Hookdeck
Hookdeck is a Toronto-based webhook and event-infrastructure platform. The Hookdeck Event Gateway sits between webhook senders and your services to receive, verify, queue, retry, transform, filter, route, and observe events reliably at scale. Hookdeck exposes a fully versioned REST Admin API, a CLI for local development, language SDKs (TypeScript, Go, Python, .NET), a Terraform provider, and the open-source Outpost project for self-hostable outbound webhook delivery.
Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.
API Evangelist profiles Hookdeck the way a machine reads it — 95 machine-readable artifacts across 17 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Hookdeck scores 77.5/100 (exemplar), with a separate agent-readiness read of 53/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
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.

How we profile Hookdeck
Each block below is one kind of artifact we hold for Hookdeck. 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.
APIs 17
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Hookdeck Connections API
Create, update, list, archive, pause, and unpause connections. A connection routes events from a Source to a Destination and may carry rules (retry, alert, transform, filter, de...
Hookdeck Sources API
Manage sources — the upstream endpoints (webhook senders or push channels) that ingest events into Hookdeck. Sources support platform-specific verification (Stripe, GitHub, Twil...
Hookdeck Destinations API
Manage destinations — the downstream targets (HTTP endpoints, AWS SQS, Azure Service Bus, GCP Pub/Sub, Kafka, RabbitMQ, MongoDB, and more) where Hookdeck delivers events. Suppor...
Hookdeck Events API
List, retrieve, retry, mute, and inspect events and their delivery attempts. An event is any request Hookdeck received from a source; an attempt is each delivery try against a d...
Hookdeck Requests API
List and inspect raw requests received by Hookdeck. A request precedes events and is what gets accepted at the gateway boundary before verification, fan-out, transformation, and...
Hookdeck Transformations API
Manage transformations — sandboxed JavaScript executed against events to mutate headers, body, path, or query string before delivery. Also includes a sandboxed run endpoint for ...
Hookdeck Bookmarks API
Save bookmarked events for quick replay and one-click testing during development. Bookmarks let your team capture canonical event payloads and trigger them on demand into any de...
Hookdeck Issues API
Track issues that occur on events, requests, and backpressure, and manage the triggers (rules) that open and route issues to Slack, Email, Microsoft Teams, Discord, BetterUptime...
Hookdeck Metrics API
Query aggregated metrics for events, requests, and attempts — success counts, failure counts, response time, throughput, and SLA bands grouped by source, destination, or connect...
Hookdeck Integrations API
Configure platform integrations that adapt Hookdeck behavior for specific source platforms — including signature verification, header normalization, allowed event types, and pla...
Hookdeck Notifications API
Manage how your team is notified when issues occur — channel routing, mute windows, per-team subscriptions, and the templates rendered to Slack, Email, Microsoft Teams, and Disc...
Hookdeck Attempts API
An attempt is any request that Hookdeck makes on behalf of an event.
Hookdeck Bulk cancel events API
Bulk cancel operations allow you to cancel multiple pending events at once.
Hookdeck Bulk retry events API
Bulk retry operations allow you to retry many events at once. A bulk retry is first estimated, then created, then processed asynchronously.
Hookdeck Bulk retry ignored events API
Bulk retry ignored events allow you to retry many events that were previously ignored (for instance due to filter rules) at once.
Hookdeck Bulk retry requests API
Bulk retry requests allow you to re-ingest many previously received requests at once.
Hookdeck Issue Triggers API
Issue Triggers lets you setup rules that trigger issues when certain conditions are met.

Arazzo Workflows 14
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.
Multi-step API workflows described with the Arazzo specification.
Hookdeck Attach an Integration to a New Source
Create a source, create an authentication integration, then attach the integration to the source.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Hookdeck Rate Limits
RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

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.

Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
