Can I trigger PagerDuty Incident with SNS only?

Question

I'm trying to get paged in pagerduty when a new object is created in my S3 bucket with prefix 'invalid-files/'. I've created a NotificationConfiguration for S3 that publish to my SNS topic. I also have a cloudwatch integration and I tried to use that URL to subscribe to my topic but it didn't work. It seems the event has to maintain a schema otherwise PD won't trigger any incident.

Few alternative I found but I'm looking for something better.

• Custom Event Transformer do the job but we are using PagerDuty terraform provider to maintain PD. And seems like Custom Event Transformer is not available in terraform provider.
• I can use SQS instead of SNS for the S3 NotificationConfiguration and then consume the message from a lambda and do something about it. but it feels like a overkill for getting a notification for object creation.
• I can set alarm on the SQS without the lambda, but then I have to purge the queue everytime I get an alarm.

Is there a simple idea that I can use to trigger PD incident for S3 object creation?

Another option could be an App Event Transformer -- you won't be able to terraform the App metadata, but once you have the app ID (still called a vendor_id in the service/integration endpoints), you should be able to terraform your services with that, and avoid duplicating the custom event transform across multiple services.
