I don’t remember off the top of my head how that data is formatted. It might be a list of tpids, an id I unique to the FIRST website, but I’m unsure. Maybe check through the old test data stored on the TBA Github.
In the meantime, might I recommend Cheesy Arena, an open source alternative field management system. It depends on the TBA API, so you aren’t restricted by FIRST’s pages going down. Plus, it can auto post results to TBA
