The new home of Conversio's Shopify Go library.

Note: The library does not have implementations of all Shopify resources, but it is being used in production and should be stable for usage. PRs for new resources and endpoints are welcome, or you can simply implement some yourself as-you-go. See the section "Using your own models" for more info.

This library is tested automatically against the latest version of Go (currently 1.22) and the two previous versions (1.21, 1.20) but should also work with older versions.

$ go get github.com/bold-commerce/go-shopify/v4

import "github.com/bold-commerce/go-shopify/v4"

This gives you access to the goshopify package.

$ go get github.com/bold-commerce/go-shopify/v3

import "github.com/bold-commerce/go-shopify/v3"

This gives you access to the goshopify package.

$ go get github.com/bold-commerce/go-shopify

import "github.com/bold-commerce/go-shopify"

This gives you access to the goshopify package.

If you don't have an access token yet, you can obtain one with the oauth flow. Something like this will work:

// Create an app somewhere. app := goshopify.App{ ApiKey: "abcd", ApiSecret: "efgh", RedirectUrl: "https://example.com/shopify/callback", Scope: "read_products,read_orders", } // Create an oauth-authorize url for the app and redirect to it. // In some request handler, you probably want something like this: func MyHandler(w http.ResponseWriter, r *http.Request) { shopName := r.URL.Query().Get("shop") state := "nonce" authUrl := app.AuthorizeUrl(shopName, state) http.Redirect(w, r, authUrl, http.StatusFound) } // Fetch a permanent access token in the callback func MyCallbackHandler(w http.ResponseWriter, r *http.Request) { // Check that the callback signature is valid if ok, _ := app.VerifyAuthorizationURL(r.URL); !ok { http.Error(w, "Invalid Signature", http.StatusUnauthorized) return } query := r.URL.Query() shopName := query.Get("shop") code := query.Get("code") ctx := context.TODO() // adds context which will be used in GetAccessToken below token, err := app.GetAccessToken(ctx, shopName, code) // Do something with the token, like store it in a DB. }

With a permanent access token, you can make API calls like this:

// Create an app somewhere. app := goshopify.App{ ApiKey: "abcd", ApiSecret: "efgh", RedirectUrl: "https://example.com/shopify/callback", Scope: "read_products", } // Create a new API client client, err := goshopify.NewClient(app, "shopname", "token") // Fetch the number of products. numProducts, err := client.Product.Count(nil)

Private Shopify apps use basic authentication and do not require going through the OAuth flow. Here is an example:

// Create an app somewhere. app := goshopify.App{ ApiKey: "apikey", Password: "apipassword", } // Create a new API client (notice the token parameter is the empty string) client, err := goshopify.NewClient(app, "shopname", "") // Fetch the number of products. numProducts, err := client.Product.Count(nil)

When creating a client there are configuration options you can pass to NewClient. Simply use the last variadic param and pass in the built in options or create your own and manipulate the client. See options.go for more details.

Read more details on the Shopify API Versioning to understand the format and release schedules. You can use WithVersion to specify a specific version of the API. If you do not use this option you will be defaulted to the oldest stable API.

client, err := goshopify.NewClient(app, "shopname", "", goshopify.WithVersion("2019-04"))

Shopify Rate Limits their API and if this happens to you they will send a back off (usually 2s) to tell you to retry your request. To support this functionality seamlessly within the client a WithRetry option exists where you can pass an int of how many times you wish to retry per-request before returning an error. WithRetry additionally supports retrying HTTP503 errors.

client, err := goshopify.NewClient(app, "shopname", "", goshopify.WithRetry(3))

Most API functions take an options interface{} as parameter. You can use one from the library or create your own. For example, to fetch the number of products created after January 1, 2016, you can do:

// Create standard CountOptions date := time.Date(2016, time.January, 1, 0, 0, 0, 0, time.UTC) options := goshopify.CountOptions{createdAtMin: date} // Use the options when calling the API. numProducts, err := client.Product.Count(options)

The options are parsed with Google's go-querystring library so you can use custom options like this:

// Create custom options for the orders. // Notice the `url:"status"` tag options := struct { Status string `url:"status"` }{"any"} // Fetch the order count for orders with status="any" orderCount, err := client.Order.Count(options)

Not all endpoints are implemented right now. In those case, feel free to implement them and make a PR, or you can create your own struct for the data and use NewRequest with the API client. This is how the existing endpoints are implemented.

For example, let's say you want to fetch webhooks. There's a helper function Get specifically for fetching stuff so this will work:

// Declare a model for the webhook type Webhook struct { Id int `json:"id"` Address string `json:"address"` } // Declare a model for the resource root. type WebhooksResource struct { Webhooks []Webhook `json:"webhooks"` } func FetchWebhooks() ([]Webhook, error) { path := "admin/webhooks.json" resource := new(WebhooksResource) client, _ := goshopify.NewClient(app, "shopname", "token") // resource gets modified when calling Get err := client.Get(path, resource, nil) return resource.Webhooks, err }

In order to be sure that a webhook is sent from ShopifyApi you could easily verify it with the VerifyWebhookRequest method.

For example:

func ValidateWebhook(httpRequest *http.Request) (bool) { shopifyApp := goshopify.App{ApiSecret: "ratz"} return shopifyApp.VerifyWebhookRequest(httpRequest) }

docker and docker-compose must be installed

Using the make file is the easiest way to get started with the tests and wraps the manual steps below with easy to use make commands.

make && make test

• make or make container: default goal is to make the go-shopify:latest build container
• make test: run go test in the container
• make clean: deletes the go-shopify:latest image and coverage output
• make coverage: generates the coverage.html and opens it

To run the tests you will need the go-shopify:latest image built to run your tests, to do this run

docker-compose build test 

To run tests you can use run

docker-compose run --rm tests

To create a coverage profile run the following to generate a coverage.html

docker-compose run --rm dev sh -c 'go test -coverprofile=coverage.out ./... && go tool cover -html coverage.out -o coverage.html' 

When done testing and you want to cleanup simply run

docker image rm go-shopify:latest 

Read the docker-compose.yml and Dockerfile for further details.
