Webhooks

A technical guide to testing webhooks on localhost in 2026 - provider CLIs like stripe listen and gh webhook forward, HTTPS tunnels, relay services like Hookdeck and Svix, plus the raw-body signature trap that breaks most handlers.

A technical deep-dive into webhooks: what they are, how they work, how to build a secure receiver with HMAC signature validation, handle retries idempotently, and test locally during development.

Complete guide to self-hosting Node-RED, the powerful flow-based programming tool for IoT and automation. Install locally and access from anywhere using Pinggy tunnels.

Understand the key differences between webhooks and APIs, their use cases, and when to choose each for your application. Complete guide with examples and best practices.

Receive GitHub, Stripe, Slack and Shopify webhooks on localhost: open a Pinggy tunnel, verify the HMAC signature on the raw body, replay deliveries in the Web Debugger, and know when a provider CLI fits better.
