Learn

What you need to know.

Without a connected domain of your own, there are no short links in LINK.
Enter it under LINK → Domain without www., set the DNS records at your provider, use Erneut prüfen (check again) until Live. Whole domain: A for @ and CNAME for www. Subdomain: CNAME, sometimes also TXT.
DNS fehlt (DNS missing) means the records are missing or haven't arrived yet. Bestätigung nötig (confirmation needed) means the TXT record is missing.
Disconnecting doesn't work while short links still run on it or the SITE sits under it.
Owners, Creators, Admins and Technicians may change domains.

The target URL starts with https:// or http://. Endings: lowercase letters, digits and . _ ~ -, slashes work, e.g. deals/voltaro.
Only api as the first part is reserved: api/docs doesn't work, apidocs does.
Each ending exists once per domain. Deleted links keep their ending for another 30 days.
Live ab (live from): before that, the visitor lands at the Ersatz-Ziel (fallback target). The filter Geplant (scheduled) shows such links.
You create groups via + Gruppe or while creating a link. With Standard-Gruppe (default group), new links land in it automatically.

A new target URL applies to all short links and QR codes already shared, after about 30 seconds at most.
Under Aktivität (activity) every change is listed with name and time, Rückgängig (undo) brings back the old state.
Archivieren (archive) stops the redirect, the link stays in the list. Löschen (delete) removes it, for 30 days you get it back under Zuletzt gelöscht (recently deleted).
The Ersatz-Ziel under LINK → Einstellungen catches unknown, archived, deleted and not yet live links, for all domains.

The quick QR code from the row menu is not saved. You create saved codes under LINK → QR CODES.
Download only as PNG in 512, 1024 or 1600 px. There is no SVG.
The Code Builder turns a shop address and discount code into a link that redeems the code, and shares it as a short link, QR code, on the SITE or as a chat command. Not every shop can fill in the code in advance.

No cookies. Origin, devices and sources only from 5 different visitors. Clicks are deleted after 90 days.
Link-Vorschauen (link previews) from Discord or WhatsApp don't count as a click.
?utm_campaign=… appears under Kampagnen (campaigns) and is not passed on to the target.
Importing from CSV, Bitly, Rebrandly or Dub overwrites nothing: existing endings and duplicates are skipped and reported.

Complete the tasks in your workspace and reload this page. The course sees by itself what is done.

Your own domain live
Connect your own domain or subdomain under LINK → Domain and get it to Live with Erneut prüfen.
A drop link with Live ab
Create a link with Live ab in the future, e.g. drops/herbst, and find it under the filter Geplant.
Order with groups
Create at least two groups and sort links into them.
Set the Ersatz-Ziel
Enter an Ersatz-Ziel under LINK → Einstellungen. Then open your scheduled ending from the previous task and see where you land.
Saved QR code
Under LINK → QR CODES, create a QR code for one of your short links, design it, scan it with your phone and save it.
