Getting APNS Tokens

With a Courier Mobile SDK

Using a Courier Mobile SDK is the best way to set this up. All Courier Mobile SDKs sync APNS tokens to Courier and will be automatically managed. This allows you to send pushes directly to a user_id rather than APNS tokens.

Mobile SDK	APNS Token Management	Tracking Analytics
iOS	Automatic	Automatic
Android	Not Supported	Not Supported
React Native	Automatic	Automatic
Flutter	Automatic	Automatic

Without a Courier Mobile SDK

Follow Apple's Documentation to setup push notifications on your iOS device.

Manual Implementation Requirements

You will need to sync, store, and manage your user's APNS tokens. This likely will require you to create entries in your database, deploy separate endpoints, and add extra development time that can be avoided with a Courier Mobile SDK.

If you'd like Courier delivery and click tracking, you will also need to manually make a request to the trackingUrl.

Sending Messages

This is a common example request you can make to the send api that shows:

1. providers.apn.override.body.aps.YOUR_CUSTOM_KEY for adding custom data to your payload. This is usually used for opening a specific screen in your app when the user takes action on a push notification.
2. providers.apn.override.body.aps for applying iOS specific values. You can learn more about these here.

Sending to a user_id (Recommended)

Automatic Courier Mobile SDK Formatting

By default, Courier automatically formats parts of the APNS payload to make a better developer experience for you if you are working with a Courier Mobile SDK. Here you can manage the automatic APNS settings.

What this setting does:

1. Creates a simple toggle to send to Apple's production or sandbox push notification environment. Production (switch is on) is used in your production app and Sandbox (switch is off) is used for testing and development. More Details
2. "Attach Mutable Content" supports Courier's iOS Notification Service Extension for better push notification delivery tracking.
