How to integrate M-Pesa and e-Mola into your site or app

Most Mozambicans pay by phone. If your site or app doesn't accept M-Pesa and e-Mola, you're losing sales - the customer wants to pay on the spot, without a card and without leaving home.

Integrating these methods is no longer a luxury: it's what separates an online business that converts from one that watches the cart get abandoned.

In the most common model (C2B - customer to business), the customer enters their number, receives a payment request on their phone and confirms with their PIN. Your system then receives a confirmation and automatically releases the product, invoice or service.

The critical part is automatic confirmation: the payment must be validated by the server (via the operator's callback/webhook), never just by the customer's word. This is what prevents fraud and manual work.

M-Pesa (Vodacom) and e-Mola (Movitel) are the most used mobile wallets. Many businesses want to accept both so as not to exclude customers on either network. You can also integrate bank transfers and cards to complete the options.

Each operator has its own API and approval process - the technical integration is similar, but the details (credentials, test environment, limits) differ.

On the business side: a business account with the operator (M-Pesa Business / e-Mola Business) and, usually, the NUIT for invoicing. On the technical side: access to the operator's API and a system ready to receive and validate confirmations.

Then comes receipt issuing, logging each transaction, and reconciliation - knowing, at any moment, which payments came in and which orders they match.

Never trust only the "paid" message shown to the customer. Always validate on the server, store each transaction's identifier, and handle duplicate and timeout cases. A well-built integration is invisible to the customer and error-proof for the business.
