Help with creating a proper postback script and url

I am looking for a freelancer who can help me with creating a proper postback script and URL for my project. I am using an existing script that needs modification that probably is wrong .m trying to create a functional postback url and script to communicate with cpx research. I have been trying to do this for a very very very long time , I gave up and now im back at it. Here is what I can share of the [login to view URL] script. <?php // Get the values from the postback URL parameters $status = $\_GET\['status'\]; $trans\_id = $\_GET\['trans\_id'\]; $user\_id = $\_GET\['user\_id'\]; $amount\_local = $\_GET\['amount\_local'\]; $amount\_usd = $\_GET\['amount\_usd'\]; $offer\_id = $\_GET\['offer\_id'\]; $ip\_address = $\_GET\['ip\_click'\]; // Validate the data and check for errors if ($status != "completed" && $status != "pending") { // Invalid status die("ERROR: Invalid status"); } // Perform the actions that you want to do with the data // Connect to your database using mysqli or PDO \*\*\*\*MY DATABASE LOGIN INFO\*\*\*\*\* // Create a mysqli object $conn = new mysqli($db\_host, $db\_user, $db\_pass, $db\_name); // Check for connection error if ($conn->connect\_error) { die("ERROR: Connection failed: " . $conn->connect\_error); } // Prepare and bind an SQL statement to insert or update the data in your table // Replace the table name and column names with your own $stmt = $conn->prepare("INSERT INTO offerwall\_history (user\_id, trans\_id, ip\_address, claim\_time, amount) VALUES (?, ?, ?, ?, ?) ON DUPLICATE KEY UPDATE claim\_time = ?, amount = ?"); $stmt->bind\_param("ssssis", $user\_id, $trans\_id, $ip\_address, $amount\_usd); // Execute the prepared statement if ($stmt->execute() === false) { // Handle execute error die("ERROR: Execute failed: (" . $stmt->errno . ") " . $stmt->error); } // Close the prepared statement and the connection $stmt->close(); $conn->close(); // Echo a response that indicates whether the postback was successful or not echo "OK: Postback received"; Here is what is required from cpx research [login to view URL] and with the script i made ( which I am sure is not correct ) I am getting this postback result from cpx [login to view URL] which shows status 1 in the links but the "status code" box shows 0 the result box is empty. Also nothing is updated in the cloums in my database which you can see here [login to view URL] . .
