Fintech apps and install links

Every compliance requirement adds a hop, and every hop is somewhere the tap can die.

The extra steps

Regulated products often route through disclosures, region gates and consent screens before reaching the store. Each is a redirect, and each one can drop query parameters or lose the visitor entirely.

By the time the store URL is reached, a campaign token attached at the start may be long gone. Attach them at the final hop instead.

Region gating

Serving different destinations by country is normal here, and it interacts badly with in-app browsers: the gate renders fine, the store link at the end does not. The failure looks like people abandoning at the disclosure when they actually abandoned after accepting it.

Verification flows

Identity checks that open camera access or third-party SDKs generally fail inside a WebView, as described in the payments write-up. If onboarding starts on the web, it should move to a real browser before any of that begins.

Trust and the address

In finance, the address people see matters more than in other categories. A generic shortener in an ad for a banking product is a legitimacy problem as much as a technical one, so routing through a domain that visibly belongs to you is worth the setup.

The audit worth doing

• Count the redirects between ad and store, and remove any you can
• Confirm campaign parameters survive to the final URL
• Test the whole chain from inside Instagram on a real iPhone
• Check that region gates behave when the browser cannot store consent
