The API is intended to be called by multiple clients to perform the same calculation. I don't want to store client data i.e. ODBC info on the server that the API is on. The ODBC name is one of the parameters used in the API function call. The function needs the ODBC name to access the client data. Hypothetically if the functions gets client data to calculate revenue, the data is on the client side, the function API call is on the server, would the client data be visible to anyone else but the client in performing the calculation.
