StripePlugin

StripePlugin

Plugin to enable payments through Stripe via the Payment Intents API.

Requirements

1. You will need to create a Stripe account and get your secret key in the dashboard.

2. Create a webhook endpoint in the Stripe dashboard (Developers -> Webhooks, “Add an endpoint”) which listens to the payment_intent.succeeded and payment_intent.payment_failed events. The URL should be https://my-server.com/payments/stripe, where my-server.com is the host of your Vendure server. Note: for local development, you’ll need to use the Stripe CLI to test your webhook locally. See the local development section below.

3. Get the signing secret for the newly created webhook.

4. Install the Payments plugin and the Stripe Node library:

   yarn add @vendure/payments-plugin stripe

   or

   npm install @vendure/payments-plugin stripe

Setup

1. Add the plugin to your VendureConfig plugins array:

   import { StripePlugin } from '@vendure/payments-plugin/package/stripe';
   
   // ...
   
   plugins: [
     StripePlugin.init({
       apiKey: process.env.YOUR_STRIPE_SECRET_KEY,
       webhookSigningSecret: process.env.YOUR_STRIPE_WEBHOOK_SIGNING_SECRET,
       // This prevents different customers from using the same PaymentIntent
       storeCustomersInStripe: true,
     }),
   ]
   

2. Create a new PaymentMethod in the Admin UI, and select “Stripe payments” as the handler.

Storefront usage

The plugin is designed to work with the Custom payment flow. In this flow, Stripe provides libraries which handle the payment UI and confirmation for you. You can install it in your storefront project with:

yarn add @stripe/stripe-js
# or
npm install @stripe/stripe-js

If you are using React, you should also consider installing @stripe/react-stripe-js, which is a wrapper around Stripe Elements.

The high-level workflow is:

1. Create a “payment intent” on the server by executing the createStripePaymentIntent mutation which is exposed by this plugin.
2. Use the returned client secret to instantiate the Stripe Payment Element:

   import { Elements } from '@stripe/react-stripe-js';
   import { loadStripe, Stripe } from '@stripe/stripe-js';
   import { CheckoutForm } from './CheckoutForm';
   
   const stripePromise = getStripe('pk_test_....wr83u');
   
   type StripePaymentsProps = {
     clientSecret: string;
     orderCode: string;
   }
   
   export function StripePayments({ clientSecret, orderCode }: StripePaymentsProps) {
     const options = {
       // passing the client secret obtained from the server
       clientSecret,
     }
     return (
       <Elements stripe={stripePromise} options={options}>
         <CheckoutForm orderCode={orderCode} />
       </Elements>
     );
   }
   

   // CheckoutForm.tsx
   import { useStripe, useElements, PaymentElement } from '@stripe/react-stripe-js';
   import { FormEvent } from 'react';
   
   export const CheckoutForm = ({ orderCode }: { orderCode: string }) => {
     const stripe = useStripe();
     const elements = useElements();
   
     const handleSubmit = async (event: FormEvent) => {
       // We don't want to let default form submission happen here,
       // which would refresh the page.
       event.preventDefault();
   
       if (!stripe || !elements) {
         // Stripe.js has not yet loaded.
         // Make sure to disable form submission until Stripe.js has loaded.
         return;
       }
   
       const result = await stripe.confirmPayment({
         //`Elements` instance that was used to create the Payment Element
         elements,
         confirmParams: {
           return_url: location.origin + `/checkout/confirmation/${orderCode}`,
         },
       });
   
       if (result.error) {
         // Show error to your customer (for example, payment details incomplete)
         console.log(result.error.message);
       } else {
         // Your customer will be redirected to your `return_url`. For some payment
         // methods like iDEAL, your customer will be redirected to an intermediate
         // site first to authorize the payment, then redirected to the `return_url`.
       }
     };
   
     return (
       <form onSubmit={handleSubmit}>
         <PaymentElement />
         <button disabled={!stripe}>Submit</button>
       </form>
     );
   };
   

3. Once the form is submitted and Stripe processes the payment, the webhook takes care of updating the order without additional action in the storefront. As in the code above, the customer will be redirected to /checkout/confirmation/${orderCode}.

Local development

1. Download & install the Stripe CLI: https://stripe.com/docs/stripe-cli
2. From your Stripe dashboard, go to Developers -> Webhooks and click “Add an endpoint” and follow the instructions under “Test in a local environment”.
3. The Stripe CLI command will look like

   stripe listen --forward-to localhost:3000/payments/stripe
   

4. The Stripe CLI will create a webhook signing secret you can then use in your config of the StripePlugin.
