The document provides a guide on setting up Salesforce Push Topics in Mule ESB to receive notifications for changes made to the Salesforce account object. It explains using the Developer Console to create a push topic and configuring the Mule SFDC cloud connector and inbound endpoint to subscribe to these notifications. When changes are made in Salesforce, such as updating account details, Mule will receive real-time notifications via the streaming API.

Define Push Topic in SFDC
The easiest way to do this is to either use the workbench at developerforce.com or the developer
console. I'm going to use the developer console. In the console head to Debug -> Execute
Anonymous Apex Code. We are essentially creating a SOQL query with a few extra parameters
that watch for changes in a specified object.
If the Push Topic is executed successfully then Salesforce is ready to post notification to MULE ESB
if any changes made in the Account object in Salesforce, because the below Push Topic has been
created for Salesforce’s Account object.

Mule flow
Salesforce connector is defined as an inbound endpoint with the ‘Subscribe topic’ operation by
including the Push Topic Name. In case of any changes in the Salesforce Account object, the Push
Topic defined in the Salesforce will auto post the notification to the Mule Connector. Once the
Account changes received in the flow -

Outcomes
After deployment of the Mule project, if any changes made against the Account object then it will
be notified to Mule using Streaming API.
For example, I have made changes in the Customer details for Last Name from ‘Pandey’ to
‘Pandey1’ –
Once the changes are saved in the Salesforce, this will be notified to Mule via Push Topic -
