The official channel to reach 30M+ WhatsApp users in Malaysia. Send OTP, marketing, utility and service messages — at scale, programmatically, via REST API.
The WhatsApp Business API (WABA) is a powerful tool that allows businesses to communicate with their customers on WhatsApp — one of the world's most popular messaging platforms. It enables you to send and receive messages, notifications, and multimedia content, offering a direct and convenient way to engage with your audience at scale.
Every WhatsApp Business API message falls into one of four categories. Each serves a distinct business purpose with its own template approval requirements.
Go beyond plain text — engage customers with interactive, visual, and structured messages.
Interactive menus and quick-reply buttons for guided conversation flows — no typing required.
Display product pages, shopping carts, and multi-product messages for e-commerce businesses.
Embed URLs or phone numbers directly in messages — drive clicks and calls from WhatsApp.
Send product images, banners, video guides, and visual content with caption text.
Attach invoices, receipts, manuals, and catalogues as PDF files directly in the chat.
Send GPS coordinates, branch maps, and delivery tracking links within WhatsApp.
Generate and send QR codes or barcodes for tickets, loyalty cards, and vouchers.
Pre-approved message templates for proactive outreach — marketing, OTP, alerts, reminders.
Automated, context-aware replies powered by AI — with seamless agent handover.
