+### 🚀 Production Setup
+
+When moving to production, ensure you:
+
+1. Create a [production API key](https://docs.crossmint.com/introduction/platform/api-keys/client-side)
+2. **Important**: Add your mobile app identifiers to the production API key:
+   - iOS: Bundle ID (e.g., `com.company.appname`)
+   - Android: Package name (e.g., `com.company.appname`)
+
+**Note**: Production requires mobile app identifier whitelisting, unlike staging. Make sure to complete this step to avoid request failures in production.
+
+See [Mobile App Identifiers documentation](https://docs.crossmint.com/introduction/platform/api-keys/client-side#mobile-app-identifiers) for complete setup instructions.
