To send push notifications to iOS devices, you'll need to get an authentication key from Apple. This needs to be done from the Apple Developer account where the app will be published from, which in most cases means the financial institution client's account.

Getting your key

1. Navigate to https://developer.apple.com/account
2. Select Keys under Certificates, IDs & Profiles
3. Click the "Plus Sign" to add the new key
4. Give your key a name
5. Check the box for Apple Push Notifications service (APNs)
6. Click Continue and then Register to confirm the new key
7. Download your key
8. Store the key in a safe location and share it with the nudge team along with your Apple Team ID. We'll use it to activate your account!

• You can find your Team ID in the Membership details section of your Apple Developer Account page
