Deep Linking Validator

Automatically analyze your site to verify that your apple-app-site-association and assetlinks.json files are properly configured for deep linking.

Median's Deep Linking Validation utility helps verify that your domain is properly configured for deep linking. This utility checks your domain's compliance with the requirements for hosting an Apple App Site Association (AASA) file and a Digital Asset Links assetlinks.json file. These files verify your ownership and control of your domain, and your intent to create a "app-to-website association" and link your website to your mobile app. You must host these files on your domain to support deep linking to your app: iOS Universal Links and Android App Links.

Scan your domain using our tool to verify your AASA and assetlinks.json files are:

  • Accessible over HTTPS without redirects.
  • Properly served with the correct headers and status codes.
  • Valid JSON formatted to meet Apple and Android requirements.

If your files validate successfully but deep linking isn’t functioning as expected for your app, we recommend posting in our Discussion Forum.
