The documented API only allows interaction with the Watson Conversation service once it is configured. Is there any API which will allow the configuration. For example create intents, entities etc...
Good questions and we agree. We have plans shortly to expose a lower level set of APIs that will address your concerns. Brian
At this point in time the APIs for what you want to do are not publicly exposed.
Just to close out this question. The API for Watson Assistant (formerly Watson Conversation) can be seen here. The Watson Developer SDKs support that API.
To see the API in action there are several examples. I wrote a tool demonstrating some of the API calls and a so-called EgoBot that mutates during the dialog, i.e., adds objects by using that API.
