Extending REST API for administration purpose

Hello,

I discovered Rasa Stack a few days ago and I’m currently thinking about the best way of managing a production rasa-stack. The end users won’t be developers and therefore will need a very simple UI with no shell commands. We are planning to develop such an UI and we would need more HTTP endpoints for common use cases (e.g. training a model and downloading it through REST endpoint, gathering metrics about the rasa-core usage…). Do you plan to add such endpoints anytime soon or should I work on it and if I do so, what’s the best way to do this ?

Thanks for your help, Jean-Yves

update: I found the POST /jobs endpoint which is one of the endpoints I was looking for.

update2: I can’t find a way to make it work :confounded: Has somebody already managed to use this endpoint ? The example doesn’t work either

Here’s the data I’m trying to send over HTTP:

and the rasa core logs :
