Creating EventSource from REST API
There currently doesn't appear to be a way to create an eventsource through the REST API. This functionality would be very useful as part of an CI/CD pipeline.

It's part of a larger Infrastructure as Code philosophy. As part of developing a service, the relevant monitoring conditions may change/be expanded upon. Being able to roll out custom EventSources as part of a deploy helps keep everything in sync (i.e. when you deploy a version that has new error messages, you also deploy monitors for those error messages).
