Sending Notifications Using Webhooks and Slack
Starting with Enterprise Manager 13c Release 5 RU 15, using the EM Generic Webhook, you can send event and incident notifications to any application that accepts webhook requests and can parse payload specific content. The webhook payload format depends on the type of the event or incident. Users will have to provide the structure for the payload to map EM to the external software.
To access the Webhooks and Slack page navigate to the Setup drop-down menu, hover over Notifications and locate the Webhooks and Slack option.

To use Webhooks or Slack as a notification method, you must enable it through Incident Rules. When on the Add Actions page for an incident or an event rule, locate the Advanced Notifications section to enable your preferred notification method (e.g., Slack).
