How to change the order fulfillment status from unfulfillment to in progress?

[TuyenND]

Hi everyone, I want to change the order fulfillment status from unfulfillment to in progress with GraphQL API, but I can't find the API to handle this. I'm using version 2023-01. Please someone help me resolve this problem!
Thank you.

Hi @TuyenND,

I think this is the one your looking for here

[TuyenND]

Yeah, I tried your solution, there is something I get when I call the fulfillmentOrderAcceptFulfillmentRequest GraphQL API: 

The fulfillment order's assigned fulfillment service must be of api type

I've handled all steps here 

This is the response when I get

Array
(
    [data] => Array
        (
            [fulfillmentOrderAcceptFulfillmentRequest] => Array
                (
                    [fulfillmentOrder] => 
                    [userErrors] => Array
                        (
                            [0] => Array
                                (
                                    [field] => 
                                    [message] => The fulfillment order's assigned fulfillment service must be of api type
                                )

                        )

                )

        )

    [extensions] => Array
        (
            [cost] => Array
                (
                    [requestedQueryCost] => 10
                    [actualQueryCost] => 10
                    [throttleStatus] => Array
                        (
                            [maximumAvailable] => 1000
                            [currentlyAvailable] => 990
                            [restoreRate] => 50
                        )

                )

        )

)
