    $post_data = array(
        "key"           => $this->API_KEYCODE,
        "addr"          => $address,
        "callback"      => "https://my-server.com/callback.php?customer_id=".$user_id."&secret=".$secret,
        "onNotification"=> "KEEP",

        "confs"         => $conf
    );

    Log::info('START SERVICE CALL :' . json_encode($url). " : ".json_encode($post_data));
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, count($post_data));
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post_data));
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER , array(
        "cache-control: no-cache",
        "content-type: text/plain",
    ));
    $ccc = curl_exec($ch);

    Log::info('END SERVICE CALL :' . $ccc);
    $json = json_decode($ccc, true);
    return $json;

this api successful return response in index id , address and callback url

second file callback.php

Log::info('TEST : START (BLOCKCHAIN Callback)========================================');
    Log::info('GET : '.jsone_encode($request));
    Log::info('GET : '.jsone_encode($_GET));
    $res = 'Nothing';

    $out_address = $_GET['secret'];
    $in_address = $_GET['address'];
    $user_id = $_GET['customer_id'];

    $transaction_hash = $_GET['transaction_hash'];
    $confirmations = $_GET['confirmations'];
    $value_in_satoshi = $_GET['value'];
    $value_in_btc = $value_in_satoshi / 100000000;

    $status = true;

    if($status == true) {

                $res = "*ok*";
        } else {
            //Waiting for confirmations


            $res = "Waiting for confirmations";
        }
    }
    Log::info('RES : '.$res);
    Log::info('TEST : END (BLOCKCHAIN Callback)========================================');

Answer 1

It's not about your code; it's from Blockchain.info.

I've made a transaction right now and never received the callback.

Blockchain.info always has these types of issues from time to time.

Please aware an issue with gap limit also. They may say that you've created 20 unused addresses and you're not.
