Braintree Ruby library

The Braintree gem provides integration access to the Braintree Gateway.

Please Note

The Payment Card Industry (PCI) Council has mandated 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 for more information.

Installation

gem install braintree

Or add to your Gemfile:

gem 'braintree'

Optionally, you may also include LibXML for more performant XML parsing. If LibXML is not present, REXML will be used instead.

gem 'libxml-ruby'

Dependencies

• builder

The Braintree Ruby SDK is tested against Ruby versions 2.6, 2.7 and 3.0.

The Ruby core development community has released End-of-Life branches for Ruby versions lower than 2.6, which are no longer receiving security updates. As a result, Braintree no longer supports these versions of Ruby. We have updated our gem specifications to reflect these updates.

Versions

Braintree employs a deprecation policy for our SDKs. For more information on the statuses of an SDK check our developer docs. Minimum supported versions are also available in our developer docs.

Major version number	Status	Released	Deprecated	Unsupported
4.x.x	Active	May 2021	TBA	TBA
3.x.x	Deprecated	October 2020	May 2023	May 2024
2.x.x	Deprecated	April 2010	October 2022	October 2023

Quick Start Example

require "rubygems"
require "braintree"

gateway = Braintree::Gateway.new(
  :environment => :sandbox,
  :merchant_id => "your_merchant_id",
  :public_key => "your_public_key",
  :private_key => "your_private_key",
)

result = gateway.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.

Bang Methods

Most methods have a bang and a non-bang version (e.g. gateway.customer.create and gateway.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 = gateway.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 = gateway.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.

Developing (Docker)

The Makefile and Dockerfile will build an image containing the dependencies and drop you to a terminal where you can run tests.

make

Linting

The Rakefile includes commands to run Rubocop. To run the linter commands use rake: rake lint.

Tests

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.

Suppress Braintree Logs

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
gateway.config.logger = logger
