If you are pulling data from two different environments you would want to store them in two different locations.
For example if you are pulling data via API and inserting into SQL tables you would want two databases:
Database A: Development server data
Database B: Production server data
That way any time you are querying the data you know which set is which.
As for knowing which calls go to which account there is a corpToken that will link to a specific database. Unique to each instance of Bullhorn.
For example when logging in you are returned the following:
"BhRestToken" : "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"restUrl" : "https://rest.bullhorn.com/rest-services/corpToken/"
That corpToken will be unique to each server. One for Development server. One for Production server.
This will help you keep track of which calls are going to which server.
