How do I get .pem file for push notification on iOS?

The old Simi Push Notification feature was deprecated from 01 Jan 2020. We've switched to OneSignal for push notification now. Please see this updated guide from OneSignal:

Step 1: Go to and login to your Apple Developer Account.

Step 2: Select Certificates, Identifiers, Profiles

Step 3: Select tab Certificates, then Click (+) to add a new Certificate

Step 4: On Select Type page, select Apple Push Notification service SSL (Sanbox & Production). Then click Continue

Step 5: On this page, select the App ID you want to push notification to. Then click Continue

Step 6: Go to Create a New Certificate

Step 7: Prepare on your Mac (or a computer running MacOS)

  • Open Spotlight search and search “keychain”.
  • Follow Keychain Access/ Certificate Assistant/ Request a Certificate from a Certificate Authority

You are directed to “Certificate Information”. Please fill out all required information: 

  • Your Apple account email as “User Email Address”
  • app_pushnotification as “Common Name”

Tick on “Saved to disk”. Next, save this file as “app_pushnotification” and then you will get . certSigningRequest file on your Desktop


Step 9: Come back to your account on You need to click “Choose file” to upload the app_pushnotification.certSigningRequest file you have just created. Then, click “Continue”.

Then click "Download".

Step 10: After that, double click on the file you have just downloaded, change file’s name as app_pushnotification.cer, move this file to your Desktop and open “Keychain Access”. Now find “app_pushnotification” and “Apple Push Services:<your App ID>” and export these 2 items. Then, save this file as “app_pushnotification” and move to your Desktop. Please note that the file format is (.p12)

Step 11: Generate PEM file


Open Terminal and execute the following steps:
Go to the folder where you downloaded the files, in this case it's the Desktop:

  1. cd ~/Desktop/
  2. openssl pkcs12 -in app_pushnotification.p12 -out app_pushnotification.pem -nodes –clcerts     <Note: You need to enter the password you created at Step 10>
  3. openssl x509 -in app_pushnotification.cer -inform der -out app_pushnotificationpass.pem
  4. cat app_pushnotificationpass.pem app_pushnotification.pem > app_pushnotification_end.pem

The file app_pushnotification_end.pem is the one you need.

Step 12: Go to your backend, SimiCart > Notifications > Notification Settings
(Magento 1.x: Simiconnector > Connector Settings > General Settings > Notification Settings)

Click Choose File at Upload Apple PEM file to upload the .pem file you've just created. Finally, click Save Config.
