I'm using Expo to get started with an app which authenticates with Azure AD Oauth as per: https://docs.expo.dev/guides/authentication/#azure

It works with a single redirect URL exp://host:port with Expo Go.

However, when I build the app, I simply change the redirectURL to the bundle id e.g. com.xyx.poc . . .I really don't know what redirect URL to set in the Azure Portal (app registrations) . . . .

Do I use a web redirect URL or a iOS / Android platform redirect URl? And what value do I set it to? I've tried a tonne of things e.g.

msauth://code/msauth.com.xyz.poc%3A%2F%2Fauth
msauth.com.xyz.poc://auth
msauth.com.xyz.poc

Please help. . . . I just need to know what to set up in app.json / relevant tsx where the auth component lies and what to set up in the Azure Portal / App Registrations section for redirect URL. . .

  • Hi, I've already had it working with Expo Go, but not once the Expo app is compiled to APK / iPA. . . . I quite honestly have run out of ideas on what to put as redirect URL on the Azure Portal in the Authentication settings redirect URLs. . . . – ISDr Dec 14 '22 at 14:48
  • If I use ://auth as the redirect URL, and put it as a redirect URL in Azure, expo sends it to azure with extra :// WHICH IS WRONG!!!!! . . . . How do I prevent expo from adding extra :// e.g. ://auth:// . . . . . . . . – ISDr Dec 15 '22 at 11:11

I managed to figure this out after over a day of tweaking and reading. Wish it was clearer, but here goes:

I set the redirect_uri as follows:

redirect_uri: makeRedirectUri({ scheme: '<bundle_id_here>', path: 'auth' }),

My expo.scheme was set to just: "<bundle_id_here>"

In Azure, under App Registrations, Authentication, I put in a "web and desktop application" redirect URL as: <bundle_id_here>://auth

Create web app then update inside redirect url.

Please update your redirect url inside manifest it allow @, https://auth.expo.io/@username/app-slug

The same url you can use using manifest inside AZURE left side menu bellow authorization, directly update your url.

I had same issue while update direct url into redirect url, so use manifest tab
