How to renew a Push Notification Services certificate

Question

I am new to iOS development and, frankly, know little about certificates, with the exception of the part that they are necessary for publishing the application in the Apple store.

My company has several apps on the Apple Store, and I received an email: "Your Apple Push notification service certificate expires in 30 days." For one of the applications.

Now I'm not sure how to renew this certificate.

Here is what I did ...

• I logged in to developer.apple.com
• Went on certificates, identifiers and profiles
• The located application in which I received a message for

And now I'm not sure what to do.

See the screenshot below to see where I ended up.

And from here .. What should I do?

The certificate is not over yet, so can I renew it right now? or should I wait for its expiration? If I can do it right now, what should I do? Click "Create Certificate" and create a new one? How to do it?

Answer 1

Just generate a new certificate and replace the old one.

As a note: when your existing APNS certificate has expired, if your server is still using it, existing iOS applications will not be able to receive notifications from your server. But as soon as you renew the certificate and upgrade your server in order to use it, everything will be fine, without any changes in already installed applications.
