Messages Using Different Protocols

Message contents delivered to endpoints using different protocols may differ.

• Email or HTTP/HTTPS endpoints will receive the message subject, content, and a link to unsubscribe.

• SMS endpoints receive only the message content.

• FunctionGraph (function) messages contain the message attributes, subject, content, and topic URN. Table 1 describes parameters in FunctionGraph (function) messages. The following is an example message:

  {
     "record": [{
         "event_version": "1.0",
         "smn": {
             "message_attributes": "",
             "subject": "Welcome",
             "message_id": "e6fa59c6b3e0424c9c02cbed35b680e7",
             "topic_urn": "urn:smn:regionId:66e0f4622d6f4e3fb2db2e495298a61a:smn_123",
             "type": "notification",
             "message": "Hello",
             "timestamp": "2017-08-17T10:07:14Z"                             },
         "event_source": "smn",
         "event_subscription_urn": "urn:cff:regionId:66e0f4622d6f4e3fb2db2e495298a61a:function:DEFAULT:mytest:latest"
         }]
  }
