Mastering Stripe API with JavaScript: A Comprehensive Guide
Written on
Chapter 1: Introduction to Stripe API
Stripe has evolved from a simple payment processor into a powerful platform shaping the future of commerce. For developers eager to explore the Stripe API with JavaScript, this guide provides a detailed walkthrough!
In this tutorial, we'll cover the process of creating test products in a Stripe test account and how to retrieve product information through JavaScript requests, allowing for experimentation in a secure environment.
Section 1.1: Setting Up Your Stripe Account
To begin, you'll need to create a free Stripe account. Head over to their website to sign up. Once your account is set up, you will have access to a dashboard in Test mode (look for the "Test mode" toggle, likely located on the right side of your dashboard). With this test account, you can freely experiment with the API.
Next, locate your secret key by navigating to the Developers tab and then selecting API keys. You will find both your publishable key and your secret key here. Be sure to keep your secret key safe, as it will be essential for connecting to your account via code. Note: Even in a test environment, do not share your secret key with anyone!
Subsection 1.1.1: Creating Products
To add new products, click on the Products tab in your dashboard. For this tutorial, create one to four test products with names like "Test Product 1" and set their prices to $0.00. Remember, you can modify this information later if necessary.
Section 1.2: Connecting Code to Your Stripe Account
Open your preferred code editor and create a new JavaScript file, such as stripe_test.js. Ensure Node.js is installed on your machine so you can run the file using the command line (e.g., node stripe_test.js).
Now, let’s write some code! Begin by installing the required dependencies by typing npm install stripe in your command line. Then, in your JavaScript file, include the Stripe library with the following line:
const Stripe = require("stripe");
Next, store your secret key in a variable (see the important note below about key storage):
const SECRET_KEY = 'sk_test_51K8pTLKS5...........';
Important note — it’s recommended to store your secret keys in a .env file instead of hardcoding them. For this tutorial, we are simply experimenting locally, but for production code, always use a secure method for key storage. If you suspect your secret key has been compromised, utilize the "roll key" feature to generate a new key.
Now, find the ID of one of the products you created. Simply click on the product in your Stripe dashboard to view its ID and store it in your code:
const PRODUCT_ID = 'prod_KoWtM......';
And now for retrieving product information...
Chapter 2: Retrieving Product Information
To fetch details about the specific product you stored in PRODUCT_ID, you can use the following async function:
const getSingleProduct = async (stripe) => {
const product = await stripe.products.retrieve(PRODUCT_ID);
console.log(product);
}
getSingleProduct(stripe);
Upon running your program, the console should display an object containing product details such as its name and associated images.
To retrieve all products listed in your dashboard, use:
const getAllProducts = async (stripe) => {
const product = await stripe.products.list();
console.log(product);
}
getAllProducts(stripe);
If you're interested in displaying just a few products (for example, three), you can adjust the request like this:
const getThreeProducts = async (stripe) => {
const product = await stripe.products.list({
limit: 3});
console.log(product);
}
getThreeProducts(stripe);
This guide aimed to introduce the basics of using the Stripe API with JavaScript in an approachable manner. The Stripe API offers extensive capabilities beyond what we've explored here, but this serves as a solid starting point.
