Messaging infrastructure WhatsApp Business Platform

Messaging infrastructure for many businesses at once.

A multi-tenant platform being built on Meta's WhatsApp Business Platform, so that several businesses can connect their own numbers and run their messaging through one system.

Integrating WhatsApp properly - webhooks, message types, templates, operator inboxes - is substantial work. Doing it once per business does not scale, and each business ends up maintaining its own fragile integration.

We are building the integration once as a platform. Each business is a tenant with its own WhatsApp connection, and inbound webhooks are routed to the right tenant so their conversations, operators and automation stay separate.

The platform builds on integration work already running in PaalTech's own systems - Cloud API messaging with interactive buttons and lists, webhook verification and handling, and an operator inbox where staff can take over a conversation from automation - and extends it to many tenants.
