You don't need some complicated new "system"; you need some API that takes some structured data, validates it and processes it (in the system you already have). That's it.
After working on APIs from FMCSA, it's not easy, because they have no customer. My org was required by law to meet their deadlines. They setup a test api 2 months after the deadline. Their backup method of sending the data was another 2 weeks after that. It was through soap because they said that was the most secure. We had a team contact them about ambiguity in their documentation and it took 6 months to get a reply.
