But can you tell me, how to rank the players from the game, I tried to run the api by myself manually, and it works, but the thing is I want to make an automated application, so I have to make this do it itself
You won’t be able to make calls directly from Roblox to Roblox. This is a security measure and there isn’t anyway to do so for good reason!
It might be better to set up a server of some sort which handles ranking (outside of Roblox). Then, make a request to that server which will handle the ranking for you.
Yeah, there are a few on Youtube videos that work out good but they are somewhat out of date. Try searching up “group ranking bot roblox” or something along those lines, there should be something relevant that pops up.
Once you get further into one of the tutorials I’m sure they’ll mention something about cookies. I do want to warn you though, Roblox has been invalidating bot cookies (region locking them, to my knowledge) meaning wherever you’re running your server must be running in the same generalized region or country where you got your bot cookie from. If you have any questions about it once you understand the concept or at all, let me know. I’ll try my best to help.
