WhatsApp Business API Provider
Darwinbark builds WhatsApp Business API platforms for businesses that have outgrown a single shared WhatsApp number - multiple agents working one inbox, automated broadcast campaigns, and real visibility into what's actually being delivered and read.
Why the Official API Matters
We build exclusively on the official, Meta-verified WhatsApp Business Cloud API - not an unofficial or session-based integration that risks the number being banned the moment message volume picks up. Every business we build for connects their own WhatsApp Business Account (WABA) through the official channel.
Multi-Agent Inbox
A shared WhatsApp number with multiple support agents needs conversation assignment and a real team inbox - otherwise agents step on each other's replies or lose track of who's handling what. We build that as core infrastructure, not an add-on.
Broadcast Campaigns Without Getting Rate-Limited
Outbound campaigns run through a queue rather than firing all at once, respecting Meta's per-account messaging rate limits automatically. Template messages - the pre-approved formats required for business-initiated conversations - go through Meta's approval flow before they're available to send, so a campaign never gets blocked by a compliance issue discovered after the fact.
Multi-Tenant Option
For businesses that want to offer WhatsApp automation to their own customers as a product, we also build multi-tenant platforms - one system serving many independently-branded businesses, each with their own connected WABA. See the full build: WhatsApp Business SaaS Platform.
