Apple Pay integration example

A minimal two-page reference for integrating Apple Pay with the PayConex payment gateway: register merchant domains with the v4 API, then process an Apple Pay SALE through QSAPI.

1. Merchant registration

HMAC-sign and submit a domain registration request so Apple Pay can run on the HTTPS host you are serving this app from.

2. Checkout / SALE

Render the Apple Pay button, validate the merchant session, and charge the tokenized payment via QSAPI (tender_type=APay).

Before you start

Copy config.example.php to config.php and add PayConex cert credentials.
Serve this app over HTTPS on a registered domain (see README for local applepay.local or your deploy host).
Place the PayConex Apple Pay domain-association file at /.well-known/apple-developer-merchantid-domain-association.
Apple Pay works in Safari and (with iOS 18+) third-party browsers when using the official JS SDK button.
