Unfortunately, I’m not familiar with APIs. I know they exist, I know they connect 2 or more things, but that’s pretty much it.
To be honest, for a musician, I already know more than I expected to ever know when it comes to this kind of “tech-talk” 
I’m glad I learned it, though, because it allows me to do a lot of things myself that would require lots of different people and of course, lots of investment.
