# assetlinks.json validator

Paste an assetlinks.json file to check statement shape, relations, package name and SHA-256 fingerprints, optionally against an expected package and certificate fingerprint.
assetlinks.json contents

Paste a file to check it.

Everything runs in this tab; the paste never leaves it. This checks the shape of the statement list: the relation string, the android_app namespace, the package name, and the SHA-256 fingerprints. It does not know your domain, cannot read what your server actually serves at /.well-known/, and cannot prove the fingerprint belongs to your signing key. Pull the fingerprint from Play App Signing or keytool -list -v -keystore and use the compare fields to be sure.
