如何访问 Apple 的 AASA 验证器（应用搜索 API 验证工具）？

Question

When building an Apple App Site Association file (AASA or apple-app-site-association file), it's very easy to get it wrong. That's why Apple built a " App Search API Validation Tool " ( ref1 , ref2 ).

This seemed to be available as recently as June 2022 at https://search.developer.apple.com/appsearch-validation-tool/ . However, that site now redirects to a generic page about universal links .

I would like to use Apple's tool to validate my AASA file because when I chose my build in App Store Connect, it shows that there are problems with my AASA file:

DOMAIN STATUS: 1 invalid domain

CACHE STATUS: Cannot Reach AASA File

DEBUG STATUS: Invalid Entitlement: Unknown ID

How do I access Apple's App Search API Validation Tool?

I know there are 3rd party AASA validators:

• https://branch.io/resources/aasa-validator/
• https://yurl.chayev.com/

... however, these are not built by Apple, so may not be as thorough as Apple's tool. Case in point, my AASA file succeeds on both of these sites, even though it fails on App Store Connect.

Answer 1

I can't recall since when or why, but I have been using the following successfully:

https://app-site-association.cdn-apple.com/a/v1/<domain>

eg

https://app-site-association.cdn-apple.com/a/v1/spotify.com

Answer 2

Thank U for your 3rd party AASA validators, those work for me.

Maybe you can try it with your iPhone, in Setting -> Developer -> UNIVERSAL LINKS/Diagnostics.
