Once you install the Slack App in your account, you can use automation rules to push messages to Slack for new tickets or ticket updates. Here's how you can set it up.
Login to your Freshdesk account as an administrator.
Navigate to Admin from the menu. Select Workflows and click on Automations.
Choose the Tickets tab and under Ticket Creation or Ticket Updates, click on the New Rule button.
Give your rule a name.
Enter the ticket properties and triggering events or conditions for which the automation should be executed.
For the Perform these actions: section, select Push to Slack option from the dropdown, and then select the appropriate Slack channel in the Push to dropdown.
Enter your message under the Message block. You can customize the message with dynamic content using Insert Placeholder option.
Click on Preview and Save, and then Save and enable.
