"Redirect URI match failed"

I’m working on a new marketplace app and I’m getting the error msg above since today when switching from localhost which works fine to the real redirect url.
Any pointers in what to do? It used to work yesterday and I don’t think anything changed on my end since then. Probably a temporary issue?

Ok, answering my own question :slight_smile:
When changing the redirect URL and starting the auth flow from the sandbox by installing the app, I’m running into the given error.
To fix it:

  • Change the callback URL in the marketplace listing
  • Start the auth flow from your app instead of trying to install it from the marketplace sandbox
  • Once the auth flow has worked one time starting from your app it also seems to work from the marketplace sandbox install
