1) The document discusses configuring Salesforce push notifications in Mulesoft. It involves defining a push topic in Salesforce to watch for changes to the Account object, setting up the Salesforce cloud connector in Mule with authentication details, and creating an inbound endpoint in Mule subscribed to the push topic to receive notifications of changes from Salesforce. 2) When changes are made to any Account records in Salesforce, the defined push topic will send a notification to the subscribed Mule flow. 3) The flow will log any payloads received from the Salesforce notifications to demonstrate receiving real-time updates of changes made in Salesforce.

1. Push Notification Salesforce
in Mule

2. 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.

3. Mule SFDC Cloud Connector
Select the MULE SFDC Cloud Connector and setup the following
details by defining the Global element –
 User Name
 Password
 Security Token
 URL

<sfdc:config name="Salesforce"
username="test@test.com"
password="test"
securityToken="DbdkalteklajdcvNJ2vx0
LBHDpYw" url="https://test--
test.cs8.my.salesforce.com/services/
Soap/u/23.0" doc:name="Salesforce"/>

4. Mule SFDC Inbound Endpoint
To receive the Push Topic notifications from Salesforce, Salesforce
connector has to define as a inbound endpoint with the ‘Subscribe
topic’ operation by including the Push Topic Name –

<sfdc:config name="Salesforce"
username="test@test.com" pass-
word="test" securityTo-
ken="dsggasgLtcvNJ2adsfDpYw"
url="https://test--
test.cs8.my.salesforce.com/services/So
ap/u/23.0" doc:name="Salesforce"/>
<flow name="SFDC_TopicFlow1"
doc:name="SFDC_TopicFlow1">
<sfdc:subscribe-topic config-
ref="Salesforce" top-
ic="/pushTopicForAccount"
doc:name="Salesforce (Streaming)"/>
<logger message="****** SFDC :
#[payload]" level="INFO"
doc:name="Logger"/>
</flow>

5. 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 -

6. 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 -
