GMS 2 How to receive information from the server when game launches



Hello dear community ! I have stacked with the problem that really bothers me and maybe someone can help with that. So I have a website with user log-in form and once the user will click on the login button I want to open the game and send information like : user email, user ID, user name etc. to that game so when the tab with the game finally loaded it will show all that info on the starting screen. The problem is, methods that I have found to establish the connection between server and the game are based on the game calling server first (like http_get or http_post_string) and I need to send data to the game at a launch time. Any ideas how is that possible ?

I would be very thankful to any ideas because I ran out of them. Thanks !
