Reverse Engineering in API

I don't feel like I'm an expert a lot of the time, and I write code all day. So what API were you trying to? So I was just getting on TikTok at the time. There's a lot of obscurity around their web APIs. And so what is that? I did not dig deep in a TikTok. Don't ban me TikTok. But I hacked the Yosemitecamping.gov website because I wanted to go camping. It's Ticketmaster. These are all reasons why you want to potentially understand how the website works in those teams.
