Choose the lane that matches the work.
The blog is organized around practical webhook jobs: shipping an integration, understanding a provider, or designing the recovery model behind reliable delivery.
Build the workflow
Step-by-step paths for receiving webhooks, testing locally, verifying signatures, routing traffic, and recovering failed deliveries.
IntegrationsConnect providers
Provider notes for Stripe, GitHub, Shopify, and internal webhook producers, with payload, signature, retry, and routing details.
EngineeringDesign reliable delivery
Architecture notes about attempts, retries, replay, throughput control, observability, and operator-safe webhook infrastructure.
Blog essays
Opinionated notes for reliability decisions.
These posts are for architecture choices, failure analysis, provider mistakes, and the operational tradeoffs behind webhook gateways.
Why most webhook systems lose events
Where events disappear when receipt, processing, retries, and replay live in one fragile endpoint.
Lessons learned building a webhook gateway
Product and engineering notes from separating requests, routed events, attempts, retries, and replay.
Hookdeck vs custom webhook processing
How to decide between custom receiver logic and a dedicated webhook gateway layer.
Stripe webhooks at scale
Operate Stripe billing events with signatures, idempotency, replay, and ordering-aware recovery.
Common GitHub webhook mistakes
Avoid payload, header, signature, branch filter, retry, and replay mistakes in GitHub automation.

Start with the webhook problem you need to solve.
Use these guides when you need a practical path through testing, debugging, endpoint setup, and delivery behavior before going deeper into API reference details.
Webhooks
A practical overview of webhook delivery, failure modes, retries, duplicates, and where a webhook gateway fits.
WorkflowWebhook testing
Build repeatable webhook tests with realistic payloads, local endpoints, provider retries, and delivery inspection.
OperationsWebhook debugging
Debug webhook incidents from request receipt to destination attempts, response status, retry state, and replay decisions.
APIWebhook endpoints
Create provider-facing source URLs and route accepted webhook traffic through FastHook destinations and connections.
Provider playbooks
Stripe and GitHub webhook paths.
Provider pages focus on the details that usually cause production surprises: signatures, payload shape, event type filtering, retries, and replay-safe receivers.
Stripe webhooks
Receive billing events, verify signatures, and keep checkout, invoice, and subscription handlers replay-safe.
Stripe webhook example
Use a concrete Stripe-style payload and endpoint example when documenting or testing a billing integration.
GitHub webhooks
Route repository, pull request, issue, workflow, and deployment events without brittle direct delivery.
GitHub webhook payload examples
Compare GitHub push and pull request payloads, headers, delivery IDs, and fields worth logging.
GitHub push event payload
Use ref, before, after, commits, and head_commit.message safely in branch automation.
GitHub pull request webhook
Route PR actions, base branches, head SHAs, and preview workflows without mixing them into push handling.
GitHub webhook headers
Understand event, delivery, hook, content type, and signature headers before debugging GitHub deliveries.
GitHub webhook signature validation
Validate X-Hub-Signature-256 with the raw request body, HMAC-SHA256, and timing-safe comparison.
Shopify webhooks
Handle Shopify topics, HMAC signatures, duplicate delivery IDs, fast 2xx responses, and retries.
Twilio webhooks
Validate X-Twilio-Signature and route status callbacks with payload history and replay controls.
