🧩 RevenueCPA Introduction

RevenueCPA is an exclusive Offerwall platform for incentivized campaigns. It helps publishers integrate offers into apps or websites so users can earn virtual currency.

How it works?

Users complete tasks or surveys via the Offerwall and earn virtual rewards. These tasks are shown based on the user’s country, device, and behavior.

⚙️ Integration

Steps to embed our Offerwall:

1. Go to Placements in your dashboard.
2. Copy your API Key and Secret Key.
3. Use this code:

<iframe src="https://revenuecpa.com/offer/[API_KEY]/[USER_ID]"></iframe>

Replace [API_KEY] with your API key and [USER_ID] with your user’s ID.

🔁 Postback Information

When a user completes an offer, our server sends a GET request with these parameters:

✅ Signature Validation:

md5(subid + transid + reward + secret)

PHP Sample Code:

<?php
$secret = "YOUR_SECRET";
$subId = $_GET['subid'] ?? '';
$transId = $_GET['transid'] ?? '';
$reward = $_GET['reward'] ?? '';
$signature = $_GET['signature'] ?? '';

if(md5($subId . $transId . $reward . $secret) !== $signature) {
    echo "ERROR: Signature doesn't match";
    exit;
}

if($_GET['status'] == 2) {
    $reward = -abs($reward);
}

if(isNewTransaction($transId)) {
    processTransaction($subId, $reward, $transId);
    echo "OK";
} else {
    echo "DUP";
}
?>
