Stripe Ruby Library
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.
Documentation
See the Ruby API docs.
Installation
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
Requirements
- Ruby 2.1+.
Bundler
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'
Usage
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",
)
Per-request Configuration
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_...'
}
)
Configuring a Client
While a default HTTP client is used by default, it's also possible to have the
library use any client supported by Faraday by initializing a
Stripe::StripeClient
object and giving it a connection:
conn = Faraday.new
client = Stripe::StripeClient.new(conn)
charge, resp = client.request do
Stripe::Charge.retrieve(
"ch_18atAXCdGbJFKhCuBAa4532Z",
)
end
puts resp.request_id
Configuring a proxy
A proxy can be configured with Stripe.proxy
:
Stripe.proxy = "https://user:pass@example.com:1234"
Configuring an API Version
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.
Configuring CA Bundles
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"
Configuring Automatic Retries
The library can be configured to automatically retry requests that fail due to an intermittent network problem:
Stripe.max_network_retries = 2
Idempotency keys are added to requests to guarantee that retries are safe.
Configuring Timeouts
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.
Logging
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:
-
Set the environment variable
STRIPE_LOG
to the valuedebug
orinfo
:$ export STRIPE_LOG=info
-
Set
Stripe.log_level
:Stripe.log_level = Stripe::LEVEL_INFO
Writing a Plugin
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.
Development
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
.
