So I am a noob to this because I normally despise Trello in Roblox for things like storing applications, but I want to know how would I create a Trello board and then be able to get info of it.
I want to try to make a system where if a certain users name is on the board then when the player joins it will get their name from the board that they might be in and then set the leaderboard rank string to whatever is inside of their tab
LisaF854 made a really useful API that should suit all of your needs. I believe there are functions to get and set the title and description of cards. There are also a lot of other functions in this API that are quite useful for making systems like that.
Or, if you’re interested in learning how to do these types of things directly with HttpService and without any sort of module, I would recommend reading through the Trello API documentation.
