An index and topic collection covering webhook delivery, ingestion, transformation, retry, and inspection APIs. Webhooks are the dominant HTTP pattern for asynchronous, event-driven integration between SaaS platforms — providers POST events to consumer endpoints, and consumers must reliably receive, verify, persist, and process those deliveries. This collection includes purpose-built webhook gateways like Hookdeck and ngrok, webhook inspection tools like Beeceptor and Webhook.site, durable event platforms like Inngest and Trigger.dev, automation hubs that expose webhook triggers (Zapier, n8n, Make, Pipedream, IFTTT, Integrately), cloud event buses (Amazon EventBridge, SNS, SQS, Azure Event Grid), and major webhook-emitting providers (Stripe, GitHub, Shopify, Twilio, SendGrid, Slack) whose webhook surfaces define the practices the rest of the ecosystem builds on.

## Use cases (7)

- **Receiving Stripe Payment Events** — E-commerce and SaaS applications subscribe to Stripe webhook events (invoice.paid, customer.subscription.updated) to keep billing state in sync with Stripe and trigger fulfillment.
- **GitHub CI/CD Automation** — Engineering teams use GitHub webhook events (push, pull_request, release) to trigger CI/CD pipelines, ChatOps notifications, and security scanning workflows.
- **Shopify Order Fan-Out** — Merchants use webhook gateways to fan out Shopify order events to fulfillment, accounting, marketing, and analytics consumers with per-destination retry isolation.
- **Local Webhook Development with Tunnels** — Developers use ngrok or smee.io to receive production-style webhook traffic on localhost during integration development, replaying captured requests to iterate on consumer logic.
- **Webhook Observability and Replay** — Operations teams use webhook gateways and inspection tools to monitor delivery success rates, alert on consumer failures, and replay missed or failed deliveries from history.
- **No-Code Webhook Automation** — Business users use Zapier, Make, n8n, IFTTT, and Pipedream to wire webhook events from one SaaS app into actions in another without writing code.
- **Event-Driven Cloud Fan-Out** — Cloud teams use Amazon EventBridge, SNS, and SQS to fan webhook deliveries out to multiple subscribers (Lambdas, queues, HTTP endpoints) with at-least-once delivery guarantees.
