# Webhooks > 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 recei...

**Signature Verification and Security**: Webhook providers sign payloads with HMAC-SHA256, Ed25519, or asymmetric keys so consumers can verify authenticity, prevent replay attacks, and reject forged requests. - **Webhook Inspection and Debugging**: Tools like Beeceptor, Webhook.site, and ngrok give developers public URLs for local endpoints and human-readable logs of inbound webhook traffic for debugging and replay. - **Webhook Gateways and Fan-Out**: Gateway platforms like Hookdeck and Convoy sit between producers and consumers to centralize signing, filtering, transformation, fan-out to multiple destinations, and observability. - **Event Filtering and Transformation**: Webhook platforms let teams filter events by type or payload content, transform JSON payloads inline, and route the result to specific consumer endpoints or queues. - **Local Tunneling for Development**: Tunneling tools like ngrok and smee.io expose localhost endpoints to public URLs so developers can receive and debug real webhook traffic during local development. - **Durable Event Workflows**: Platforms like Inngest and Trigger.dev treat webhook deliveries as the entry point to durable, retryable, multi-step workflows with built-in scheduling, queues, and step-level retries. ## Use Cases - **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. ## Related Areas -
