Simulate Fiat Payment

The simulate endpoint lets you trigger a test fiat payment confirmation in the test environment without going through a real bank transfer. This is useful for end-to-end testing of your integration — confirming webhooks fire, order statuses update correctly, and your app handles payment success as expected.

This endpoint only works with test API keys (sk_test_...). Calling it with a live key will have no effect on live transactions.

---

How It Works

1. You create a payment request using POST /v1/transactions (with your test secret key)

2. The customer receives bank account details to pay into

3. Instead of waiting for a real bank transfer, you call POST /v1/fiat-transfer/simulate with the transaction reference

4. IvoryPay marks the transaction as SUCCESS and fires your configured webhook

Full Test Flow

Step 1 — Create a payment request

POST /v1/transactions
Authorization: sk_test_xxxxxxxxxxxxxxxxxxxxxxxx
Content-Type: application/json

{
  "amount": 5000,
  "email": "[e-mail]",
  "firstName": "John",
  "lastName": "Doe",
  "type": "FIAT",
  "baseFiat": "NGN",
  "reference": "a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c"
}

Response — payment details:

{
  "status": true,
  "message": "Transaction initiated successfully",
  "data": {
    "reference": "a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c",
    "status": "PENDING",
    "collectionDetails": {
      "bankName": "Test Bank",
      "accountNumber": "0123456789",
      "accountName": "IvoryPay Test",
      "amount": 5000
    }
  }
}

Step 2 — Simulate the payment

POST /v1/fiat-transfer/simulate
Authorization: sk_test_xxxxxxxxxxxxxxxxxxxxxxxx
Content-Type: application/json

{
  "reference": "a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c"
}

Step 3 — Verify the transaction status

GET /v1/business/transactions/a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c/verify
Authorization: sk_test_xxxxxxxxxxxxxxxxxxxxxxxx

{
  "status": true,
  "message": "Transaction details retrieved successfully",
  "data": {
    "reference": "a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c",
    "status": "SUCCESS",
    ...
  }
}

Code Samples

Node.js

const axios = require('axios');

const API_KEY = 'sk_test_xxxxxxxxxxxxxxxxxxxxxxxx';
const BASE_URL = 'https://api.ivorypay.io/api';
const reference = 'a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c';

async function runTestFlow() {
  // Step 1: Create payment request
  const { data: txn } = await axios.post(

    {
      amount: 5000,
      email: '[e-mail]',
      firstName: 'John',
      lastName: 'Doe',
      type: 'FIAT',
      baseFiat: 'NGN',
      reference,
    },
    { headers: { Authorization: API_KEY } },
  );

  console.log('Transaction created:', txn.data.status);

  // Step 2: Simulate payment
  await axios.post(
    `${BASE_URL}/v1/fiat-transfer/simulate`,
    { reference },
    { headers: { Authorization: API_KEY } },
  );

  console.log('Payment simulated');

  // Step 3: Verify
  const { data: verified } = await axios.get(
    `${BASE_URL}/v1/business/transactions/${reference}/verify`,
    { headers: { Authorization: API_KEY } },
  );

  console.log('Transaction status:', verified.data.status); // SUCCESS
}

runTestFlow();

PHP

<?php

$apiKey    = 'sk_test_xxxxxxxxxxxxxxxxxxxxxxxx';
$baseUrl   = 'https://api.ivorypay.io/api';
$reference = 'a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c';

Webhook Testing

When you call the simulate endpoint, IvoryPay will fire a fiatCollection.success webhook event to your configured webhook URL (if set). This is the same payload you will receive in production.

Example webhook payload:

{
  "event": "fiatCollection.success",
  "data": {
    "reference": "a3f1c2d4-58e7-4b19-9c3a-1d2e3f4a5b6c",
    "status": "SUCCESS",
    "amount": 5000,
    "currency": "NGN",
    "customer": {
      "email": "[e-mail]",
      "firstName": "John",
      "lastName": "Doe"
    }
  }
}

See Webhooks for how to verify the signature and handle events.

Important Notes

Rule	Detail
Test only	Only works with sk_test_... keys — no effect on live transactions
One-time	Simulating the same reference twice has no effect after the first success
Reference must exist	The transaction must have been created first via POST /v1/transactions
Webhook fires	Your webhook URL will receive the fiatCollection.success event
