Create an EventBridge Rule for Logging Events in a CloudWatch Log

To test the connection between Salesforce and AWS and ensure that the event messages are received in EventBridge, add a CloudWatch log as a target of a rule. Incoming event messages from Salesforce are logged in CloudWatch.

1. In Amazon Eventbridge, click Rules.
2. Select your event bus from the dropdown. The name of the event bus is the same as the name of the partner event source that you queried earlier. It’s in this format: aws.partner/salesforce.com/orgID/channelID
3. In the Rules section, click Create rule.
4. Provide a name for your rule.
5. Click Next.
6. Under Event source, select AWS events or EventBridge partner events.
7. Skip the Sample event section. In Event pattern, for Event source, select EventBridge partners.
   1. From the partner dropdown, select Salesforce.
   2. For Event type, select All Events. The event pattern box autopopulates to this value.

      {
        "source": [{
          "prefix": "aws.partner/salesforce.com"
        }]
      }

8. The rule matches incoming events based on the defined pattern. If you want to add a filter to match a specific platform event, match events whose detail-type field contains the API name of the platform event, for example, Carbon_Comparison__e. For more information about event pattern matching, see Content filtering in Amazon EventBridge event patterns in the AWS documentation.
   1. Under Event pattern, click Custom patterns (JSON editor).
   2. In the input box, In Define pattern, select Custom pattern, and replace the pattern with this pattern.

      {
        "source": [{
          "prefix": "aws.partner/salesforce.com"
        }],
        "detail-type": ["Carbon_Comparison__e"]
      }

9. Click Next.
10. Under Target 1, Target types, select AWS service.
11. Under Select a target, select CloudWatch log group.
12. Complete the log group path. For example: /aws/events/mygroup/log.
13. Click Next and then Next.
14. Review the rule that you created, and then click Create rule.
