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.
- 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 customers
Stripe::Customer.list()
# retrieve single customer
Stripe::Customer.retrieve("cus_123456789")
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::Customer.list(
{},
{
api_key: "sk_test_...",
stripe_account: "acct_...",
stripe_version: "2018-02-28",
}
)
Stripe::Customer.retrieve(
"cus_123456789",
{
api_key: "sk_test_...",
stripe_account: "acct_...",
stripe_version: "2018-02-28",
}
)
Stripe::Customer.retrieve(
{
id: "cus_123456789",
expand: %w(balance_transaction)
},
{
stripe_version: "2018-02-28",
api_key: "sk_test_...",
}
)
Stripe::Customer.capture(
"cus_123456789",
{},
{
stripe_version: "2018-02-28",
api_key: "sk_test_...",
}
)
Keep in mind that there are different method signatures depending on the action:
- When operating on a collection (e.g.
.list
,.create
) the method signature ismethod(params, opts)
. - When operating on resource (e.g.
.capture
,.update
) the method signature ismethod(id, params, opts)
. - One exception is that
retrieve
, despite being an operation on a resource, has the signatureretrieve(id, opts)
. In addition, it will accept a Hash for theid
param but will extract theid
key out and use the others as options.
Get access to response objects by initializing a client and using its request
method:
client = Stripe::StripeClient.new
customer, resp = client.request do
Stripe::Customer.retrieve("cus_123456789",)
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:
-
Set the environment variable
STRIPE_LOG
to the valuedebug
orinfo
:$ export STRIPE_LOG=info
-
Set
Stripe.log_level
:Stripe.log_level = Stripe::LEVEL_INFO
The library has various hooks that user code can tie into by passing a block to
Stripe::Instrumentation.subscribe
to be notified about specific events.
Invoked when an HTTP request starts. Receives RequestBeginEvent
with the
following properties:
method
: HTTP method. (Symbol
)path
: Request path. (String
)user_data
: A hash on which users can set arbitrary data, and which will be passed through torequest_end
invocations. This could be used, for example, to assign unique IDs to each request, and it'd work even if many requests are running in parallel. All subscribers share the same object for any particular request, so they must be careful to use unique keys that will not conflict with other subscribers. (Hash
)
Invoked when an HTTP request finishes, regardless of whether it terminated with
a success or error. Receives RequestEndEvent
with the following properties:
duration
: Request duration in seconds. (Float
)http_status
: HTTP response code (Integer
) if available, ornil
in case of a lower level network error.method
: HTTP method. (Symbol
)num_retries
: The number of retries. (Integer
)path
: Request path. (String
)user_data
: A hash on which users may have set arbitrary data inrequest_begin
. See above for more information. (Hash
)
For example:
Stripe::Instrumentation.subscribe(:request_end) do |request_event|
tags = {
method: request_event.method,
resource: request_event.path.split("/")[2],
code: request_event.http_status,
retries: request_event.num_retries
}
StatsD.distribution('stripe_request', request_event.duration, tags: tags)
end
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
.
