# Invalid Digital assets links

## Description

Le protocole Digital Asset Links et l’API permettent à une application ou à un site Web de publier des déclarations vérifiables sur d’autres applications ou sites Web. Par exemple, un site Web peut déclarer qu’il est associé à une application Android spécifique, ou il peut déclarer qu’il souhaite partager les informations d’identification de l’utilisateur avec un autre site Web.

Si un deeplink pointe vers <https://target.xyz> par exemple, alors ce dernier doit avoir un endpoint `/.well-known/assetlinks.json`

Essayer aussi: <https://digitalassetlinks.googleapis.com/v1/statements:list?source.web.site=target.com>

Ce lien **ne doit pas** être joignable via le protocol **HTTP** non sécurisé.

Il doit êgalement contenir le package de l'application, si cela n'est pas le cas, des applications illégitimes pourraient tenter de s'associer au site.

Dans le cas où les deeplinks utilisent **plusieurs sous-domaines**, chacun de ces sous-domaine doit posséder un endpoint `/.well-known/assetlinks.json`

Inversement, si un wildcard est utilisé, l'endpoint doit être à la racine du domaine wildcard (https\://\*.target.xyz => <https://target.xyz/.well\\_known/assetlinks.json>).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://blog.s1rn3tz.ovh/pentest-mobile/android/deeplinks-vulns/invalid-digital-assets-links.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
