Status query request message
With the BlackBerry® Push Plus package, you can request information about the status of a push message. The push message is identified by its push ID. You can receive information about the message on certain BlackBerry devices by specifying their PINs as addresses. If you do not specify the PINs, the system returns information about every BlackBerry device that receives the message with that push ID.
After it receives a status query request message, the PPG sends the Push Initiator a status query response message.
Status query requests are included with the BlackBerry Push Plus package. They are not available with the BlackBerry Push Essentials package.
