Push Notifications settings

If you want to use promo campaigns, you will need to generate a certificate for sending push notifications. It takes several steps to generate and may take about 10 minutes.

Create a signing certificate

Open Keychain Access and on the upper menu choose Keychain Access > Certificate Assistant -> Request a Certificate From a Certificate Authority.

Enter your email and name and save the certificate to a disk. It'll be named like CertificateSigningRequest.certSigningRequest.

Create an Identity and Apple Certificate

Open Apple Developer and then Certificates > Identifiers.

Choose your identifier, activate Push Notifications, and hit Save.

Go to Certificates section and start new certificate generation

Scroll down and select Apple Push Notification service SSL (Sandbox & Production)

Choose your Identifier and upload a certificated generated on your Mac earlier

And download a certificate as aps.cer file.

Open the aps.cer file in the Keychain and export in as a p12 file.

Please be sure that you choose Certificate category! Otherwise you can't export it a p12 file.

The last thing, convert your p12 file to a plain text. Open terminal and enter a command

openssl pkcs12 -in cert.p12 -nodes > open_cert.p12 change cert.p12 to your file name.

And the last, upload a certificate to SubGrow.
