Sendexa Now Supports WhatsApp Business API

Send templated messages, run broadcast campaigns, build chatbot flows, and manage two-way WhatsApp conversations — all from one dashboard, powered by Sendexa.

WhatsApp is where people in Africa actually are. Over 97% of smartphone users in Ghana have WhatsApp installed. It is not just a messaging app — it is the primary communication channel for businesses and customers across the continent. We built Sendexa to meet businesses where their customers are, and that means WhatsApp.

Today, Sendexa adds full WhatsApp Business API support. This is not a third-party integration bolted on — it is a first-class product with its own dashboard, its own API, and its own developer tooling, built to the same standard as everything else we ship.

What You Can Do

Template Messaging

WhatsApp requires pre-approved message templates for business-initiated conversations. The Sendexa dashboard gives you a full template management interface — create templates, submit them for Meta approval, and track their status. Once approved, templates are ready to use immediately across broadcasts and API calls.

Broadcasts and Campaigns

Send WhatsApp messages to your entire audience or a specific segment in one go. Schedule broadcasts in advance, monitor campaign delivery in real time, and review full reports after the fact. Every broadcast is scoped to your approved templates, so you stay compliant with WhatsApp's policies automatically.

Chatbots and Automated Flows

Build automated conversation flows that respond to incoming WhatsApp messages without any manual intervention. Set up triggers based on keywords or message patterns, define the flow logic, and let the chatbot handle the conversation. Logs for every interaction are available in the dashboard, so you can see exactly how your flows are performing and debug anything that is not working as expected.

Messaging Inbox

Two-way messaging is fully supported. When a customer replies to a WhatsApp message — whether from a campaign or a chatbot — you can view and respond from the Sendexa inbox. Message history is stored and searchable. This is not just a broadcast tool; it is a real conversation channel.

Audience Management

Manage your WhatsApp contacts and groups directly in the platform. Opt-outs are tracked automatically — when a user opts out, they are removed from future broadcasts without any manual work on your end. This keeps you compliant and keeps your audience lists clean.

Analytics

The analytics section breaks down performance across three dimensions: messages (delivery rates, read rates), campaigns (per-broadcast performance), and audience (growth, opt-outs, engagement trends). All data is scoped to your business and updated in real time.

Phone Number Management

Connect your WhatsApp Business phone numbers through the dashboard. You can manage multiple numbers, view their connection status, and add new ones as your business grows.

Built for Developers Too

Everything in the dashboard is also available via API. The developer section gives you API key management and webhook configuration. Webhooks fire on incoming messages, delivery status updates, and campaign events — so you can integrate WhatsApp delivery data into your own systems without polling.

Integrated with the Rest of Sendexa

The WhatsApp dashboard is a full Sendexa product — which means it plugs directly into the platform you already use. It uses Central Auth for SSO, so your existing Sendexa login works immediately. Billing runs through Sendexa Wallet, so your WhatsApp message costs sit alongside your SMS and OTP costs in one place. And it supports multi-business — if you manage multiple businesses on Sendexa, each has its own independent WhatsApp setup.

Getting Started

To connect your WhatsApp Business account, log into your Sendexa dashboard and navigate to the WhatsApp section. The onboarding flow will walk you through connecting your Meta Business account and registering your phone number. Once connected, your number is live and ready for templates, broadcasts, and API calls.

WhatsApp is where your customers are. Now Sendexa is there too.
