Message structure

According to the PAP standard, WAP-247-PAP-20010429-a, a push message has three parts:



RFC 2822 email message

This component contains the entire message. The RFC specifies the format of an email message on the BlackBerry® device. The address is the destination URL you received on registration, to port 80 for HTTP and to port 443 for HTTPS.

RFC 2045 MIME section

This component is a MIME attachment of type application/xml. Push messages that you send are always part of a multipart MIME message.

XML command

This component is an XML command. Standard xml commands contain <pap> top-level elements and nonstandard XML commands contain <bpds> top-level elements. For information about the XML commands, see the XML element reference.

Any other message or a response is sent as an XML message in an HTTPS response.
