How to forward URL parameters?

After creating your link, open it from your dashboard and click the URL tab. Tick the Forward URL Parameters checkbox and click Update.

From that point on, any parameters attached to your short link will be carried over to your destination URL.

Imagine your short link is nimble.li/a1b2c3 and your destination URL is example.com/promo. With URL Parameter Forwarding enabled, when someone clicks nimble.li/a1b2c3?campaign=christmas they'll land on example.com/promo?campaign=christmas.
