Simple Payment Integration Gateway. Proof of Concept. No Warranty
This simple Sinatra service does one thing -- accept a payment request and verify it against Authorize.net.
Any Ruby 2.x should suffice. You will also need ngrok to set up a tunnel if you're running this locally. Because Authorize.net is stupid, you must run this in such a way that you can call it via https, even if you're just running it locally. For testing purposes, use ngrok.io to set up a tunnel and hit the page that way.
To prepare:
bundle install
You must create a .env file based on .env-example with your Authorize.net keys. If running to test it, use your sandbox keys!
To run:
ngrok http 4567 # in a window by itself. Note the https URL it generates!
ruby pig_in_a_box.rb
Right now this responds to exactly two endpoints:
From a browser: GET '/' will give you a test form that will use Accept.js to validate the credit card and get you an ANet token. It will then post to the other endpoint to test it and return the results.
AJAX/XHR POST /api/v1/payments will send the requested payment to ANet and return a simplified result JSON:
Expects:
{
"opaqueData": {
"dataDescriptor": "...",
"dataValue": "..."
},
"amount": 42.42,
"customerEmail": "[email protected]",
"orderDescription": "99 bottles of beer on the wall"
}A successful charge returns:
{
"authCode": "...",
"responseCode": "...",
"messages": [ { "code": "...", "description": "..."}, ...]
}Any error returns:
{
"errors": [ { "code": "...", "description": "..."}, ...]
}
