The Top-up API lets your own system add credits to your Yoola SMS account with MTN or Airtel Mobile Money, with no login. It is switched on for approved accounts only. You need a Yoola SMS account first (create one free).

What you get

Start an MTN or Airtel Mobile Money payment from your own app or website.
Credits are added to your account automatically once the payment is approved.
Check any payment's status at any time.
Safe to retry: the same reference never charges twice.

Good to know

Uganda (UGX) accounts, MTN and Airtel.
The payer pays the amount plus a 0.5% mobile money fee.
