Creating an Event Notifications topic

You can send notifications or alerts to multiple destination types, for example, email, SMS, and others that are subscribed to a particular topic. Configure topics as needed and Event Notifications handles the routing and delivering of alerts reliably to the correct destinations.

Creating a topic

Select Topics in the Event Notifications console.
Click Create, and enter the following topic details:
- Name: enter a name for the topic.
- Description: add an optional description for the topic.
- Source: select a source from the list.
Step 1 created a topic, step 2 provisions optional custom rules for the topic.
Add the following rules to your topic:
- Event type: select event type from the list.
- Event subtype: select event sub type from the event sub type list.
- Severity: select severity from the severity list.
- Advanced conditions: create your own custom conditions, which must follow JSONpath specifications. The correctly written rule will extract the appropriate data from the incoming request payload. Event Notifications supports the == operator for JSONPath evaluation. You can validate your JSONPath here.
  
  Example:
```
{
   "data": {
      "findings": [
         {
            "severity": "LOW",
            "provider": "cert-mgr"
         },
         {
            "severity": "HIGH",
            "provider": "secrets-mgr"
         }
      ],
      "severity": "LOW",
      "payloadType": "findings",
      "issuer": "IBM Cloud Security Advisor",
   }
}
```
  Based on the previous JSON input, the following valid JSONPaths can be constructed:
```
1. $.data.severity=='LOW'
Output: True

2. $.data.findings[1].severity == 'HIGH'
Output: True
```
Click Add a condition.

If you do not select any rules, a default rule is added, which means all notifications route to the topic by default.
Click Create in the topic wizard.
