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.

gem install braintree

Or add to your Gemfile:

gem 'braintree'

Quick Start Example

require "rubygems"
require "braintree"

gateway =
  :environment => :sandbox,
  :merchant_id => "your_merchant_id",
  :public_key => "your_public_key",
  :private_key => "your_private_key",

result =
  :amount => "1000.00",
  :payment_method_nonce => nonce_from_the_client,
  :options => {
    :submit_for_settlement => true

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

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 #{}"
  puts "Validations failed"
  result.errors.for(:customer).each do |error|
    puts error.message

Example of using bang method:

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

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.

More Information

Developing (Docker)

The Makefile and Dockerfile will build an image containing the dependencies and drop you to a terminal where you can run 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 ="/dev/null")
logger.level = Logger::INFO
gateway.config.logger = logger
