Step by Step Guide to Building an Adobe Commerce API Integration in Go

Introduction

Hey there, fellow developer! Ready to dive into the world of Adobe Commerce API integration using Go? You're in for a treat. Adobe Commerce (formerly Magento) offers a powerful API that can supercharge your e-commerce projects. Let's get cracking!

Prerequisites

Before we jump in, make sure you've got:

• Go installed on your machine
• An Adobe Commerce account with API credentials
• A solid grasp of RESTful APIs

Got all that? Great! Let's move on.

Setting up the project

First things first, let's set up our Go project:

mkdir adobe-commerce-api
cd adobe-commerce-api
go mod init github.com/yourusername/adobe-commerce-api

Now, let's grab the dependencies we'll need:

go get github.com/go-resty/resty/v2

Authentication

Alright, time to get that access token. Adobe Commerce uses OAuth 2.0, so we'll need to implement that:

import (
    "github.com/go-resty/resty/v2"
)

func getAccessToken(clientID, clientSecret string) (string, error) {
    client := resty.New()
    resp, err := client.R().
        SetFormData(map[string]string{
            "grant_type":    "client_credentials",
            "client_id":     clientID,
            "client_secret": clientSecret,
        }).
        Post("https://your-store.com/oauth/token")

    // Handle the response and extract the access token
    // Don't forget to implement token refresh!
}

Making API requests

Now that we're authenticated, let's make some requests:

func getProduct(accessToken, productSKU string) (Product, error) {
    client := resty.New()
    resp, err := client.R().
        SetAuthToken(accessToken).
        Get("https://your-store.com/rest/V1/products/" + productSKU)

    // Parse the response and return the product
}

func createOrder(accessToken string, order Order) (string, error) {
    client := resty.New()
    resp, err := client.R().
        SetAuthToken(accessToken).
        SetBody(order).
        Post("https://your-store.com/rest/V1/orders")

    // Handle the response and return the order ID
}

Implementing key Adobe Commerce API endpoints

Let's implement some crucial endpoints:

Products API

func listProducts(accessToken string, pageSize, currentPage int) ([]Product, error) {
    // Implement product listing with pagination
}

func updateProduct(accessToken string, product Product) error {
    // Implement product update
}

Orders API

func getOrder(accessToken string, orderID string) (Order, error) {
    // Implement order retrieval
}

func cancelOrder(accessToken string, orderID string) error {
    // Implement order cancellation
}

Customers API

func createCustomer(accessToken string, customer Customer) (string, error) {
    // Implement customer creation
}

func updateCustomer(accessToken string, customerID string, customer Customer) error {
    // Implement customer update
}

Error handling and logging

Don't forget to implement robust error handling and logging:

import (
    "log"
)

func handleAPIError(err error) {
    log.Printf("API Error: %v", err)
    // Implement retry logic or graceful degradation
}

Testing the integration

Time to put our code to the test:

func TestGetProduct(t *testing.T) {
    // Implement unit test for getProduct function
}

func TestCreateOrder(t *testing.T) {
    // Implement integration test with Adobe Commerce sandbox
}

Best practices and optimization

To keep your integration running smoothly:

• Implement rate limiting to avoid hitting API limits
• Use goroutines for concurrent API calls (but be mindful of rate limits!)
• Cache frequently accessed data to reduce API calls

Conclusion

And there you have it! You've just built a solid Adobe Commerce API integration in Go. Remember, this is just the beginning – there's a whole world of e-commerce possibilities waiting for you to explore.

Keep experimenting, stay curious, and happy coding!
