Watson dialog cURL conversation post request not passing form data

Question

When making a post cURL request as below to try and continue a created conversation watson instead returns a new conversation.

curl -u \"USERNAME\":\"PASSWOR         


        

Answer 1

The service expects an application/x-www-form-urlencoded POST request

To do that in curl you need to use the -d parameter:

curl -u "USERNAME":"PASSWORD" -X POST 
  -d conversation_id=CONVOID 
  -d client_id=CLIENTID
  -d input="What type of toppings do you have?"
  "https://gateway.watsonplatform.net/dialog/api/v1/dialogs/DIALOGID/conversation"

-d, --data

(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded. Compare to -F, --form.
