How to get the chatter update of case creation from Desk.com to Salesforce org?

Hi Himanshu,

Create Chatter Rules

• If you'd like to push cases to your Chatter Feed, here is how to do it:
• Create a new rule of any Event Type
• Define your rule criteria
• Choose Execute Webhook > SalesForce Chatter as the rule action
• Specify the Chatter Message you want to send (You may merge information from the Desk.com case using Liquid Variables)

Hope this helps you.
