App clips - Launch appclip safari in html page inside safari on a button click. I have the testflight app

Subject: Help Needed with App Clip Implementation

Hi Team,

I need some assistance with implementing App Clip behavior in safari and also experimenting using TestFlight app.

Default App Clip URL: https://appclip.apple.com/id?p=com.jey.ppclient-prod.appclip

Website for App Clip Integration: https://appclip-sand.vercel.app/customer

1. Current Behavior:

Default App Clip URL:

When I embed the default App Clip URL in an HTML <a> tag like below:

<a href="https://appclip.apple.com/id?p=com.jey.ppclient-prod.appclip">Launch App Clip</a> it does launch the App Clip. but it says the appclip not supported in your region

I've already added this configuration under Local Experience in App Store Connect.

1. Website Integration:

I’ve registered the site using the Advanced App Clip Experience.

The apple-app-site-association file is in place.

When I visit the site, the App Clip does launch as expected.

1. What I Need Help With:

I want to launch the App Clip from a custom button click, using either:

The default App Clip URL, or

The website URL (e.g., https://appclip-sand.vercel.app/customer) with additional query parameters like userId or sessionId.

Is there a supported way to achieve this—perhaps through JavaScript or a specific <a> tag setup that works with either Local or Advanced Experience?

Your guidance would be greatly appreciated.

Thanks, Jey
