# installPageUrl

suspend fun installPageUrl(returnScheme: [String](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-string/index.html), sessionId: [String](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-string/index.html)): [String](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-string/index.html)

Wallet's hosted install page, carrying a fresh proof. Not the store listing — [openFrakApp](/developers/references/android/id-frak-sdk/applinkapi/openfrakapp/) handles that handoff itself.

#### Throws

| | |
|---|---|
| [FrakError](/developers/references/android/id-frak-sdk-core/frakerror/) | when the page cannot be minted: tracking is disabled, the device refused key material, or no merchant could be resolved. |
