That's because the event code not entered doesn't exist or is otherwise invalid.

There's a checksum built into the string of letters so attempts to iterate them can be rejected without loading the database.

 

Neat, I didn't know that. What's the checksum?

Essentially just ID + SHORTHASH(ID, SECRET). So it's not so much a checksum as it's a signature. Just a very small one.

Ah, so you're not validating Eventlink codes; you're just checking whether it's a code that someone has made an event for on decklist.lol. I see.

Correct!

Eventlink, unfortunately, offers no way it integrate with it at all.

I've noticed that creating a tournament on decklist.lol seems to result in the date not "sticking" as I would expect it to. For instance, I created a test tournament and set the Tournament Date to 04/04/2026 during that process. However, after clicking the Create Tournament button, I can see that the Tournament Date has been set to 4/3/2026 in the Tournament Information panel despite my earlier input. Is this intended behavior?
