Mobile money dominates commerce in Zambia. Over 91% of Zambian SME transactions tracked by Filika in Q1 2026 involved a mobile payment — and MTN MoMo is the largest network. If your online store does not accept MoMo, you are excluding the majority of your buyers before they even see your prices.
Here is how to integrate it properly.
Understanding MTN MoMo in Zambia
MTN Mobile Money Zambia operates on the MTN MoMo API, a REST API that lets businesses initiate payment requests directly to a customer’s phone. The customer receives a USSD prompt, enters their PIN, and the payment is confirmed within seconds — no bank account required.
Businesses must be registered as MTN MoMo merchants. This requires a PACRA certificate, your business bank account details, and a valid ID for the account signatory. Processing time is typically 5–10 business days.
Three Integration Routes
Option 1: MTN MoMo API (Direct)
This is the most powerful option. MTN Zambia provides sandbox and production API access. You authenticate with OAuth 2.0 tokens, make a POST /collection/v1_0/requesttopay call with the customer’s phone number and amount, and poll for status or receive a webhook callback.
Best for: Developers building custom platforms who want full control.
Costs: No platform fee. MTN charges a merchant rate negotiated at sign-up, typically 0.5%–1.5% per transaction.
Option 2: DPO Group (Aggregator)
DPO Group is a payment gateway operating across Africa that supports MTN MoMo, Airtel Money, Visa, and Mastercard in a single integration. You send a payment request to DPO’s API, they handle the MoMo handshake, and you receive a callback.
Best for: Businesses that want multi-channel payments (cards + mobile money) without integrating each separately.
Costs: DPO charges 2.5%–3.5% per transaction depending on volume. Simpler to integrate than direct MoMo.
Option 3: Filika Ecommerce Platform
If you are launching a new online store in Zambia, the Filika platform ships with both MTN MoMo and DPO Group integrations already built and tested. You activate them from your merchant dashboard — no API work required.
Best for: SMEs who want to sell online quickly without a development team.
Costs: Platform subscription starts at K500/month plus 1.5% transaction fee on the Starter plan.
Common Integration Mistakes
Wrong phone number format. The MTN MoMo API expects Zambian numbers in international format without the plus sign: 260971234567, not 0971234567 or +260971234567.
Missing error handling for timeouts. Customers sometimes dismiss the USSD prompt or lose signal mid-transaction. Your store must handle PENDING status gracefully and not mark an order as paid until you receive SUCCESSFUL.
Not testing on real devices. The MTN MoMo sandbox does not accurately simulate network timeouts or user cancellations. Test your integration on a live merchant account before going to production.
Next Steps
- Register as an MTN MoMo merchant through the MTN Business portal in Lusaka.
- Request sandbox credentials from MTN’s API team.
- Integrate using one of the three routes above based on your technical capacity.
