Automatically change YouTube thumbnail & title based on our database API

I want a web app /script/ desktop app... really anything that can do two things: 1) Randomly change the youtube thumbnail (right now, it defaults to our uploaded image, so every live stream that we do it has the exact same thumbnail) 2) Change the YouTube video's title. After we live stream, the title remains the same for all events... we have a database and API for all of our events (specific to each client). After the event, we want the video title to change automatically - the API has the "service title". We have dozens of clients that we need to implement this with. The UI / GUI can be very minimial... it's just for internal use, so as long as it works, we don't care what it looks like!
