FAQ
- What does the assetlinks.json checker validate?
- It fetches your domain’s assetlinks.json file, verifies HTTP reachability, valid JSON structure, and optionally matches your Android package name and SHA256 certificate fingerprint.
- Does this also check iOS Universal Links?
- Yes. The tool validates apple-app-site-association (AASA) at /.well-known/ and the root fallback path, and checks whether your Team ID and Bundle ID appear in the file.
- How many free checks can I run?
- Five validations per day per browser. Create a free HighGrow account for unlimited domain validation in Developer Hub.
