.p12 Certificate

Setup
  • To do the setup of remote push notification service you will need to setup one of the below thing.

Step 1. Requirements

  • An iOS mobile app. (This is not for websites / web push)
  • An Apple Developer Account with Admin Role.
  • A Mac computer with Xcode 11+
  • Your Xcode project should have the Push Notification capability added. Otherwise your project may not be shown in the Apple Developer Center.

Step 2. Identifier/ Provisioning

๐Ÿšง Deprecated Provisionator.
We have deprecated the Provisionator tool and recommend updating your application to instead use a .p8 token to connect to APNs.
If you would still like to use the .p12 certificate, you can continue following this guide to generate your certificate.
  • If you are renewing a certificate or your app already has an existing App ID or Provisioning Profile, skip to Step 3. Generate a Push Certificate.
  • If your App does not have an existing App ID or Provisioning Profile setup, then login to your Apple Developer Account and navigate to Certificates, Identifiers & Profiles->Identifiers and select the Blue + button.
  • Select App IDs and Continue
  • Select App and Continue
  • Provide a "Description" and your Explicit "Bundle ID". This must be the same as the "Bundle Identifier" you set for your project in Xcode.
  • Press Continue and on the next page, select Register

Step 3. Generate a Push Certificate

๐Ÿšง Previous Certificate Revocation
Previous .p12 Push Certificates for this Bundle ID will be revoked and cannot be used once you generate a new certificate with this method.

Request a Certificate From a Certificate Authority

  • Open the Keychain Access App on your macOS system. It may be located in Applications > Utilities > Keychain Access
  • Select Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority...
  • Next, select the Saved to disk option and enter your information in the required fields. Then click Continue.
  • This creates a certification request file that will be used later.

Add Capabilities

  • In your Apple Developer Account under Certificates, IDs & Profiles > Identifiers, select Identifiers.
  • Find and select your Identifier to enable Push Notifications, but do not click Configure.
  • If you do not see your Identifier, follow Step 2. Identifier/ Provisioning.

Select Push Notification Certificate

  • 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.

Select your App

  • Choose your App ID with matching Bundle ID from the App ID pop-up menu, and click Continue.

Upload your Certificate Signing Request

  • Click Choose File.., select the CertSigningRequest file you saved, click Open, and then click Continue.
  • Click Download to save the certificate to your computer.

Creating a Private Key

  • Open the .cer file you downloaded in the last step by double-clicking on it in Finder.
  • After a few seconds, the Keychain Access program should open. Select Login > My Certificates, then right-click on your Apple Push Services key in the list and select Export "Apple Push Services...".
  • Give the file a unique name using the .p12 extension, and click Save. You will have the option to protect the file with a password.

Step 4. Provisioning Profiles

  • Skip if selected "Automatically manage signing" in Xcode.
  • If you did not select "Automatically manage signing", then follow these steps.

Create Your Profile

  • Go to your Apple Developer Account > Certificates, Identifiers & Profiles > Profiles.
  • Next find any that are for your app and remove them if they do not have App Groups and Push Notifications in Enabled Capabilities:
  • Create a Profile by pressing the "+" button
  • Select the type of profile you need to create and press Continue.
  • Select the Development or Distribution Certificate to associate with the Profile. Then click Continue.
  • Name your Provisioning Profile.
Best Practices
When creating a new profile, make sure to enter a unique name in the "Provisioning Profile Name:" field. For example, if you are creating an Ad-Hoc Provisioning Profile to test push notifications with a Production Push Certificate .p12 file. Use the format AppName_AdHoc so you know the app and type of profile that it is.
  • Select Generate.
  • On the last page Download your profile.
  • Re-sync your Developer Account in Xcode by going to Xcode > Preferences... then click on the "View Details..." button. Then, click the refresh button on the bottom left of the popup. See Apple's documentation for more detailed instructions.
  • Make sure you pick your new provisioning profile from Build Settings>Code Signing>Provisioning Profile in Xcode.
