POSTing cURL to Zapier Webhook

You need to json encode the data you are sending and set the content-type also:

Change:

$opts = array(    CURLOPT_URL             => 'https://zapier.com/hooks/catch/n/abcd',    CURLOPT_RETURNTRANSFER  => true,    CURLOPT_CUSTOMREQUEST   => 'POST',    CURLOPT_POST            => 1,    CURLOPT_POSTFIELDS      => 'guid='+ $_POST["guid"] + '&video_title=' + $_POST["video_title"] + '&email=' + $_POST["email"], );

to:

$data = array('guid' => $_POST["guid"], 'video_title' => $_POST["video_title"], 'email' => $_POST["email"]);$jsonEncodedData = json_encode($data);$opts = array(    CURLOPT_URL             => 'https://zapier.com/hooks/catch/n/abcd',    CURLOPT_RETURNTRANSFER  => true,    CURLOPT_CUSTOMREQUEST   => 'POST',    CURLOPT_POST            => 1,    CURLOPT_POSTFIELDS      => $jsonEncodedData,    CURLOPT_HTTPHEADER  => array('Content-Type: application/json','Content-Length: ' . strlen($jsonEncodedData))                                                                       );

This should work.

Your not sending the POSTFIELDS correctly, you need to use . not + and also you should be url encoding the string...

$opts = array(    CURLOPT_URL             => 'https://zapier.com/hooks/catch/n/abcd',    CURLOPT_HEADER          => false,    CURLOPT_RETURNTRANSFER  => true,    CURLOPT_POST            => true,    CURLOPT_POSTFIELDS      => http_build_query(array('guid' => $_POST['guid'], 'video_title' => $_POST['video_title'], 'email' => $_POST['email'])));

You don't receive it in Zapier because you haven't set the 'Child key' structure.Take a look at what you need to do inside the image below.

Keep in mind that in my case I wanted to catch the 'company_name'. You'll have to replace it with your own parameter. You can also define additional parameters or even completely change the 'Child key' structure.
