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" }] }
