Interfacing Oracle Assets and third party software for leases

I am looking to see if anyone else has created an interface from a third party software to Oracle Assets that handles lease creation, modification, and termination. We have existing legacy software that stores data from the leases but doesn't do anything with that data. The idea would be to extract the necessary data and use oracle assets but without manually having to enter data into the forms. Currently we handle around 1 thousand capital leases annually but need to prepare for soemthing in the ballpark of 25 thousand leases annually so a process that allows for a direct interface
