Apple Pay Merchant

A simple Apple Pay merchant implementation, used for generating tokens for testing an Apple Pay payment processing gateway. It charges 1DKK, approximately 0.156$ on a provided Apple Pay card.

Note that no payment processing is performed, so no actual charges will be added to the card.

This setup requires you to set up a forward from your Apple Pay website, with a valid SSL certificate, to this container. By default port 8080 is used.

Setup

1. Set up Apple Pay with Apple

   Apple describes how you can prepare for Apple Pay integration here.

2. Add required certificates

   The Merchant Identity certificate (signed by Apple) and key must be added to the root of the directory as

   • merchant_identity.pem
   • merchant_identity.key

   The Payment Processing certificate (signed by Apple) and key must be added to the root of the directory as

   • payment_processing.pem
   • payment_processing.key

3. Create config.json

   The file config.json.example contains a list of required keys.

4. Boot the server with

   • Docker-compose

     Pull the :latest container docker image with

     docker pull clearhaus/applepaymerchant

     Use docker-compose to start the container. Tokens will be printed in the output log.

     docker-compose up

   • Manual workflow

     During development/testing, the server can be started inside a docker container.

     docker run -ti --rm -v "$PWD:/opt/applepaymerchant" -p 8080:8080 ruby:2.3 bash

     You need to install dependencies using bundle install. Start the server with

     bundle exec puma --config config/puma.rb

5. Forward Ports

   Forward traffic from your domain to the container on TCP port 8080. Note that your website must have a valid SSL Certificate.

6. Access Payment Site for testing

   Visit https://your.website on your iPhone or MacOS device, click the button that appears. If no Apple Pay button is displayed, your browser may not support Apple Pay.
