The Stripe Ruby library provides convenient access to the Stripe API from applications written in the Ruby language. It includes a pre-defined set of classes for API resources that initialize themselves dynamically from API responses which makes it compatible with a wide range of versions of the Stripe API.

The library also provides other features. For example:

• Easy configuration path for fast setup and use.
• Helpers for pagination.
• Tracking of "fresh" values in API resources so that partial updates can be executed.
• Built-in mechanisms for the serialization of parameters according to the expectations of Stripe's API.

See the Ruby API docs.

You don't need this source code unless you want to modify the gem. If you just want to use the package, just run:

gem install stripe

If you want to build the gem from source:

gem build stripe.gemspec

• Ruby 2.3+.

If you are installing via bundler, you should be sure to use the https rubygems source in your Gemfile, as any gems fetched over http could potentially be compromised in transit and alter the code of gems fetched securely over https:

source 'https://rubygems.org'

gem 'rails'
gem 'stripe'

The library needs to be configured with your account's secret key which is available in your Stripe Dashboard. Set Stripe.api_key to its value:

require "stripe"
Stripe.api_key = "sk_test_..."

# list charges
Stripe::Charge.list()

# retrieve single charge
Stripe::Charge.retrieve(
  "ch_18atAXCdGbJFKhCuBAa4532Z",
)

For apps that need to use multiple keys during the lifetime of a process, like one that uses Stripe Connect, it's also possible to set a per-request key and/or account:

require "stripe"

Stripe::Charge.list(
  {},
  {
    api_key: "sk_test_...",
    stripe_account: "acct_...",
    stripe_version: "2018-02-28",
  }
)

Stripe::Charge.retrieve(
  "ch_18atAXCdGbJFKhCuBAa4532Z",
  {
    api_key: "sk_test_...",
    stripe_account: "acct_...",
    stripe_version: "2018-02-28",
  }
)

Stripe::Charge.retrieve(
  {
    id: "ch_18atAXCdGbJFKhCuBAa4532Z",
    expand: %w(balance_transaction)
  },
  {
    stripe_version: "2018-02-28",
    api_key: "sk_test_...",
  }
)

Get access to response objects by initializing a client and using its request method:

client = Stripe::StripeClient.new
charge, resp = client.request do
  Stripe::Charge.retrieve(
    "ch_18atAXCdGbJFKhCuBAa4532Z",
  )
end
puts resp.request_id

A proxy can be configured with Stripe.proxy:

Stripe.proxy = "https://user:[email protected]:1234"

By default, the library will use the API version pinned to the account making a request. This can be overridden with this global option:

Stripe.api_version = "2018-02-28"

See versioning in the API reference for more information.

By default, the library will use its own internal bundle of known CA certificates, but it's possible to configure your own:

Stripe.ca_bundle_path = "path/to/ca/bundle"

You can enable automatic retries on requests that fail due to a transient problem by configuring the maximum number of retries:

Stripe.max_network_retries = 2

Various errors can trigger a retry, like a connection error or a timeout, and also certain API responses like HTTP status 409 Conflict.

Idempotency keys are added to requests to guarantee that retries are safe.

Open and read timeouts are configurable:

Stripe.open_timeout = 30 // in seconds
Stripe.read_timeout = 80

Please take care to set conservative read timeouts. Some API requests can take some time, and a short timeout increases the likelihood of a problem within our servers.

The library can be configured to emit logging that will give you better insight into what it's doing. The info logging level is usually most appropriate for production use, but debug is also available for more verbosity.

There are a few options for enabling it:

1. Set the environment variable STRIPE_LOG to the value debug or info:

   $ export STRIPE_LOG=info

2. Set Stripe.log_level:

   Stripe.log_level = Stripe::LEVEL_INFO

If you're writing a plugin that uses the library, we'd appreciate it if you identified using #set_app_info:

Stripe.set_app_info("MyAwesomePlugin", version: "1.2.34", url: "https://myawesomeplugin.info");

This information is passed along when the library makes calls to the Stripe API.

By default, the library sends request latency telemetry to Stripe. These numbers help Stripe improve the overall latency of its API for all users.

You can disable this behavior if you prefer:

Stripe.enable_telemetry = false

The test suite depends on stripe-mock, so make sure to fetch and run it from a background terminal (stripe-mock's README also contains instructions for installing via Homebrew and other methods):

go get -u github.com/stripe/stripe-mock
stripe-mock

Run all tests:

bundle exec rake test

Run a single test suite:

bundle exec ruby -Ilib/ test/stripe/util_test.rb

Run a single test:

bundle exec ruby -Ilib/ test/stripe/util_test.rb -n /should.convert.names.to.symbols/

Run the linter:

bundle exec rake rubocop

Update bundled CA certificates from the Mozilla cURL release:

bundle exec rake update_certs

Update the bundled stripe-mock by editing the version number found in .travis.yml.
