We have released three new fulfillment related tasks in Flow.
First, you can use the Move fulfillment order action in flow to move a fulfillment to a new location where all the line items are stocked. To give it a try, you can build a workflow from scratch in Flow, or use "Move large fulfillment orders to another fulfillment location" template.
Next, you can use Mark fulfillment order as fulfilled action in flow to create a fulfillment for an fulfillment order. To give it a try, you can build a workflow from scratch in Flow, or use "Fulfill a digital item in an order" template
Lastly, you can use Fulfillment order merged trigger to start your workflows when multiple fulfillment orders have been merged into one.
