Snapchat's click identifier, appended to ad clicks so the destination site's Snap Pixel can report your actions back to Snap, matched to the click and your account.
Snap appends the click ID (you will see it capitalized as ScCid in the wild) to swipe-ups and ad clicks leaving Snapchat. The destination's Snap Pixel captures it and attaches it to the events it reports back, directly or through Snap's Conversions API.
Snap's documentation recommends passing it with server-side events to improve match rates, meaning the tie between your purchase and your Snapchat identity.

Remove sccid automatically
Rather's Link Shortener strips sccid and hundreds of parameters like it, right in the

How do I remove sccid automatically?
The free, open-source browser extension Rather's Link Shortener removes sccid automatically in the address bar, in copied links, and in shared links, on Chrome and Firefox. You can also simply delete the parameter by hand: everything from sccid= up to the next & or the end of the URL.
