https://lemmy.ml/api/v3 works for lemmy.ml, but when I try it with lemmy.world it gives bad request, any help?

hmm, interesting. It works when I do it in my node environment, but the moment the browser tries to make the request it fails.

The error message tells you why it failed

[โ€“] Yoru 1 points 1 year ago (1 children)

oh, it's because lemmy.world doesn't allow api requests from lemmy.ml, and vice-versa. Is it possible that there's a workaround?

Make a bot account on the other server

I'm making a bookmarklet to transfer followed communities from one instance to another

Whoever would be using that bookmarklet would need to have accounts on both instances.

that's not the issue unfortunately, websites usually don't allow api requests to be made from another website, I fixed it using this github repo

@[email protected] - it has to do with CORS (says in the error message) - You generally can't make cross-origin requests in the browser unless it is explicitly allowed. This is purely a browser limitation, which is why it works in your node environment. But if you open the console on any random website and try to call fetch() to that API, it's going to fail on any site other than lemmy.world.

yeah that's what I observed after a few more trying, is there a possible workaround to this?

[โ€“] nickel 3 points 1 year ago

Anything you do cross-origin will have to be done in a server-like environment instead of in the browser.
