All of the documentation I am seeing is describing the creation of a web app and distribution of it from the clover app market.
My customers want me to be able to retrieve their data using our existing service.
I am trying to figure out how I go about getting any credentials or authentication information I would need to be able to get a merchant's data (with their permission) via REST in a native C++ Windows Service that we would be responsible for deploying on a customer's machine. Can someone describe this to me or let me know if it isn't possible?
