The official Stripe Go client library.
- Go 1.15 or later
Make sure your project is using Go Modules (it will have a go.mod file in its
root if it already is):
go mod initThen, reference stripe-go in a Go program with import:
import (
"github.com/stripe/stripe-go/v78"
"github.com/stripe/stripe-go/v78/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/v78For a comprehensive list of examples, check out the API documentation.
See video demonstrations covering how to use the library.
For details on all the functionality in this library, see the Go documentation.
Below are a few simple examples:
params := &stripe.CustomerParams{
Description: stripe.String("Stripe Developer"),
Email: stripe.String("[email protected]"),
PreferredLocales: stripe.StringSlice([]string{"en", "es"}),
}
c, err := customer.New(params)params := &stripe.PaymentIntentListParams{
Customer: stripe.String(customer.ID),
}
i := paymentintent.List(params)
for i.Next() {
pi := i.PaymentIntent()
}
if err := i.Err(); err != nil {
// handle
}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.
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/v78"
"github.com/stripe/stripe-go/v78/client"
)
stripe := &client.API{}
stripe.Init("access_token", nil)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/v78"
"github.com/stripe/stripe-go/v78/client"
)
func handler(w http.ResponseWriter, r *http.Request) {
c := appengine.NewContext(r)
httpClient := urlfetch.Client(c)
sc := client.New("sk_test_123", stripe.NewBackends(httpClient))
params := &stripe.CustomerParams{
Description: stripe.String("Stripe Developer"),
Email: stripe.String("[email protected]"),
}
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)
}While some resources may contain more/less APIs, the following pattern is
applied throughout the library for a given $resource$:
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/v78"
"github.com/stripe/stripe-go/v78/$resource$"
)
// Setup
stripe.Key = "sk_key"
// Set backend (optional, useful for mocking)
// stripe.SetBackend("api", backend)
// Create
resource, err := $resource$.New(&stripe.$Resource$Params{})
// Get
resource, err = $resource$.Get(id, &stripe.$Resource$Params{})
// Update
resource, err = $resource$.Update(id, &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
}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/v78"
"github.com/stripe/stripe-go/v78/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(id, &stripe.$Resource$Params{})
// Delete
$resource$Deleted, 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
}Use LastResponse on any APIResource to look at the API response that
generated the current object:
c, err := coupon.New(...)
requestID := coupon.LastResponse.RequestIDSimilarly, 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.
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/v78"
"github.com/stripe/stripe-go/v78/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(...)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.
All expandable objects in stripe-go take the form of a
full resource struct, but unless expansion is requested, only the ID field of
that struct is populated. Expansion is requested by calling AddExpand on
parameter structs. For example:
//
// *Without* expansion
//
c, _ := charge.Get("ch_123", nil)
c.Customer.ID // Only ID is populated
c.Customer.Name // All other fields are always empty
//
// With expansion
//
p := &stripe.ChargeParams{}
p.AddExpand("customer")
c, _ = charge.Get("ch_123", p)
c.Customer.ID // ID is still available
c.Customer.Name // Name is now also available (if it had a value)stripe-go is a typed library and it supports all public properties or parameters.
Stripe sometimes launches private beta features which introduce new properties or parameters that are not immediately public. These will not have typed accessors in the stripe-go library but can still be used.
To pass undocumented parameters to Stripe using stripe-go you need to use the AddExtra() method, as shown below:
params := &stripe.CustomerParams{
Email: stripe.String("[email protected]")
}
params.AddExtra("secret_feature_enabled", "true")
params.AddExtra("secret_parameter[primary]","primary value")
params.AddExtra("secret_parameter[secondary]","secondary value")
customer, err := customer.Create(params)You can access undocumented properties returned by Stripe by querying the raw response JSON object. An example of this is shown below:
customer, _ = customer.Get("cus_1234", nil);
var rawData map[string]interface{}
_ = json.Unmarshal(customer.LastResponse.RawJSON, &rawData)
secret_feature_enabled, _ := string(rawData["secret_feature_enabled"].(bool))
secret_parameter, ok := rawData["secret_parameter"].(map[string]interface{})
if ok {
primary := secret_parameter["primary"].(string)
secondary := secret_parameter["secondary"].(string)
} Stripe can optionally sign the webhook events it sends to your endpoint, allowing you to validate that they were not sent by a third-party. You can read more about it here.
You can use stripe.webhook.GenerateTestSignedPayload to mock webhook events that come from Stripe:
payload := map[string]interface{}{
"id": "evt_test_webhook",
"object": "event",
"api_version": stripe.APIVersion,
}
testSecret := "whsec_test_secret"
payloadBytes, err := json.Marshal(payload)
signedPayload := webhook.GenerateTestSignedPayload(&webhook.UnsignedPayload{Payload: payloadBytes, Secret: testSecret})
event, err := webhook.ConstructEvent(signedPayload.Payload, signedPayload.Header, signedPayload.Secret)
if event.ID == payload["id"] {
// Do something with the mocked signed event
} else {
// Handle invalid event payload
}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.
By default, the library sends telemetry to Stripe regarding request latency and feature usage. These numbers help Stripe improve the overall latency of its API for all users, and improve popular features.
You can disable this behavior if you prefer:
config := &stripe.BackendConfig{
EnableTelemetry: stripe.Bool(false),
}To mock a Stripe client for a unit tests using GoMock:
- Generate a
Backendtype mock.
mockgen -destination=mocks/backend.go -package=mocks github.com/stripe/stripe-go/v78 Backend
- Use the
Backendmock to initialize and call methods on the client.
import (
"example/hello/mocks"
"testing"
"github.com/golang/mock/gomock"
"github.com/stretchr/testify/assert"
"github.com/stripe/stripe-go/v78"
"github.com/stripe/stripe-go/v78/account"
)
func UseMockedStripeClient(t *testing.T) {
// Create a mock controller
mockCtrl := gomock.NewController(t)
defer mockCtrl.Finish()
// Create a mock stripe backend
mockBackend := mocks.NewMockBackend(mockCtrl)
client := account.Client{B: mockBackend, Key: "key_123"}
// Set up a mock call
mockBackend.EXPECT().Call("GET", "/v1/accounts/acc_123", gomock.Any(), gomock.Any(), gomock.Any()).
// Return nil error
Return(nil).
Do(func(method string, path string, key string, params stripe.ParamsContainer, v *stripe.Account) {
// Set the return value for the method
*v = stripe.Account{
ID: "acc_123",
}
}).Times(1)
// Call the client method
acc, _ := client.GetByID("acc_123", nil)
// Asset the result
assert.Equal(t, acc.ID, "acc_123")
}Stripe has features in the beta phase that can be accessed via the beta version of this package.
We would love for you to try these and share feedback with us before these features reach the stable phase.
To install a beta version of stripe-go use the commit notation of the go get command to point to a beta tag:
go get -u github.com/stripe/stripe-go/[email protected]
Note There can be breaking changes between beta versions.
We highly recommend keeping an eye on when the beta feature you are interested in goes from beta to stable so that you can move from using a beta version of the SDK to the stable version.
If your beta feature requires a Stripe-Version header to be sent, set the stripe.APIVersion field using the stripe.AddBetaVersion function to set it:
Note The
APIVersioncan only be set in beta versions of the library.
stripe.AddBetaVersion("feature_beta", "v3")New features and bug fixes are released on the latest major version of the Stripe Go client library. If you are on an older major version, we recommend that you upgrade to the latest in order to use the new features and bug fixes including those for security vulnerabilities. Older major versions of the package will continue to be available for use, but will not be receiving any updates.
Pull requests from the community are welcome. If you submit one, please keep the following guidelines in mind:
- Code must be
go fmtcompliant. - All types, structs and funcs should be documented.
- Ensure that
make testsucceeds.
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.
