GitHub App - redirect_uri is not recognized

Body

I'm following a guide here and added multiple callback URLs to my application.
They differ by parameters and look like
https://myserver.io/api/github/v1/oauth2/callback
https://myserver.io/api/github/v1/oauth2/callback?case_one=value_one
https://myserver.io/api/github/v1/oauth2/callback?case_two=value_two

But when I'm using https://github.com/apps/my-git-hub-app-name/installations/new?redirect_uri=https%3A%2F%2Fmyserver.io%2Fapi%2Fgithub%2Fv1%2Foauth2%2Fcallback%3Fcase_two%3Dvalue_two link This redirect URL is not selected - it uses the default first one.

We're also facing the same issue, it looks like this has been broken for months now. It's pretty annoying since we have multiple URLs setup for different testing environments and it only ever selects the first one. I've tried everything, triple checked the redirect_uri is being encoded correctly. Nothing works.

Same problem, I had this problem at least a year ago, I had to create a new github app for each environment. I tried again today, but still no solution. What rubbish

From my understanding the install link https://github.com/apps/APP-NAME/installations/new doesn't support the redirect_uri parameter. It only supports the state parameter as described in the Sharing your GitHub app via install link documentation.

The redirect_uri parameter seems to be supported only when using the authorize URL https://github.com/login/oauth/authorize or when generating an access token using https://github.com/login/oauth/access_token, described in the Generating a user access token section.
From the docs:

If you want to control which callback URL is used, do not select Request user authorization (OAuth) during installation. Instead, direct users through the full web application flow and specify the redirect_uri parameter.

It would be really nice if the install link also supported the redirect_uri parameter.

Is there any update on this, or any workaround on how the redirect_uri could be applied on the installation ?

Seems like its still an issue 🤔

Redirect uris are supported, I think you are missing this part:

The redirect_uri parameter is optional. If left out, GitHub will redirect users to the callback URL configured in the OAuth app settings. If provided, the redirect URL's host (excluding sub-domains) and port must exactly match the callback URL. The redirect URL's path must reference a subdirectory of the callback URL.

Any update on this?
Could you please clarify the flow?
Can we use a custom redirect_uri as a callback in the GitHub App installation flow?
It seems like it’s being ignored.
