POSTing cURL to Zapier Webhook

Question

I'm trying to POST using cURL to a Zapier webhook.

Zapier is configured so that if I were to type their URL like so -- https://zapier.com/hooks/catch/n/[email protected]&guid=foobar

It will receive the post, but when I try to do the same thing with cURL, it does not seem to receive it.

Here's my code for posting with cURL -->

<?php
    // Initialize curl
    $curl = curl_init();

    // Configure curl options
    $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"], 
    );

    // Set curl options
    curl_setopt_array($curl, $opts);

    // Get the results
    $result = curl_exec($curl);

    // Close resource
    curl_close($curl);

    echo $result;
?>

When I run this, it displays success, but Zapier does not receive it.

On Zapier's docs, someone gave an example with a proper cURL post, like so -->

curl -v -H "Accept: application/json" \
        -H "Content-type: application/json" \
        -X POST \
        -d '{"first_name":"Bryan","last_name":"Helmig","age":27}' \
        https://zapier.com/hooks/catch/n/Lx2RH/

I'm guessing that I'm missing something in the PHP file, help greatly appreciated!

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.
