Hi is there any guidance on how I could make my own APM Client? I am attempting to create one for Haskell. I attempted to browse some of the existing implementations but they can be quite large. It also seems that some clients use special language features from the docs.

What version should I use of the spec should I use? [apm-server/docs/spec at main · elastic/apm-server · GitHub](https://github.com/elastic/apm-server/tree/main/docs/spec)

The [APM agent specs](https://github.com/elastic/apm/blob/main/specs/agents/README.md) is a good place to start for writing an Elastic APM client in your choice of language.

Another option to consider is OpenTelemetry, which Elastic APM can [ingest natively](https://www.elastic.co/guide/en/apm/guide/current/open-telemetry.html). A [quick search](https://duckduckgo.com/?q=opentelemetry+haskell&t=ha&va=j&ia=software) turned up a few projects providing a haskell client.
