Generate an iOS Push Certificate

A step-by-step guide to create an iOS(APNS) Push Certificate.

📘

For iOS Apps, not websites

This guide is for developers implementing iZooto in an iOS application for distribution on Apple's App Store. This guide should not be used for Web Push.

An iOS Push Certificate is required for notification delivery to all iOS apps.

Step 1 - Requirements


Step 2 - Provisioning

2.1 Generate Certificate Request File

Open the Keychain Access app on your Mac OS X system. By default, it will be located in Applications > Utilities > Keychain Access.

Select Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority.

775775

Next, select the Save to disk option and enter your information in the required fields. This creates a certification request file that will be used later.

2.2 Add iZooto Identifier

Select your Identifier in your Apple Developer Account under Certificates, Identifiers & Profiles > Identifiers

10631063

Scroll down to the bottom and enable Push Notifications for your identifier.

976976

Next, go to Certificates and create a new certificate by clicking the blue + (plus) button.

Under Services, select Apple Push Notification service SSL (Sandbox & Production) and click Continue.

The certificate will be applicable to both Sandbox and Production environments, so you do not need a separate key for each one.

Choose an App ID from the App ID pop-up menu, and click Continue.

808808

Click Choose File, select the CertSigningRequest file you saved in the first step, click Open, and then click Continue.

11571157

Click Download to save the certificate to your computer.

2.3 Creating a Private Key

Open the .cer file you downloaded in the last step by double-clicking on it in Finder.

852852

After a few seconds, the Keychain Access program should open. Select Login > My Certificates, then right-click on your key in the list and select Export.

989989

Give the file a unique name using the .p12 extension, and click Save. You will have an option to protect the file with a password.

2.4 Converstion to .pem

Navigate to your certificate directory in the terminal and execute the following command.

openssl pkcs12 -in YOUR_CERTIFICATE_NAME.p12 - out YOUR_CERTIFICATE_NAME.pem -nodes

You will now have a cert.pem and cert.p12 file.


Step 3 - Configure your iOS App with iZooto

Once you have the APNS .p12 certificate, proceed to add your iOS app to your iZooto account.

👍

Done!

You now have a certificate to send push notifications from your iOS app.

If you have not already done so, proceed to install the iZooto SDK in your app.
