Enterprise CPaaS & APIs

Enterprise CPaaS: messaging that runs on your business events

Connect one API to your CRM, ERP, billing, or logistics systems and let real events trigger the message — a shipment that moved, a payment that came due, a login that needs verifying. Messangi consolidates SMS, WhatsApp, RCS, and email behind a single integration, with webhooks and events in both directions and delivery visibility your operations team can read without opening a ticket.

The problem isn't the API. It's everything around it.

Most enterprises running operations across the US and LATAM describe the same situation: messaging is spread across vendors and internal scripts, every new use case needs engineering, and nobody has one view of what was sent or delivered. Adding another single-channel API doesn’t fix that — it adds a fourth place to look. What changes the picture is one integration that covers every channel, plus a team in your time zone when a route misbehaves at 2 a.m.

What you integrate once

One API request to /v1/messages with WhatsApp and SMS fallback, fanning out to SMS, WhatsApp, RCS and email; a delivery log by channel and market; webhook events; consent checked before delivery

One multichannel API layer

Send and receive across SMS, WhatsApp, RCS, and email through one integration and one authentication model. Adding a channel later is a configuration change, not a project.

Webhooks and event-driven triggers

Subscribe to delivery states, inbound replies, and consent changes. Fire messages from business events instead of scheduled jobs, so what customers receive matches what actually happened.

Routing and delivery visibility

See how traffic is routed and where each message ends up, per channel and per market — with logs and callbacks your team can query, not a monthly summary.

Consent and compliance built into the send path

Consent Management checks opt-in state before delivery, and the consent and sender registration rules of each market are applied to your traffic — handled by our team during onboarding rather than left as a form for yours.

Operations without engineering in the loop

The same channels are available in the Communications Console, so business teams can run a campaign or edit a template without a release.

What onboarding actually looks like

The integration runs on REST for application traffic, with an SMPP gateway available for teams already sending over SMPP — both on the same platform, reporting to the same place. What sets the timeline is rarely the code: it’s WhatsApp verification and sender registration in each market, and our team handles that work alongside yours. You get an engineer from the first call rather than a documentation link, and a timeline for your specific markets rather than an average.

One API reference for every channel

SMS, WhatsApp, RCS, and email share one integration and one authentication model. The documentation covers REST, SMPP, and webhooks.
