@axw I wanted to keep the endpoints local to the lambda module. In the agent config I see that we have option for multiple APM server URLs so I am not sure what is the best way to get the base URI (I think it would always be localhost:8200 but hard coding like this is probably not the best idea)

Hmm, I'm not sure what the best approach is here. Since it's a special case, I also wouldn't want to complicate the main API.
ELASTIC_APM_SERVER_URLS (multiple URLs) is deprecated, and I think the only time you would set a non-default URL is for testing purposes. So I'd say just use os.Getenv("ELASTIC_APM_SERVER_URL") here, and default to http://localhost:8200.

@lahsivjar thanks, I think this turned out pretty well. We could neaten it up a bit if we want to go ahead with it, but I think it's proven the approach can work.

I don't love exposing this just for Lambda. td.Context.build() mutates the transaction context, for one thing. I think it's okay as it is, but could be a source of bugs later down the line.
Maybe we could have a method which only copies immutable properties (IDs, sampled status, sample rate) to the model object? Or otherwise, perhaps we could expose those properties as methods on Transaction, and build the partial transaction model directly in module/apmlambda code. Would that be awful?

Register the transaction with lambda extension to handle unexpected failures and crashes. In these unexpected cases, the lambda extension will create a proxy transaction on behalf of the agent.
Closes: #1323
