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.
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
