Go Stripe

GoDoc Build Status Coverage Status

The official Stripe Go client library.

Installation

Make sure your project is using Go Modules (it will have a go.mod file in its root if it already is):

go mod init

Then, reference stripe-go in a Go program with import:

import (
    "github.com/stripe/stripe-go/v71"
    "github.com/stripe/stripe-go/v71/customer"
)

Run any of the normal go commands (build/install/test). The Go toolchain will resolve and fetch the stripe-go module automatically.

Alternatively, you can also explicitly go get the package into a project:

go get -u github.com/stripe/stripe-go/v71

Documentation

For a comprehensive list of examples, check out the API documentation.

For details on all the functionality in this library, see the GoDoc documentation.

Below are a few simple examples:

Customers

params := &stripe.CustomerParams{
    Description: stripe.String("Stripe Developer"),
    Email:       stripe.String("gostripe@stripe.com"),
}

customer, err := customer.New(params)

PaymentIntents

params := &stripe.PaymentIntentListParams{
    Customer: stripe.String(customer.ID),
}

// set this so you can easily retry your request in case of a timeout
params.Params.IdempotencyKey = stripe.NewIdempotencyKey()

i := paymentintent.List(params)
for i.Next() {
    pi := i.PaymentIntent()
}

if err := i.Err(); err != nil {
    // handle
}

Events

i := event.List(nil)
for i.Next() {
    e := i.Event()

    // access event data via e.GetObjectValue("resource_name_based_on_type", "resource_property_name")
    // alternatively you can access values via e.Data.Object["resource_name_based_on_type"].(map[string]interface{})["resource_property_name"]

    // access previous attributes via e.GetPreviousValue("resource_name_based_on_type", "resource_property_name")
    // alternatively you can access values via e.Data.PrevPreviousAttributes["resource_name_based_on_type"].(map[string]interface{})["resource_property_name"]
}

Alternatively, you can use the event.Data.Raw property to unmarshal to the appropriate struct.

Authentication with Connect

There are two ways of authenticating requests when performing actions on behalf of a connected account, one that uses the Stripe-Account header containing an account's ID, and one that uses the account's keys. Usually the former is the recommended approach. See the documentation for more information.

To use the Stripe-Account approach, use SetStripeAccount() on a ListParams or Params class. For example:

// For a list request
listParams := &stripe.CustomerListParams{}
listParams.SetStripeAccount("acct_123")
// For any other kind of request
params := &stripe.CustomerParams{}
params.SetStripeAccount("acct_123")

To use a key, pass it to API's Init function:


import (
    "github.com/stripe/stripe-go/v71"
    "github.com/stripe/stripe-go/v71/client"
)

stripe := &client.API{}
stripe.Init("access_token", nil)

Google AppEngine

If you're running the client in a Google AppEngine environment, you'll need to create a per-request Stripe client since the http.DefaultClient is not available. Here's a sample handler:

import (
    "fmt"
    "net/http"

    "google.golang.org/appengine"
    "google.golang.org/appengine/urlfetch"

    "github.com/stripe/stripe-go/v71"
    "github.com/stripe/stripe-go/v71/client"
)

func handler(w http.ResponseWriter, r *http.Request) {
        c := appengine.NewContext(r)
        httpClient := urlfetch.Client(c)

        sc := stripeClient.New("sk_test_123", stripe.NewBackends(httpClient))

        params := &stripe.CustomerParams{
            Description: stripe.String("Stripe Developer"),
            Email:       stripe.String("gostripe@stripe.com"),
        }
        customer, err := sc.Customers.New(params)
        if err != nil {
            fmt.Fprintf(w, "Could not create customer: %v", err)
        }
        fmt.Fprintf(w, "Customer created: %v", customer.ID)
}

Usage

While some resources may contain more/less APIs, the following pattern is applied throughout the library for a given $resource$:

Without a Client

If you're only dealing with a single key, you can simply import the packages required for the resources you're interacting with without the need to create a client.

import (
    "github.com/stripe/stripe-go/v71"
    "github.com/stripe/stripe-go/v71/$resource$"
)

// Setup
stripe.Key = "sk_key"

stripe.SetBackend("api", backend) // optional, useful for mocking

// Create
$resource$, err := $resource$.New(stripe.$Resource$Params)

// Get
$resource$, err := $resource$.Get(id, stripe.$Resource$Params)

// Update
$resource$, err := $resource$.Update(stripe.$Resource$Params)

// Delete
resourceDeleted, err := $resource$.Del(id, stripe.$Resource$Params)

// List
i := $resource$.List(stripe.$Resource$ListParams)
for i.Next() {
    $resource$ := i.$Resource$()
}

if err := i.Err(); err != nil {
    // handle
}

With a Client

If you're dealing with multiple keys, it is recommended you use client.API. This allows you to create as many clients as needed, each with their own individual key.

import (
    "github.com/stripe/stripe-go/v71"
    "github.com/stripe/stripe-go/v71/client"
)

// Setup
sc := &client.API{}
sc.Init("sk_key", nil) // the second parameter overrides the backends used if needed for mocking

// Create
$resource$, err := sc.$Resource$s.New(stripe.$Resource$Params)

// Get
$resource$, err := sc.$Resource$s.Get(id, stripe.$Resource$Params)

// Update
$resource$, err := sc.$Resource$s.Update(stripe.$Resource$Params)

// Delete
resourceDeleted, err := sc.$Resource$s.Del(id, stripe.$Resource$Params)

// List
i := sc.$Resource$s.List(stripe.$Resource$ListParams)
for i.Next() {
    resource := i.$Resource$()
}

if err := i.Err(); err != nil {
    // handle
}

Accessing the Last Response

Use LastResponse on any APIResource to look at the API response that generated the current object:

coupon, err := coupon.New(...)
requestID := coupon.LastResponse.RequestID

Similarly, for List operations, the last response is available on the list object attached to the iterator:

it := coupon.List(...)
for it.Next() {
    // Last response *NOT* on the individual iterator object
    it.Coupon().LastResponse // wrong

    // But rather on the list object, also accessible through the iterator
    requestID := it.CouponList().LastResponse.RequestID
}

See the definition of APIResponse for available fields.

Note that where API resources are nested in other API resources, only LastResponse on the top-level resource is set.

Automatic Retries

The library automatically retries requests on intermittent failures like on a connection error, timeout, or on certain API responses like a status 409 Conflict. Idempotency keys are always added to requests to make any such subsequent retries safe.

By default, it will perform up to two retries. That number can be configured with MaxNetworkRetries:

import (
    "github.com/stripe/stripe-go/v71"
    "github.com/stripe/stripe-go/v71/client"
)

config := &stripe.BackendConfig{
    MaxNetworkRetries: stripe.Int64(0), // Zero retries
}

sc := &client.API{}
sc.Init("sk_key", &stripe.Backends{
    API:     stripe.GetBackendWithConfig(stripe.APIBackend, config),
    Uploads: stripe.GetBackendWithConfig(stripe.UploadsBackend, config),
})

coupon, err := sc.Coupons.New(...)

Configuring Logging

By default, the library logs error messages only (which are sent to stderr). Configure default logging using the global DefaultLeveledLogger variable:

stripe.DefaultLeveledLogger = &stripe.LeveledLogger{
    Level: stripe.LevelInfo,
}

Or on a per-backend basis:

config := &stripe.BackendConfig{
    LeveledLogger: &stripe.LeveledLogger{
        Level: stripe.LevelInfo,
    },
}

It's possible to use non-Stripe leveled loggers as well. Stripe expects loggers to comply to the following interface:

type LeveledLoggerInterface interface {
    Debugf(format string, v ...interface{})
    Errorf(format string, v ...interface{})
    Infof(format string, v ...interface{})
    Warnf(format string, v ...interface{})
}

Some loggers like Logrus and Zap's SugaredLogger support this interface out-of-the-box so it's possible to set DefaultLeveledLogger to a *logrus.Logger or *zap.SugaredLogger directly. For others it may be necessary to write a thin shim layer to support them.

Writing a Plugin

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

stripe.SetAppInfo(&stripe.AppInfo{
    Name:    "MyAwesomePlugin",
    URL:     "https://myawesomeplugin.info",
    Version: "1.2.34",
})

This information is passed along when the library makes calls to the Stripe API. Note that while Name is always required, URL and Version are optional.

Request latency telemetry

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:

config := &stripe.BackendConfig{
    EnableTelemetry: stripe.Bool(false),
}

Development

Pull requests from the community are welcome. If you submit one, please keep the following guidelines in mind:

  1. Code must be go fmt compliant.
  2. All types, structs and funcs should be documented.
  3. Ensure that make test succeeds.

Test

The test suite needs testify's require package to run:

github.com/stretchr/testify/require

Before running the tests, make sure to grab all of the package's dependencies:

go get -t -v

It also 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:

make test

Run tests for one package:

go test ./invoice

Run a single test:

go test ./invoice -run TestInvoiceGet

For any requests, bug or comments, please open an issue or submit a pull request.
