PSystem

A prototype of a payment system

Description

That's a quite simple prototype of a payment system with 4 different types of transactions.

• Authorize — hold the money on the customer's account (we mock calls to customer's bank, take a look at ProcessAuthorizeTransactionService)
• Capture — move authorized money from the customer's account to the merchant's account
• Refund — move captured money back from the merchant's account to the customer's account
• Void — invalidate an auhtorize transaction

For now we have web interface at: /admin (use seeds or create an instance of Admin)

Demo

The demo instance is deployed on heroku: psystem-dev.herokuapp.com

Quick setup

We have a script for quick local deployment.

The quick setup script requires installed docker and docker-compose.

make install

And then you're able to run the app:

make up

API docs

There's a Postman collection here

Don't forget to use the value from the Access-Token header after authentication request. Put it to the Authorize header for further requests.

Tests

Use the next command to run usual rspec tests

make rspec

Use the next command to run feature tests

make rspec_features

Use the service runner to run some development stuff like

docker-compose run runner bundle install
