Cant find a lot of info about these functions, i want to know if i can send global data out from studio, to real servers
Technically.
While you can’t generally use MessagingService while in Studio, you should be able to use the open cloud API in order to achieve the same outcome. Note that it only works for local tests, and you should use RunService:IsStudio() to ensure you don’t try running it in an actual server (else it will break)
How do i use cloud api to do this?
Make use of HTTPService to send a post request to the relevent URL, with the data containing the message you want to send
