Roblox has updated the requirements for the UGC program and for group owned items, the group owner has to be subscribed to premium 1000/2000.
As for the error you see in the console, HTTP status 403 means forbidden and the response you see when you visit the API URL is a 405 response which means you cannot interact with the API using that method, specifically GET which is what browsers use when visiting URLs. You may get more information if you try calling that API endpoint using the appropriate method (which most likely is POST) with a program like postman.
Unfortunately you cannot put UGC on-sale that was by a kicked member, you should post this in #feature-requests. (I so would because I have this problem but devforum level up is impossible)
This is a mutation of the original code that you’d input on the website’s console to change avatar pose, though made to use the on-sale endpoint. I’m not sure if its against the rules to put something like this here, but I attempted to use the publish API, doesn’t seem to work for me. I found the specific endpoint on this post.
intresting… it didnt say u have to have id verifiacition to put on sale items, it said its not required for group owners? idk who they ment as “publishing user” but it def didnt say that you need id on the creator dashboard
I’m pretty sure it requires you to have an ID Verified to access UGC in the first place, which I believe would be a hint to many if they attempt to configure UGC.
This is a bug-reporting update, attempting to on-sale UGC that’s by a kicked creator will return an error familiar with recognizing the server understanding the request but refusing to authorize it, meaning its intentional.
Feature Requests are later, but this isn’t a release announcement for that, more like a promise.
