Mom Factura Testing & QA

Test payment integrations without processing real transactions.

Base URL: https://api.momenu.online

Enable QA Mode

Add header x-env-qa: true to use the test environment. Works from any origin.

For local development, also add x-dev-mode: true (localhost/127.0.0.1 only).

Content-Type: application/json
x-api-key: YOUR_API_KEY
x-env-qa: true
x-dev-mode: true

Simulate Payment Results

The simulateResult field in the MCX endpoint body triggers specific scenarios. Only active when x-env-qa: true.

| Value | Behavior | |-------|----------| | success | Payment succeeds, returns transactionId and invoiceUrl | | insufficient_balance | Fails: client has no balance | | timeout | Fails: no response from provider | | rejected | Fails: payment explicitly rejected | | invalid_number | Fails: phone not registered |

Internal test phone mapping (automatic, no action needed):

• success → 244900000000
• insufficient_balance → 244900000001
• timeout → 244900000002
• rejected → 244900000003
• invalid_number → 244999999999

Test Examples

Successful MCX Payment

curl -X POST https://api.momenu.online/api/payment/mcx \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "x-env-qa: true" \
  -d '{"paymentInfo":{"amount":1000,"phoneNumber":"244923456789"},"simulateResult":"success"}'

Insufficient Balance

curl -X POST https://api.momenu.online/api/payment/mcx \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "x-env-qa: true" \
  -d '{"paymentInfo":{"amount":5000,"phoneNumber":"244923456789"},"simulateResult":"insufficient_balance"}'

Amount Validation Error

curl -X POST https://api.momenu.online/api/payment/mcx \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "x-env-qa: true" \
  -d '{"paymentInfo":{"amount":2500,"phoneNumber":"244923456789"},"products":[{"id":"1","productName":"P","productPrice":3000,"productQuantity":1}],"simulateResult":"success"}'

Returns: { "success": false, "code": "AMOUNT_MISMATCH" }

Reference in QA

curl -X POST https://api.momenu.online/api/payment/reference \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "x-env-qa: true" \
  -d '{"paymentInfo":{"amount":10000}}'

Test Helpers

JavaScript

const API = "https://api.momenu.online";
const headers = {
  "Content-Type": "application/json",
  "x-api-key": "YOUR_API_KEY",
  "x-env-qa": "true"
};

async function testMCX(simulateResult = "success") {
  const res = await fetch(`${API}/api/payment/mcx`, {
    method: "POST", headers,
    body: JSON.stringify({
      paymentInfo: { amount: 1000, phoneNumber: "244923456789" },
      simulateResult
    })
  });
  return res.json();
}

// Run all scenarios
for (const s of ["success","insufficient_balance","timeout","rejected","invalid_number"]) {
  testMCX(s).then(r => console.log(s, r.success ? "PASS" : "FAIL", r));
}

Python

import requests

API = "https://api.momenu.online"
headers = {"Content-Type": "application/json", "x-api-key": "YOUR_API_KEY", "x-env-qa": "true"}

def test_mcx(simulate="success"):
    r = requests.post(f"{API}/api/payment/mcx", json={
        "paymentInfo": {"amount": 1000, "phoneNumber": "244923456789"},
        "simulateResult": simulate
    }, headers=headers)
    return r.json()

for s in ["success", "insufficient_balance", "timeout", "rejected", "invalid_number"]:
    result = test_mcx(s)
    print(f"{s}: {'PASS' if result.get('success') else 'FAIL'} - {result}")

Common Issues

| Error | Cause | Fix | |-------|-------|-----| | DOMAIN_NOT_ALLOWED | Origin not registered | Add x-dev-mode: true (localhost) or register domain | | MISSING_API_KEY | Header missing | Check header is x-api-key (lowercase, hyphens) | | AMOUNT_MISMATCH | amount != products total | Verify SUM(price*qty) == amount, or send only one | | MISSING_PHONE | No phone for MCX | Add paymentInfo.phoneNumber (not needed for Reference) | | simulateResult ignored | Not in QA mode | Add header x-env-qa: true | | simulateResult ignored | Wrong endpoint | Only works on MCX, not Reference |

Pre-Production Checklist

1. Remove x-env-qa: true header
2. Remove x-dev-mode: true header
3. Remove simulateResult from request bodies
4. Register production domain in merchant panel
5. Store API key in environment variables (never hardcode)
6. Implement error handling for all error codes
7. Implement webhook endpoint to receive payment confirmations
8. Implement status endpoint fallback for Reference
9. Verify amount validation with products
10. Test with real phone numbers
