How to Integrate Inlomax Data API to Automate Data Purchase (Full Guide for Developers)

If you’re building an app, website, or platform that allows users to buy data bundles automatically, the Inlomax API gives you a powerful, fast, and reliable way to make that possible.

In this post, we’ll show you how to use the Inlomax Data API endpoint to buy data directly from your code — with sample PHP integration and a real sample response.

What Is Inlomax API?

The Inlomax API is a simple and secure way for developers, fintech startups, and VTU resellers to connect their apps or websites to the Inlomax system.
It allows you to perform automated actions like:

Buying data and airtime
Paying TV cable and electricity bills
Checking account balances and transaction statuses

In this article, we’ll focus on the Data API endpoint — how to use it to buy data programmatically.

Introduction to the Data Endpoint

The Data Endpoint lets you send a POST request with a few parameters (your API key, service ID, and phone number) to purchase a data bundle instantly.

This is useful if you run:

A data reselling website
A mobile app for top-ups
A billing system or automation platform

API Endpoint: Buy Data

Endpoint:

POST https://inlomax.com/api/data

Headers:

Authorization: Token YOUR_API_KEY
Content-Type: application/json

Request Body Example:

{
  "serviceID" : "100",
  "mobileNumber" : "0903837261"
}

Replace:

YOUR_API_KEY with your actual API key (found in your Inlomax Developer Dashboard)
serviceID with the ID of the data plan you want to buy
mobileNumber with the recipient’s phone number

PHP Integration Example

Here’s how to integrate it using PHP and cURL:

<?php
$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://inlomax.com/api/data',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS =>'{
    "serviceID": "100",
    "mobileNumber": "0903837261"
  }',
  CURLOPT_HTTPHEADER => array(
    'Authorization: Token YOUR_API_KEY',
    'Content-Type: application/json'
  ),
));

$response = curl_exec($curl);
curl_close($curl);
echo $response;
?>

This PHP code connects to the Inlomax API and sends a POST request to buy a data plan instantly.

Sample Response

When the API request is successful, you’ll get a JSON response like this:

{
  "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"
  }
}

Meaning:

status — tells you if the request was successful
message — confirmation message
reference — unique transaction ID for tracking
amount, dataPlan, and network — transaction details
