About

Webhook.site is a tool for testing, transforming, and automating web requests, webhooks, and emails through unique URLs and email addresses that show everything sent to them instantly. With Webhook.site, users receive a unique, random URL that can be used to test and debug webhooks and HTTP requests, inspect payloads, headers, query strings, and request details in real time, and replay items later when troubleshooting or reprocessing failed flows. It helps remove the frustration of building software and automations that communicate through webhook or email by making requests visible, persistent, and easier to understand. Webhook.site also supports Custom Actions, a graphical workflow editor that runs when a URL receives a request or email, allowing users to connect incompatible APIs, convert an HTTP request to an email or vice versa, transform, validate, and process requests, and build workflows that would otherwise require development work.

About

Zavu is one API for all your messages, built to send and receive SMS, WhatsApp, Email, Voice, Telegram, and more from a single integration. It helps developers ship messaging instead of maintaining messaging infrastructure, replacing separate APIs, SDKs, auth models, webhook formats, sender setup, template approvals, and error handling with one SDK, one webhook format, and one dashboard. Zavu is also built for AI agents from day one: agents can send SMS, WhatsApp, Email, and Voice globally, while developers can use production-ready SDKs across languages such as Node.js, Python, Ruby, Go, PHP, and Java. Its Smart Send and AI Routing features pick SMS, WhatsApp, or Email per contact, choose the best or cheapest delivery path using platform-wide delivery intelligence, and fall back automatically when a channel fails. Context is preserved, delivery is deduplicated, and cost is tracked end-to-end across the fallback chain.
