LINE Login → Return to Bubble Native App (OAuth / Deep Link Flow)

Need help APIs
1

I’m trying to implement a login flow in a Bubble native mobile app (BDK / Bubble Native).

What I want is very simple:

  • Open the LINE app (or LINE login flow) from my Bubble app

  • Let the user log in with LINE

  • Return the user back to my Bubble app after authentication

I do NOT necessarily need the LINE SDK specifically. A web-based OAuth flow is also fine if it can return the user back into the app afterward.

Has anyone successfully implemented something like this with:

  • OAuth

  • redirect URLs

  • custom URL schemes

  • universal links

  • Bubble API Connector

  • Bubble Native / BDK

Mainly I want to know:

  1. Is this flow realistically possible in Bubble Native today?

  2. Can the app return correctly after authentication?

  3. Does the login usually happen in the LINE app itself, or only in a browser/webview?

  4. What is the recommended architecture for this?

Any examples, plugin suggestions, or implementation patterns would be greatly appreciated.

Thank you!
