfillment, it take the current date when i migrate order into shopify (eg. fulfillment date is 21-02-2019 and migration date is 07-06-2023. Then it takes 07-06-2023 as the fulfillment date rather than 21-02-2019)

Can anyone please help me how i can pass the actual fulfillment date.

I am using REST fulfillment api to create fulfillment for order.
