How to enable outbound message for a Salesforce org?

Hi,

To define outbound messages in a Salesforce Org, use this procedure in the Salesforce user interface:

1. From Setup, enter Outbound Messages in the Quick Find box, then select Outbound Messages.
   Click New Outbound Message.
2. Choose the object that has the information you want included in the outbound message, and click Next.
3. Configure the outbound message.Enter a name and description for this outbound message.
4. Enter an endpoint URL for the recipient of the message. Salesforce sends a SOAP message to this endpoint. For security reasons, Salesforce restricts the outbound ports you can specify to one of the following:

   80: This port only accepts HTTP connections.
   443: This port only accepts HTTPS connections.
   1024–66535 (inclusive): These ports accept HTTP or HTTPS connections.

5. Select the Salesforce user to use when sending the message by specifying a username in the User to send as field. The chosen user controls data visibility for the message that is sent to the endpoint.
6. Select Include Session ID if you want a sessionId to be included in the outbound message. Include the sessionId in your message if you intend to make API calls back to Salesforce from your listener.
7. The sessionId represents the user defined in the previous step and not the user who triggered the workflow.
8. Select the fields you want to be included in the outbound message and click Add.
9. Click Save, and review the outbound message detail page.

I hope these steps help you.
