I want to call GET and POST webservices from my custom action how can i do that ? Any help would be really appreciated. I am using rasa core 0.12.4 and rasa nlu 0.13.8

Did you already took a look at our documentation about Actions? Apart from that you may want to look at our example restaurant bot (rasa/examples/restaurantbot at master ¡ RasaHQ/rasa ¡ GitHub). The restaurant bot does not call any other service in the end, but in the actions.py file it defines a RestaurantAPI class (rasa/actions.py at master ¡ RasaHQ/rasa ¡ GitHub), which could execute some API calls to other services. Does that help?

Yes, you can basically write any code you want in your custom actions.

Hey were you able to successfully use requests library?

8

I am calling api in custom action, calling it using requests library raises " requests.exceptions.ConnectionError: (‘Connection aborted.’, RemoteDisconnected(‘Remote end closed connection without response’,))" inside the action server. but when calling the API outside the action server using the same code it responds properly!, any help?

I’m encountering the same trouble, did you get it fixed

I am facing the same issue when two concurrent conversations/users try to call API. Only second user got the response. for the first user “requests.exceptions.ConnectionError: (‘Connection aborted.’, RemoteDisconnected(‘Remote end closed connection without response’,))” Got this Error.

Do I have to use any asychronous model for calling the API instead requests?

If yes, help me how to do this?

Please help me resolve this.
