Go Stripe

Summary

The official Stripe Go client library.

Versioning

Each revision of the binding is tagged and the version is updated accordingly.

Given Go's lack of built-in versioning, it is highly recommended you use a package management tool in order to ensure a newer version of the binding does not affect backwards compatibility.

To see the list of past versions, run git tag. To manually get an older version of the client, clone this repo, checkout the specific tag and build the library:

git clone https://github.com/stripe/stripe-go.git
cd stripe
git checkout api_version_tag
make build

For more details on changes between versions, see the binding changelog and API changelog.

Installation

go get github.com/stripe/stripe-go

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{
	Balance: -123,
	Desc:  "Stripe Developer",
	Email: "[email protected]",
}
params.SetSource(&stripe.CardParams{
	Name:   "Go Stripe",
	Number: "378282246310005",
	Month:  "06",
	Year:   "15",
})

customer, err := customer.New(params)

Charges

params := &stripe.ChargeListParams{Customer: customer.Id}
params.Filters.AddFilter("include[]", "", "total_count")

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

i := charge.List(params)
for i.Next() {
  charge := i.Charge()
}

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

Events

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

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

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

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

Connect Flows

If you're using an access token you will need to use a client. Simply pass the access token value as the tok when initializing the client.

import (
  "github.com/stripe/stripe-go"
  "github.com/stripe/stripe-go/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"

    "appengine"
    "appengine/urlfetch"
    
    "github.com/stripe/stripe-go/client"
)

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

    sc := &client.API{}
    backends := stripe.Backends{
        API: stripe.BackendConfiguration{
            stripe.APIBackend, "https://api.stripe.com/v1", httpClient},
        Uploads: stripe.BackendConfiguration{
            stripe.UploadsBackend, "https://uploads.stripe.com/v1", httpClient},
    }
    sc.Init("sk_live_key", &backends)
    
    fmt.Fprintf(w, "Ready to make calls to the Stripe API")
}

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"
  "github.com/stripe/stripe-go/$resource$"
)

// 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
err := $resource$.Del(id)

// 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 the client.API. This allows you to create as many clients as needed, each with their own individual key.

import (
  "github.com/stripe/stripe-go"
  "github.com/stripe/stripe-go/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
err := sc.$Resource$s.Del(id)

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

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

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

For running additional tests, follow the steps below:

Set the STRIPE_KEY environment variable to match your test private key, then run make test:

STRIPE_KEY=YOUR_API_KEY make test

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