How it works
1
User Dials
Customer dials *365# on any Mozambican network
*365#→
2
Provider Sends
Telco sends SOAP/XML/JSON to OLA
SOAP/XML/JSON→
3
OLA Normalizes
Gateway converts to clean JSON
{ "msisdn": "258..." }→
4
Your Backend
Process & return menu response
{ "output": [...] }Write USSD backends in any language
All you need is an HTTP endpoint that accepts JSON. Build in the language you know best.
- ✓ Node.js / Express
- ✓ Python / Flask / Django

// Node.js Example
app.post('/ussd', (req, res) => {
const { msisdn, input } = req.body;
let menu;
if (!input) {
menu = [
"Welcome to MyBank",
"",
"1. Check Balance",
"2. Transfer Money"
];
} else if (input === "1") {
const balance = getBalance(msisdn);
menu = [`Balance: ${balance} MZN`];
}
res.json({
output: menu,
end_session: false
});
