I am trying to create Fulfillment from the Fulfillment order but can't find the relevant REST Admin API. In the official documentation it only gives the GraphQL mutation that can be called -fulfillmentCreateV2.
I am able to send a Fulfillment request and accept it via the rest api but can't seem to find the api to actually create the Fulfillment from the FulfillmentOrder.
I am also looking for same this in REST api but not found any which is already available in the GraphQL api as per below documentation.
For fulfillment orders that return CREATE_FULFILLMENT as a supported action, the fulfillmentCreateV2 mutation will allow you to create fulfillments.
I believe they want us using the GQL fulfillmentCreateV2 mutation. When all items are fulfilled, it will mark the fulfillment as complete
