Is it possible to use a custom callbackUrl for OpenID Request?

[christoph-bittmann]

Question 💬

Hi there!

The redirect_uri parameter, which is part of request header, follows by default the pattern [BASE_URL]/api/auth/signin/[PROVIDER_ID] . Is there an option to define an custom redirect_uri for the authorization request.
( I don't wan't to know how to define a custom callBackURL ... ).

An simular question was asked here: #591 (comment), maybe this help to understand the context :)

How to reproduce ☕️

// [...nextauth].ts

`import NextAuth from "next-auth"
import { OAuthConfig } from "next-auth/providers"

const providerConfig: OAuthConfig & {
callbackUrl?: string
} = {
id: "spch",
name: "SP",
type: "oauth",
version: "2.0",
wellKnown:
"https://[...]/.well-known/openid-configuration",
callbackUrl: "http://localhost:4200/oauth2/callback",
authorization: {
params: {
scope: "openid customer ACR_Level_10 ACR_Level_20 ACR_Level_30",
redirect_uri: "http://localhost:4200/oauth2/callback",
clientId: "...",
codeChallengeMethod: "S256",
},
},
clientId: "swisspass_ch_entw",
idToken: true,
profile(profile) {
return {
id: profile.id,
name: profile.givenname,
email: profile.authenEmail,
}
},
}

export default NextAuth({
providers: [providerConfig],
callbacks: {
},
debug: true,
})`
