I've been trying to use node red to work with watson personality insight. So far so good, I've created an account in IBM Watson Cloud and I generated a new lite project on personality insight.
My problem is in node red, when I put my API key on it it says it's unauthorized. I'm not too sure if I have to put my username and password too, I've tried all of them but nothing seems to work.
Binding the service will allow the node to discover the credentials. What you are most likely missing is the endpoint, which you have as the default. I am guessing your service instance is not on the default of US South.
