App Store Connect setup

Register your App ID, enable capabilities, create an ASC API key, and prepare for iOS production builds.

Showing IDs from your app

Prerequisites

Apple ID with Two-Factor Authentication
Active Apple Developer Program membership ($99/year)

1. Register your App ID

Open Certificates, Identifiers & Profiles
Create an App ID with an Explicit Bundle ID matching com.example.app
Enable capabilities as needed: Associated Domains (website URL), App Groups + Push Notifications (OneSignal)

2. Associated Domains

When your app has a website URL, the iOS build injects Universal Links for:

applinks:example.com
applinks:www.example.com

Enable Associated Domains on App ID com.example.app in the Apple portal, then rebuild so profiles regenerate.

3. App Group (required if OneSignal is enabled)

Create App Group identifier group.com.example.app.onesignal and assign it to both:

Main app: com.example.app
Notification Service Extension: com.example.app.OneSignalNotificationServiceExtension

Register groups at Apple Developer → App Groups. See the OneSignal guide for the full checklist.

4. Create the app on App Store Connect

Go to App Store Connect → Apps
New App → select Bundle ID com.example.app

5. Create an App Store Connect API key

Open Users and Access → Integrations → App Store Connect API
Generate a key with Admin access
Copy Issuer ID, Key ID, Team ID, and download the .p8 file (once only)
Paste them into WebsiteTo.app → Configure → iOS
