How to extract an interface ID?

How would I got about finding the interface id corresponding to a definition in a daml source file? I need this to exercise a choice on the JSON api.

I’ve tried daml damlc inspect, canton console, and navigator, but I haven’t had much luck so far.

So I found a rather silly but simple way to do this: I used the typescript code generation and then looked at the resulting source code.

All codegens include the package ID where necessary, and make it so you can exercise choices without referring to any string IDs directly. If your language doesn’t have a Daml codegen, you can use inspect-jar as mentioned here.
