Accompanying blog post: "How to take payments on the web with the Payment Request API"
A simple front-end demonstration of the Payment Request API. You can just enter made-up details - it just simulates the server-side so won't actually take a real payment!
To run locally, spin up any static web server, such as python -m SimpleHTTPServer
or Chrome's web server extension.
Then load it up in a browser with support for the Payment Request API - try Samsung Internet v5, Chrome for Android, or preview builds of Edge.
If you're not familiar with pointing your mobile phone to a local server on your development machine, there are some instructions here and Samsung Internet specific info here, under 'How do I debug'.
Let us know if you have any questions @samsunginternet!
