Does this look familiar?
A customer taps your sneaker ad on Instagram. There's a discount coupon too — so they install the app.
They open the app — no sneakers, just the home screen. Search finds nothing, and the coupon is nowhere to be seen.
The customer leaves. The ad budget is already spent. And you can't even tell where they disappeared.
The problem isn't your ads — it's the 'broken bridge' between click and purchase.
ViaLink builds that bridge.
Deep links, explained in 10 seconds
Deep link: a link that takes customers to the exact screen inside your app
Just as a web link opens a web page, a ViaLink link opens a specific screen in your app. No app installed? It sends users to the store — and once the install finishes, it automatically opens the screen you meant to show.
One tap on the ad, straight to that screen
Customers land directly on the product or event screen from the ad. No more drop-off from wandering around your home screen.
No app installed? Still the right screen
Store → install → that screen opens automatically. Deferred deep linking remembers the destination even after install.
Referral codes applied automatically
The manual code-entry drop-off point disappears. The link alone identifies the referrer and triggers the reward.
Measure click → install → purchase
Connect the entire journey in a single pipeline. Prove campaign ROI with data — not estimates.
Connect QR codes to your app
QR codes on posters, packaging, and in-store displays become deep links. One scan opens the exact screen in your app.
Turn social media followers into app users
Links in Instagram and YouTube profiles and posts drive installs and conversions — with per-channel performance comparison.
A partner program for influencers and affiliates
Issue dedicated links to each partner and see per-partner installs and purchases as settlement-ready data.

"Shared product links that turn into revenue"
When someone taps a shared product link, even users without the app land on that exact product screen right after install — and payment attempts and successes flow into one pipeline.
- Users without the app land on the product screen right after install
- Build a click → install → purchase pipeline with the payment attempt API
- Compare purchase conversion rates across channels

"We just need simple deep links" — that's exactly why we built ViaLink.
Integration. Really, 3 minutes.
Copy one prompt instead of reading thousands of pages of docs.
Cursor, Claude Code, Copilot — any AI coding tool reads https://vialink.app/llms/{platform}.md and finishes the integration. ViaLink is the only deep link service that officially ships LLM-friendly docs (llms.txt spec).
4 things engineers want to verify
iOS Universal Links and Android App Links are supported out of the box. In-app browsers such as KakaoTalk, Instagram, and LINE are detected automatically and routed down the optimal path for each environment (including scheme fallback). ViaLink hosts apple-app-site-association and assetlinks.json for you.
Deferred deep linking: the device signature at click time is stored server-side, and on first launch after install, fingerprint matching restores the original destination screen. The matching window is 72 hours. It works without IDFA/GAID, so it remains valid under ATT.
Drop in payment attempt and success events with a single track() call, and click → install → payment attempt → payment success is attributed as one pipeline on a last-touch basis. Compare conversion funnels by channel, campaign, and link right on the dashboard.
Dynamic parameters in the form of /invite/:token are supported. No need to issue a new link every time — the server extracts and records the :token value automatically and passes it to the SDK callback. Ideal for referral and personalized links.
Last questions before you start
Do deep links stop working the moment my credits run out?
No, not immediately. Even after your credits are exhausted, we provide a generous grace period so your service keeps running smoothly. During that period we notify you that a top-up is needed, and deep link functionality continues to work for a set time. Once the grace period ends, features may be limited — so please keep an eye on your dashboard notifications.
How do I migrate from Firebase Dynamic Links?
We provide a migration guide that maps your existing FDL link structure onto ViaLink dynamic parameters.
Can I keep the links I used with another service?
Yes. With ViaLink's custom domain feature, you can keep your existing third-party link URLs unchanged. We also support a bulk link registration API and CSV import, so migrating even a large number of links is easy.
Is the privacy/fingerprinting approach compliant?
We use probabilistic matching that collects no IDFA/GAID, and our stance on GDPR and privacy law is published in the security whitepaper.
What happens after my free credits run out?
The same rule applies: 1 credit per completed app open. It's a prepaid top-up model, so there is no such thing as a surprise bill.
