What should be the API call flow for order shipping?

[HoboCY]

My application wants to integrate shopify order fulfillment
The general process is as follows:
1. Obtain paid orders shopify
2. Ship directly from our system
Now I have obtained the order, but I don't know how to operate the order fulfillment. I can't get the fulfillment order and I can't create it.

Hi @HoboCY ! Have you seen our developer documentation on order and fulfillment apps yet - it sounds like this might contain the information you're after?

Based on your description, it sounds like you're looking to build a fulfillment service app. If so, the developer documentation outlines the API call flow for how to build an app like this.

Hope this helps!
