WhatsApp Business API — official integration without the BSP markup
Direct Meta WhatsApp Business Cloud API integration — templated messages, two-way conversations, and Stripe-grade reliability.
Most companies access WhatsApp's API through a Business Solution Provider (BSP) like Twilio, MessageBird, or 360dialog. The trade-off is convenience for per-message margin — and at scale, the margin gets painful. We build directly on Meta's WhatsApp Business Cloud API: same official surface, no markup, full control over templates, webhooks, and conversation routing. For some teams that's the right answer. For others — especially smaller volumes or teams that want a managed dashboard — a BSP is genuinely the better choice. We'll tell you which, then build whichever you pick. The work itself includes template approval (the part where most projects stall), opt-in flows that pass Meta review, conversation routing into your CRM or support tool, two-way messaging with operator handover, rich-media handling (PDFs, images, location pins), and full audit logs for compliance. If you're running paid marketing into WhatsApp, we also wire conversion tracking back into Meta Ads and your analytics stack.
About this service
Direct API or BSP?
Both are legitimate — picking the wrong one costs real money
Direct integration with Meta's WhatsApp Business Cloud API gets you the lowest per-conversation cost and full control over the message pipeline. The trade-off is that you (or we) own everything: template submission, webhook reliability, opt-in compliance, deliverability, the lot.
A BSP (Twilio, MessageBird, 360dialog, Vonage) hides the operational complexity behind a managed surface and a dashboard. The trade-off is per-message margin — usually 0.5x–2x Meta's cost — which compounds painfully past tens of thousands of conversations a month. We'll model both costs against your projected volume and pick the one that wins for you.
Templates and opt-in
The part most projects stall on
WhatsApp Business has strict rules on what you can send outside of an active 24-hour conversation window: only pre-approved template messages, only to users who explicitly opted in, only in categories Meta has approved for your business.
We handle the template submission process (utility, marketing, authentication categories), build the opt-in capture flows that pass Meta review, and structure your messaging program so you don't get throttled or shut off. We've taken multiple programs from zero to approved-template-live in under three weeks.
Two-way conversations and operator handover
WhatsApp is a support channel, not a broadcast channel
The biggest mistake we see is treating WhatsApp like SMS — fire-and-forget. The reason WhatsApp works as a channel is because the user replies, and now you're in a 24-hour service window where you can have a real conversation. That conversation needs to route somewhere: a CRM, a support tool, an AI agent, or a live operator.
We build the routing layer: incoming messages tagged and routed to the right team, operator handover with conversation history, escalation rules, SLA timers, and a clean handoff between bot and human when the bot reaches the edge of its competence.
