Clarification for Fulfillment API deprecation

I’d like some clarification on if the Fulfillment API is being deprecated or not.

My app currently uses the Shopify FulfillmentOrders API to retrieve a list of fulfillment orders, and once it has the orders and a list of acceptable actions, it uses the Fulfillment API endpoint POST/admin/api/2023-01/fulfillments.json to create a fulfillment on the fulfillment order. Is this process (using this Fulfillment API endpoint) going to to be deprecated?

Only some end points on the 2022-04 fulfillment API are being deprecated.

The process you are describing is not being deprecated.

As you are using the 2023-01 API already, the upcoming deprecations on
march 31st March will not affect your app.
