When you send a message, ROBLOX sends out (3?) different requests to their domains and these domains areĪnd once again, it checks for messages at GET /v1.0/get-messages?conversationId=IDGOESHERE&pageSize=PAGESIZE HTTP/1.1.

I currently don't know what pageSize is, or how conversationIds are found. Please note that conversationId doesn't take userIds as parameters. GET /v1.0/get-messages?conversationId=IDGOESHERE&pageSize=PAGESIZE (DEFAULT 30?) HTTP/1.1

ROBLOX makes a request for the actual message(s) as well If you have someone send you a message, you can see the number changes. is the URL the system uses to check for how many messages are available. ROBLOX's chat system checks for (unread) messages every time you open the chatbox. When you send a message through ROBLOX's chat system, it goes through How ROBLOX's chat checks for messages On the sending end of your chats What happens when you send a message If you find any errors, please message me on ROBLOX (Stormersoul). Please note this information may not be 100% accurate!
