PaypalClient

Ruby client for the PayPal REST API. PayPal offers their own SDK but that felt a big heavy and was not seeing active development at the end of 2018.

PaypalClient is using Faraday to make the http calls to the Paypal API and uses ActiveSupport::Cache::MemoryStore to store the auth token required to make authenticated requests to Paypal more info.

Add this line to your application's Gemfile:

gem 'paypal_client'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paypal_client

To list payments

paypal_client = PaypalClient::Client.build
response = paypal_client.get('/payments/payments').body
response[:payments].each do |payment|
  puts "Paypal payment with ID: #{payment[:id]}"
end

PaypalClient::Client.build requires the following environment variables to be set:

PAYPAL_CLIENT_ID=<paypal_client_id>
PAYPAL_CLIENT_SECRET=<paypal_client_secret>
PAYPAL_SANDBOX=true

You can also configure the client using PaypalClient::Client.new as in the following example.

paypal_client = PaypalClient::Client.new(
  client_id: <paypal_client_id>,
  client_secret: <paypal_client_secret>,
  sandbox: true,
  cache: Rails.cache,
  version: 'v1'
)

TODO

There is a good amount of unit testing in spec/paypal_client_spec.rb. To run those test no active Paypal Developer account is required. To run the tests in spec/integration/integration_spec.rb valid Paypal sandbox credentials are required.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
