🎣 Webhooks

Create a secure webhook handler endpoint

Prompt Template

Create a POST endpoint on the "/webhook" route in [SOME WEB FRAMEWORK] to handle Stripe webhook events.
The handler should verify the webhook signature and handle the "checkout.session.completed" event.
Use the code below as a reference:


file_type_typescript src/index.ts
import { serve } from '@hono/node-server'
import { Hono } from 'hono'
import { HTTPException } from 'hono/http-exception';
import Stripe from 'stripe';
import 'dotenv/config'

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!);

const app = new Hono()

app.post('/webhook', async (c) => {
  const rawBody = await c.req.text();
  const signature = c.req.header('stripe-signature');

  let event;
  try {
    event = stripe.webhooks.constructEvent(rawBody, signature!, process.env.STRIPE_WEBHOOK_SECRET!);
  } catch (error: any) {
    console.error(`Webhook signature verification failed: ${error.message}`);
    throw new HTTPException(400)

  // Handle the checkout.session.completed event
  if (event.type === 'checkout.session.completed') {
    const session = event.data.object;

    // TODO Fulfill the purchase with your own business logic, for example:
    // Update Database with order details
    // Add credits to customer account
    // Send confirmation email
    // Print shipping label
    // Trigger order fulfillment workflow
    // Update inventory
    // Etc.

  return c.text('success');

const port = 3000
console.log(`Server is running on port ${port}`)
