Hi Malaisamy,

Most likely there is an error in your json payload:

{

"input":{

"text":"Radio"

},

"context":Hi <-- here Hi should be put into quotes

}

400 is a credentials issue i believe.   So it's probably an issue with the account details you have in SN that are leading upto he Wason interface.  

Have you tried it in Postman, I always try new connections there to ensure the creds are working correctly

Dave,

Error 400 is "Bad Request", according to http specs, not credentials issue.

First screenshot gives the response from Watson: {"error":"Unexpected token H in JSON..."}, so not valid JSON is to blame.

HTTP Request (screenshot 3) has to be modified to fix this: "context":"${context}" instead of "context":${context}

i believe its a bad request as it's not finding the oauth token that I'd expect the Watson interface to be looking for.

just to prove that a 400 series error could be related to creds I just changed the authentication on our of my POST calls so it would fail and this is what i got:
