How to Easily Integrate Data, Airtime, and Bill Payment APIs Into Your App

In today’s fast-growing digital economy, customers expect speed, convenience, and automation. From buying data and airtime to paying electricity or TV bills, users want everything done instantly within a few taps.

For fintech founders, VTU startups, and e-commerce owners, offering these services inside your app or website can dramatically increase engagement and revenue. But many developers struggle with complex integrations, unstable APIs, and failed transactions.

That’s where Inlomax API comes in — a powerful, developer-friendly API that lets you easily connect data, airtime, and bill payment services to your platform in just a few lines of code.

In this guide, you’ll learn exactly how to integrate it smoothly and go live fast.

Why You Need Data, Airtime, and Bill Payment APIs

Whether you’re building a fintech app, reseller platform, or e-commerce website, APIs (Application Programming Interfaces) act as the bridge between your app and service providers.

They enable your system to communicate with telecom networks, utility companies, and payment processors — automating tasks like:

Buying mobile data and airtime instantly
Paying electricity, TV, and internet bills
Selling recharge and subscription services directly from your app
Managing and monitoring transactions in real time

With the right API integration, you can offer users more value, increase retention, and even earn commissions on every transaction — all while keeping your operations automated.

Common Challenges Developers Face During API Integration

Before showing you the easy path, let’s identify why most fintech startups and developers struggle with API integration:

Poor documentation or missing examples
Unstable endpoints that lead to failed transactions
Managing multiple APIs for different services
Long approval or testing processes
Downtime and unreliable transaction monitoring

These challenges waste time and money, and they frustrate your users.

That’s why Inlomax API was built — to simplify and streamline all of this.

Step-by-Step: How to Integrate Inlomax API Into Your App

Integration takes just a few steps. Let’s walk through it.

Step 1: Get Your API Key

Visit Inlomax.com
Create an account or log in
Navigate to your dashboard and generate your API Key

This key will be used to authenticate every API request.

Step 2: Choose the Service Endpoint

Inlomax offers multiple endpoints, including:

/api/airtime – For airtime purchase
/api/data – For mobile data
/api/subcable – For cable TV subscription
/api/payelectric – For bill payment

Step 3: Send API Requests

Example (PHP):

<?php
$apiKey = "YOUR_API_KEY";
$url = "https://inlomax.com/api/data";

$data = [
    "serviceID" => "100",
    "mobileNumber" => "08012345678"
];

$headers = [
    "Content-Type: application/json",
    "Authorization: Token $apiKey"
];

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
?>

Example Response:

{
    "status": "success",
    "message": "Dear Customer, You have successfully gifted 0903837261 with 1.0GB of Data. Thank you.",
    "data": {
        "type": "data",
        "reference": "INL|NQJK56QVZVHHX34RJ5XTMDXLG",
        "amount": 1000,
        "dataPlan": "5GB",
        "dataType": "SME",
        "network": "MTN",
        "status": "success"
    }
}

Step 4: Handle API Responses

Always verify success or failure messages and log them.
If the response status is “failed,” you can retry as you are refunded automatically to your wallet.

Best Practices for Smooth API Integration

To ensure your app runs smoothly, follow these simple practices:

Use HTTPS for all requests
Store transaction logs in your database
Handle retries for failed transactions
Test every service endpoint before launching
Secure your API key (never expose it publicly)
