Apple push notification service for MDM

Question

I've read a tutorial about Apple push notification here

Due to it, I have to provide App Id to identify which application will receive the notification. In case of MDM server, the receiver is built-in client, so what value I have to put in field "App Id" when I register for SSL certificate

on another question I've post, I was answered that in case of MDM, the field "Topic" is used for built-in client to receive the notification. Topic is put in MDM payload that server sent to client. So how server register this field with APNS

Thank all,

1) You don't go through usual push certificate creation route.

What you do is following

• You create a CSR for APNS request signging certificate
• You send it to Apple and Apple will sign it, so you will have APNS request signing certificate
• Each custom will create APNS CSR and send it to you
• You will sign it with APNS request signing certificate
• You will return this APNS CSR to the customer
• The customer will upload it to Apple
• Apple will sign it
• Now, the customer has APNS certificate
• The customer uploads it to the MDM server

All of these is described in a lengthy details in MDM protocol documentaion.

2)Here is how topic is shared between a client and the server

• APNS certificate signed by apple will have a topic in it (in UID part of DN)
• Your MDM server should extract it from APNS certificate and put it in MDM payload.
• This payload will be delievered to a device and OS will send it to buil-it client
• Now, both your server and built-in client know the shared topic.
