Configure Stripe to send `checkout.session.completed` and `invoice.payment_succeeded` events to your unique Hookly URL. Inspect payloads, replay failed deliveries, and verify signatures — all from your browser. Includes a ready-to-copy Node.js handler using `stripe.webhooks.constructEvent()`.

Connect your GitHub repository to Hookly in under two minutes. Trigger real `push`, `pull_request.opened`, and `workflow_run` events from your local machine. Learn how to parse the `X-Hub-Signature-256` header and build a reliable event router in Python using Flask.

Use Hookly as the request URL for your Slack app. Capture incoming slash command payloads, test different response formats, and iterate on your logic without deploying. The guide walks through setting up a `/remind` command that posts scheduled messages back to Slack via the Web API.

Subscribe to `PAYMENT.SALE.COMPLETED` and `BILLING.SUBSCRIPTION.ACTIVATED` events. Verify the `paypal-auth-algo` and `paypal-cert-url` headers, then route events to your order management system.

Forward `pipeline_success` and `pipeline_failure` events from GitLab to Hookly. Build a dashboard that aggregates pass rates across projects and sends daily summaries to your team channel.

Point your Discord application's webhook URL at Hookly. Capture `MESSAGE_CREATE` and `INTERACTION_CREATE` payloads, then build a command parser in Go that responds to `/roll` and `/quote` commands.

Create a `/api/webhooks/stripe` route in Next.js that validates signatures, idempotently processes events, and returns `200 OK`. Use Hookly to replay events and test edge cases like duplicate deliveries and out-of-order arrivals.

Write reusable Express middleware that checks `X-Signature-256` headers against a shared secret. The guide covers rate limiting, payload logging, and graceful handling of malformed requests — tested live through Hookly.

Set up a Django view with `csrf_exempt` that deserializes webhook JSON, validates HMAC signatures, and queues heavy tasks via Celery. Includes migration scripts and a test suite driven by Hookly replayed events.

Capture `subscription.created`, `subscription.canceled`, and `transaction.completed` events from Paddle. Verify the `X-Paddle-Signature` header and sync subscription states with your PostgreSQL database.

Configure Jenkins to POST build status changes to your Hookly endpoint. Parse the `result` field (`SUCCESS`, `FAILURE`, `UNSTABLE`) and trigger automated Slack alerts or email digests based on failure patterns.

Set Hookly as your Telegram bot's webhook URL using `setWebhook`. Capture `message`, `callback_query`, and `inline_query` updates. Build an inline keyboard menu in TypeScript and handle button callbacks with type-safe payload parsing.
