Unified API for WhatsApp, SMS & USSD
Everything you need to communicate with your customers at scale
Official Meta Business API (recommended) for green-tick verified messaging, or QR connection for quick start. Rich messages, images, PDFs, and campaigns.
Reliable SMS delivery to all Kenyan networks. Perfect for OTPs, alerts, and marketing campaigns. Volume tiers, VAT inclusive.
Launch your own USSD service without building telecom infrastructure. Interactive menus, real-time requests, and API integration.
We recommend the Official Meta API for reliability and compliance. The QR connection is available for quick testing but carries risk.
Billed separately from SMS, at the rate for the template category you send. Replies within an open conversation are free.
| Message type | Rate (KES/message) | Notes |
|---|---|---|
| Marketing | KES 6.00 / msg | Promotions, offers, announcements |
| Utility | KES 1.00 / msg | Order updates, receipts, alerts |
| Authentication | KES 1.00 / msg | OTPs, login codes, verification |
Requires WhatsApp Business number and pre-approved templates. We handle the setup with you.
Connect your existing WhatsApp number by scanning a QR code. Fast setup, no verification.
Our recommendation: Choose the Official Meta API for compliance, green-tick verification, and zero risk of number restrictions. Use QR only for testing or short-term campaigns.
The amount you pay determines your rate. From KES 0.40 per credit at the highest band. All prices include VAT. No monthly fees.
1 credit = 1 SMS (160 chars) to any network. All prices are VAT inclusive.
| Amount you pay (KES) | Price per credit (VAT incl.) | Example: you get |
|---|---|---|
| 1 – 1,000 | KES 0.80 | Pay KES 800 → 1,000 credits |
| 1,001 – 5,000 | KES 0.70 | Pay KES 3,500 → 5,000 credits |
| 5,001 – 20,000 | KES 0.60 | Pay KES 12,000 → 20,000 credits |
