What is an Apple App Site Association (AASA) file?
The Apple App Site Association (AASA) file is a JSON document that lives at the root of your secure website. It is used by iOS to verify that the website is allowed to open specific links in an associated app, rather than in Safari.
How do I use this site to verify my AASA file?
To verify your AASA file, simply enter your website (e.g. youtube.com) above. Our tool will fetch the file from Apple's servers and perform a series of checks to ensure everything is correct - including proper JSON format and the presence of necessary keys.
Is there a cost to use this site?
Our basic verification service is free to use. We will also offer premium services, such as AASA file monitoring for breaking changes and more customization options for the dashboard at a fee.
