Unified Messaging API for SMS, WhatsApp & RCS

Write Once. Deliver Everywhere with One Omnichannel Messaging API

Deliver your brand message with a single Unified Messaging API that orchestrates SMS, WhatsApp and RCS using intelligent routing, costbased optimisation and automatic fallback.

SMS, WhatsApp & RCS Messaging API

Multi‑Channel Messaging Is Broken

Replace multiple channelspecific integrations with one omnichannel messaging layer. Send messages via a single endpoint,
use a unified webhook for all delivery events, and let the smart delivery engine pick the best channel based on cost,
performance and historical delivery data.

Multi-Channel Communication API

  • Different APIs per channel

  • Different payload formats

  • Separate webhooks

  • Manual fallback logic

  • Cost unpredictability

  • Fragmented delivery tracking

One API. Every Channel. Zero Complexity.

Unify SMS, WhatsApp, and RCS under one intelligent orchestration engine with a single endpoint, smart routing, automatic fallback, unified tracking, and a single webhook.

One API, Every Channel

Single endpoint for SMS, WhatsApp and RCS with a unified payload model.

Smart Routing & Fallback

Route by cost or speed and automatically fail over between channels to prevent message drops.

Unified Webhook & Tracking

One webhook and one message ID for statuses, failures and timestamps across all channels.

Smart Delivery Engine

Intelligent routing and failover to ensure your messages always reach their destination, optimizing for cost and speed.

Delivery Modes

  • Order: deliver in the exact sequence you define.
  • Budget: automatically select the lowest‑cost channel.
  • Quick: choose the fastest channel using historical performance.

Automatic Fallback

Never miss a delivery. If a message fails, the engine retries on the next channel:

  • WhatsApp → SMS
  • RCS → WhatsApp
  • SMS → next preferred channel

Unified Tracking

  • Single message ID
  • Channel‑level status updates
  • Failure reasons
  • Timestamp lifecycle
  • Single webhook
