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 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.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Webhooks

Each block below is one kind of artifact we hold for Webhooks. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

Notable capabilities this provider offers.

Webhook Delivery and Retries

Webhook platforms reliably deliver event payloads from producer APIs to consumer endpoints, with automatic retries, exponential backoff, and dead-letter queues to handle transie...

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 observabil...

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 r...

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON Schema 2

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

JSON Structure 2

JSON Structure captures the data shapes in a form built for tooling — a complement to JSON Schema that keeps the model machine-legible.

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Use Cases 7

What developers actually build with this provider — captured so the catalogue answers 'what is this for', not just 'what does this expose'.

What developers build with this provider.

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.

Integrations 8

Pre-built integrations with other platforms tell you where this provider already fits in a stack.

Pre-built integrations with other platforms and tools.

Hookdeck

Webhook gateway that ingests, verifies, persists, filters, transforms, and reliably delivers webhook events with retry, replay, and observability.

ngrok

Secure tunneling and ingress platform widely used by developers to expose local webhook endpoints to public URLs for development and debugging.

Beeceptor

Webhook inspection and mocking platform providing instant public endpoints to capture, inspect, and mock inbound HTTP and webhook traffic.

Inngest
