How to create and get a custom fulfillerId?

I’m trying to make the “fulfilled by” field customizable when creating a product. I checked the Wix documentation but didn’t find an API endpoint to create it. Then I tried passing my app ID in fulfillerId, but it still didn’t work. I have no idea how to handle this issue and would greatly appreciate any help.

I want to know how I can create and obtain this fulfillerId.:smiling_face_with_tear:

Can you share which docs this is for? It’s hard to tell/be able to advise without knowing which docs you are trying to use.

Thank you for your help!

I found that field in this doc

You can find it at “productphysicalPropertiesfulfillerId"

The fulfiller id can be your app id (not app instance id). the order contains product with that fulfiller id will be able to submit fulfillment tracking info

Thank you for your reply.

I have tried passing in the app_id multiple times, but it still hasn’t taken effect. Do I need any other configurations?
