Missing ibi (iOS bundle ID) parameter on generated email link authentication URLs

[jesuslosada]

Describe your environment

• Operating System version: Ubuntu 22.04
• Firebase SDK version: 6.2.0
• Firebase Product: auth
• Python version: 3.11
• Pip version: 23.2.1

Describe the problem

The URLs generated by firebase_admin.auth.generate_sign_in_with_email_link() include the relevant Android parameters (apn - Android package name, amv - Android minimum version) but the iOS bundle ID passed through ActionCodeSettings.ios_bundle_id is ignored and there is no ibi parameter in the resulting URL.

Steps to reproduce:

1. Initialize a firebase_admin.auth.ActionCodeSettings object assigning a ios_bundle_id value.
2. Generate an email link authentication URL by calling firebase_admin.auth.generate_sign_in_with_email_link() with the previously generated ActionCodeSettings.

The parameter named currently used by firebase-admin is iosBundleId (see

firebase-admin-python/firebase_admin/_user_mgt.py

Line 543 in aef52be

parameters['iosBundleId'] = settings.ios_bundle_id

), while the expected name is iOSBundleId according to the documentation here: https://cloud.google.com/identity-platform/docs/reference/rest/v1/projects.accounts/sendOobCode

Relevant Code:

import firebase_admin
import firebase_admin.auth


firebase_admin.initialize_app()


def main():
    action_code_settings = firebase_admin.auth.ActionCodeSettings(
        url="https://example.firebaseapp.com/email-link-test",
        handle_code_in_app=True,
        ios_bundle_id="your.app.bundle",
        android_package_name="your.app.package",
        android_install_app=True,
        android_minimum_version="1",
        dynamic_link_domain="example.page.link",
    )
    email = "example@example.com"
    link = firebase_admin.auth.generate_sign_in_with_email_link(
        email, action_code_settings
    )
    print(link)


if __name__ == "__main__":
    main()
