Outbound Messages

▪ Allows you to specify that changes to fields within Salesforce can cause messages with field values to be sent to designated external servers.

▪ Outbound messaging is part of the workflow rule functionality in Salesforce. Workflow rules watch for specific kinds of field changes and trigger automatic Salesforce actions, such as sending email alerts, creating task records, or sending an outbound message.

Outbound Messages

▪ Originally created on the golden days of SOA▪ Defines a contract with WSDL▪ XML/SOAP based▪ Triggered by Workflow rules▪ Declarative friendly▪ Recommended method for outbound async process

integration (“Integration patterns overview”)▪ Used to implement the “Fire and Forget” pattern

Fire and Forget

▪ A DML update or insert occurs on a given set of records in Salesforce

▪ A Salesforce workflow rule triggers based on a given condition

▪ This rule invokes a pre-configured OM that sends a SOAP message to a remote listener

▪ The remote listener receives the SOAP, places in a local queue and return positive ACK.

▪ Salesforce receives the ACK and completes the request. (It waits 10 seconds, then a retry is sent up to 24hs)

▪ In case remote app needs to perform operations against Salesforce a SessionID is provided to implement a callback
