Import decks into Untap.in

A one-link integration for deck builders and card sites.

Let your users push a deck straight into Untap.in with a single link. They click it, Untap opens a confirmation dialog with a live preview of the matched cards, and they save it to their collection. No API keys, no login handoff, nothing to host.

How it works — point users at https://untap.in/import-deck/<your-deck-url>. Untap fetches that deck from your site, resolves the cards, detects the game automatically, and opens the import dialog. If the user isn't logged in yet, they log in first and the import resumes.

Try it live

Paste one of your public deck URLs to generate a working link and copy-paste snippets.

Copy-paste examples

When the button sits on the deck's own page you don't need to hardcode anything — just read window.location.href.

Branded button styles (optional)

Drop-in CSS + logo so the button matches ours. The logo is inlined as a data URI so you don't host anything.

Link format

https://untap.in/import-deck/<deck-url>

Part	Notes
`<deck-url>`	Your deck's public URL. Recommended: `encodeURIComponent()` it so query strings and special characters survive. A plain URL works too (Untap adds `https://` if you omit the scheme).
Game / CCG	Detected automatically from the deck source — you don't pass it. Untap resolves the game and the deck name from the fetched deck.
Login	Handled first-party by Untap. If the user is logged out, they log in and the import continues — you never touch their credentials.

Supported already? Untap imports from dozens of builders (Moxfield, Archidekt, TappedOut, Limitless, deckplanet, TCGplayer, and many more). If your site isn't supported yet, email hello@untap.in with a couple of sample deck URLs and we'll add a handler.

Ways to surface it

A few patterns we like — mix and match to fit your UI.

Deck-page button
A "Play Deck on Untap.in" button next to your Copy / Export actions on every public deck page. The most direct path.
Open in a new tab or a popup
New tab is simplest and mobile-friendly; a small window.open popup keeps users in your flow.
Copy-link / share menu
A "Copy Untap import link" item so users can paste it into Discord, a forum, or a friend's DM — the deck imports for whoever opens it.
QR code
Render the import link as a QR on a deck page so a user can jump from desktop to the Untap app on their phone.
Bulk / cube exports
The same link works for large lists and cubes — wire it into your "export cube" action.
Server-side redirect
Expose /export/untap/<id> on your side that 302-redirects to the Untap import link — handy for email/CMS where you can't run JS.

Legacy embed widget deprecated

Heads up — the older embeddable iframe widget (/user/deck-importer?uri=…) reads the user's Untap login out of cross-site storage to save silently. Browser storage-partitioning (Safari ITP, Chrome CHIPS) increasingly blocks that, so it works inconsistently. It still runs for existing embeds, but new integrations should use the /import-deck/ link above — it's first-party, needs no storage access, and won't break as browsers tighten up.
