@ChrisRahme Thank you very much for the informative reply. Currently, I am trying out with Postman.
I will attach a Screenshot of a single slot set that I was trying after seeing another forum post (Is there any way to set Slot by API not by action) which didn’t work out for me.
Here I have used only Content-type —> application/json headers
I have configured the endpoints.yml exactly as you stated above. and I am not using along with a Sender ID I just wanted to try out with the initial session created after the command Rasa Shell I am working on my college research project so I am using the Framework to work with the initial session.
If it is required to use sender ID will you please let me have an idea to work on my basic purpose?
