Help with gamejoin API

Help and Feedback Scripting Support

It would not work because that’s the api of https://n-rtd.up.railway.app and it’s public to use and since i want to rate limit games exceeding entirely and not one server only i need another check other than the game id because someone could make requests outside of roblox, fake the game id and get the experience rate limited

#22

Then you are out of luck, maybe provide api keys to each user.

Server ips don’t change while running or am i wrong? i got the idea from here Getting the IP of running game servers - #23 by grilme99

#24

Uhm sounds like a good idea! But i would still like to know why here the person accomplished it

#25

However, I’d assume a game could have multiple IPs as multiple servers would be running.

#26

Yes infact it would have iterated over the list of servers to check if the received was a valid server ip

#27

How would you know if it is valid since gameJoin only gives a single server ip at most.

#28

let me explain it well.

  1. the game submits a request to the API which will get the IP of the running server with req.connection.remoteAddress or req.headers['x-forwarded-for']
  2. it would get the list of all active servers containing their IPs
  3. compare the two IPs, if none matches then the request is not from roblox game servers
#29

How would you get this, however.

#30

i was hoping to use gamejoin.roblox.com because the response provides a list of running servers with the relative IPs

#31

That api only works for the roblox.com domain.

#32

Do you mean that only the roblox website can use it?

#33

Yes, only roblox.com itself can use it.

Actually from my researches sending the “referer” header with the value “www.roblox.com” will allow the usage of the api
