Question about Trello. How do I use it w/ ROBLOX properly? [closed]

I'm trying to make a script where I can terminate script keys. I'm experienced with scripting, just new to HTTPService, that meaning I have absolutely no clue how to work Trello at all.

I'm trying to make it so I can take a random load of letters (EX: mbYVeEF9XWeJA4pfxK7UfwCcerjWhxVAgndh2dp8B285c) and put it into something like a Trello board and if the user misuses it, I can easily delete it and it'll mess the script up each time it does it.

I don't want the script done for me, all I want is an explanation on how trello works with ROBLOX and how I'd go about doing this.

Thanks, guys. :P
