Applications can submit MMS messages to the Now SMS/MMS Gateway via any of the following protocols, which are described below:

• Now SMS/MMS Proprietary URL Submission via HTTP GET or POST
• MM7 - The MMS standard for applications to submit MMS messages to an MMSC. MM7 is an XML/SOAP based API where the MMS message is formatted in a MIME encoded XML document and posted to the server using an HTTP POST.
• MM4- The MMS standard for connectivity between multiple MMSCs. MM4 is an SMTP based interface where the MMS message is posted to the server as a standard MIME encoded e-mail message. While the interface exists primarily for connectivity between multiple MMSCs, the Now SMS/MMS Gateway also makes this interface available to application developers that are more comfortable with the SMTP protocol.
• MM1- The MMS standard for phones to send and receive MMS messages from an MMSC. This is an HTTP based protocol where applications can submit binary encoded MMS messages encoding according to the MMS Encapsulation Specification (application/vnd.wap.mms-message MIME type) to the gateway using HTTP POST.
• EAIF- This is a Nokia proprietary variation on the MM1 protocol which was defined as an interface for submitting messages to a Nokia MMSC. The interface is functionally similar to MM1, with additional HTTP headers defined.
