Introduction
Everything you need to build high-scale applications with Ziett infrastructure.
Ziett is a developer-first Communications Platform as a Service (CPaaS) built for teams that need to send messages at scale — reliably, efficiently, and across multiple channels. Whether you're triggering a single transactional OTP or orchestrating a multi-channel campaign to hundreds of thousands of recipients, Ziett gives you a single, unified API to do it.
What You Can Build
- Transactional Messaging — Send real-time alerts, OTPs, delivery notifications, and system events via SMS or WhatsApp triggered directly from your application.
- Bulk Campaigns — Upload contact lists and dispatch high-volume marketing or operational campaigns asynchronously, with full delivery tracking.
- Omnichannel Fallback — Define routing logic that attempts delivery through your preferred channel (e.g., Push Notification) and automatically falls back to WhatsApp or SMS if the first attempt fails.
- Template-Based WhatsApp — Send approved Meta HSM (Highly Structured Message) templates for utility, marketing, and authentication use cases — with variable injection handled server-side.
Supported Channels
| Channel | Status | Notes |
|---|---|---|
| SMS | Available | Full support for transactional and bulk messaging |
| WhatsApp (HSM) | In Integration | Template-based messaging via Meta Cloud API |

Get Started
- Get your API Key from the Ziett Dashboard under Organization → API Keys.
- Read the Authentication guide to learn how to include your key in every request and how to keep it secure.
- Make your first call — Send a transactional message with a destination number and message body.
That's all it takes to get your first message out the door. The rest of this documentation covers everything you need to go from a working prototype to a production-grade integration.
