Creating and Accessing new Subscriptions, created via API   

Hello,

We have a question regarding the way we could automatically create and access subscriptions.
What we’d like to accomplish is to be able to create new subscriptions and access them all via API and completely automatically within our main Organization subscription.

Here are the obstacles we face:
1. At the moment we create new Subscriptions manually via Rose Central, but we couldn’t find any API documentation for it, only for main rose.
2. In order to access data from subscription via Application, we have to first make manual mapping in the application, so we’d be able to access this specific subscription via API.
We couldn’t find any API to work with Application either.

Could you please advise.
Thanks!
