How do I remove a card/edit a value in trello?

I'm currently using the TrelloAPI (https://www.roblox.com/library/214265621/Trello-API), and have made a board, which has a list, and then the list contains cards with player names on them (e.g. Player1, Player2, Player3, etc). Each of these cards has a value in the description (e.g. 100, 200, 300, etc).

Here's my code at the moment (everything works fine and I have no problem scripting, I'm just wondering if anyone knows how to do the question above/below)

API = require(game.ServerScriptService.TrelloAPI)
Board = API:GetBoardID("Money")
Player = script.Parent.Parent
PlayerName = Player.Name
Card = API:GetCardID(PlayerName,Board)
FinalCard = API:GetCardInfo(Card,Board)
Money = tonumber(FinalCard.desc)

As I said, this works perfectly okay at the moment.

The only problem I'm having is, I want to update the description of the card (this would happen on an event occurring) , and if that's not possible, then remove the card and replace it with a new one if possible, with a new value.

If NONE of that is possible (which hopefully isn't the case), then I've heard about people using "servers" to store their information. I assume this is like a simple HTML website type thing, and if it's free, then I was wondering how I'd go about doing this? Would that allow me to make some sort of table type thing and then edit that? Thanks for the help.
