Action POST request

how do you call actions. I tried the following :

 curl -d "etype=sum" -X POST http://localhost:5055/webhook
 curl -d '{"etype":"sum"}' -X POST http://localhost:5055/webhook

but getting error, what do I do wrong :

/btw the documentation is unclear how do you do actions. Nowhere is mentioned that you have to start a server i.e. rasa run actions … and how you can test it/

hi - the docs for the action server endpoint are here Action Server

i see … it seems too complicated to be able to generate it on the fly … hmm.
