What are dynamic links?

A dynamic link is a short URL like that you control. You print/share the QR for that short URL. Anytime later you can change where it points — without reprinting the QR. Bonus: every scan is logged so you can see how often each campaign/product is being scanned.

Create dynamic link

Name (your label)

Target URL (where the link points today)

Custom slug (optional)

All dynamic links

Name	Short URL	Currently points to	Scans	Last scan	Status

App Links

A single QR code that detects the scanner's device and routes them to the right place. iOS users go to the App Store, Android users to Google Play, everyone else (desktop, smart TV, etc.) goes to your fallback URL.

File QR

Upload a file (PDF, image, video, anything up to 25 MB) → get a short URL pointing at it → generate a QR. Scanning the QR downloads the file with its original filename.

Important: uploaded files are publicly accessible to anyone with the URL. Don't upload anything confidential.

Bulk generate from CSV

Upload a CSV with one row per QR code. Get back a zip of PNGs.

CSV format: data,name per row. name is optional; if omitted, files are auto-named qr-1.png, qr-2.png… Header row optional (recognized: data, url, text, content). Max 500 rows, max 1MB CSV.

Add user

Username

Password

Role

After creating, copy the password and share it with the user securely (Signal, 1Password share, etc.). They can change it later if you give them the new flow — for now, only admins can reset passwords.

Create API key

One key per consuming app. Name them so you know which key belongs to which app — e.g. myrepday-app, stacksy-com-au-marketing. The full key is shown only once at creation.

Key name (which app will use this?)

All API keys

Name	Prefix	Created by	Created	Last used	Status

Integration snippets

Replace $YOUR_API_KEY with a key created in the API Keys tab. Different apps should use different keys so any one can be revoked independently.

For Claude

Embedding directly in browser HTML exposes the API key in page source. Use only for trusted internal tools — for public sites, fetch on the server and serve the PNG from your own URL.
