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.

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 so the button matches ours. Either hotlink our logo or inline it as a data URI — both work, neither needs you to host a file.

Logos & brand assets

Hotlink these straight from us — they're served with Access-Control-Allow-Origin: * and a long cache, so they're safe to use in CSS, <img> and canvas from any domain. Every URL below is permanent: we add new files rather than repaint one in place. Copy them if you'd rather self-host; just don't recolour or restretch the mark.

App icon

The rounded tile, opaque. Carries its own background, so it sits on anything — use it where a favicon or an avatar goes.

Colour	Where it's used
`#35c77c`	Untap green — the import button's fill.
`#10241a`	Label on the green button.
`#313649`	The dark mark. Safe as a text colour next to it.
`#1b1e24`	Our app background, if you want the button on a dark panel.

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.
