The Braintree gem provides integration access to the Braintree Gateway.

The Payment Card Industry (PCI) Council has {mandated}[http://blog.pcisecuritystandards.org/migrating-from-ssl-and-early-tls] that early versions of TLS be retired from service. All organizations that handle credit card information are required to comply with this standard. As part of this obligation, Braintree is updating its services to require TLS 1.2 for all HTTPS connections. Braintree will also require HTTP/1.1 for all connections. Please see our {technical documentation}[https://github.com/paypal/tls-update] for more information.

gem install braintree

Or add to your Gemfile:

gem 'braintree'

require "rubygems"
require "braintree"

Braintree::Configuration.environment = :sandbox
Braintree::Configuration.merchant_id = "your_merchant_id"
Braintree::Configuration.public_key = "your_public_key"
Braintree::Configuration.private_key = "your_private_key"

result = Braintree::Transaction.sale(
  :amount => "1000.00",
  :payment_method_nonce => nonce_from_the_client,
  :options => {
    :submit_for_settlement => true
  }
)

if result.success?
  puts "success!: #{result.transaction.id}"
elsif result.transaction
  puts "Error processing transaction:"
  puts "  code: #{result.transaction.processor_response_code}"
  puts "  text: #{result.transaction.processor_response_text}"
else
  p result.errors
end

You retrieve your merchant_id, public_key, and private_key when signing up for Braintree. Signing up for a sandbox account is easy, free, and instant.

Most methods have a bang and a non-bang version (e.g. Braintree::Customer.create and Braintree::Customer.create!). The non-bang version will either return a SuccessfulResult or an ErrorResult. The bang version will either return the created or updated resource, or it will raise a ValidationsFailed exception.

Example of using non-bang method:

result = Braintree::Customer.create(:first_name => "Josh")
if result.success?
  puts "Created customer #{result.customer.id}"
else
  puts "Validations failed"
  result.errors.for(:customer).each do |error|
    puts error.message
  end
end

Example of using bang method:

begin
  customer = Braintree::Customer.create!(:first_name => "Josh")
  puts "Created customer #{customer.id}"
rescue Braintree::ValidationsFailed
  puts "Validations failed"
end

We recommend using the bang methods when you assume that the data is valid and do not expect validations to fail. Otherwise, we recommend using the non-bang methods.

• Documentation

The unit specs can be run by anyone on any system, but the integration specs are meant to be run against a local development server of our gateway code. These integration specs are not meant for public consumption and will likely fail if run on your system. To run unit tests use rake: rake test:unit.

To suppress logs from Braintree on environments where they are considered noise (e.g. test) use the following configuration:

logger = Logger.new("/dev/null")
logger.level = Logger::INFO
Braintree::Configuration.logger = logger
