What is Zavu?

Zavu acts as a consolidated API that addresses all your messaging requirements, enabling you to send and receive SMS, WhatsApp messages, emails, voice calls, Telegram messages, and more through a single integration point. This platform allows developers to simplify the messaging workflow, eliminating the difficulties associated with managing various messaging systems by consolidating numerous APIs, SDKs, authorization processes, webhook patterns, sender settings, template validations, and error tracking into one SDK, a uniform webhook structure, and a centralized dashboard. Built with AI agents in mind, Zavu facilitates their global communication capabilities across SMS, WhatsApp, email, and voice, while providing developers with access to fully functional SDKs in languages such as Node.js, Python, Ruby, Go, PHP, and Java. The system’s Smart Send and AI Routing features effectively determine the best messaging channel—whether SMS, WhatsApp, or email—based on the recipient's preferences, thus optimizing delivery through comprehensive platform-wide intelligence and automatically switching to alternative channels as needed. Throughout this process, the system ensures that context is preserved, duplicates are avoided, and expenses are carefully tracked during every stage of the fallback mechanism, guaranteeing efficiency and transparency for users. Furthermore, Zavu's all-encompassing strategy facilitates smooth integration with existing workflows, significantly improving the overall experience for users and developers alike.
