Webhook Processor

Overview

This skill helps you build production-grade webhook ingestion endpoints that accept incoming HTTP callbacks, verify their authenticity, and process them reliably with exponential backoff retries and dead letter queues. It covers signature validation, idempotency keys, and graceful failure handling.

Instructions

1. Scaffold the webhook endpoint

Create an HTTP endpoint that accepts POST requests. Immediately return a 200 status before processing — webhook senders expect fast acknowledgment.

// webhook-receiver.ts
import express from "express";
import crypto from "crypto";
import { Queue } from "bullmq";

const app = express();
app.use(express.raw({ type: "application/json" }));
