I have been trying to figure out how to send an attachment in webhooks. I've been trying hours but cannot figure it out. I've been reading the this but I still haven't had much link. I've also been reading the docs but struggling to understand. Can anyone assist me?

<pre><?php 

$url = "WEBHOOK URL HERE";

$headers = [ 'Content-Type: multipart/form-data; charset=utf-8' ];
$POST = [
    // Message
    "content" => "Hello World!",
    
    // Username
    "username" => "testuser",

    // File upload
    "file" => curl_file_create("image.gif", 'image/gif', 'image')

];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($POST));
$response   = curl_exec($ch);
var_dump($response);

I'm getting the error

"{"message": "Cannot send an empty message", "code": 50006}"

Replace

"file" => curl_file_create("image.gif", 'image/gif', 'image.gif')

With

"file" => curl_file_create(realpath("image.gif"), 'image/gif', 'image.gif')

<pre><?php 

$url = "WEBHOOK URL HERE";

$headers = [ 'Content-Type: multipart/form-data; charset=utf-8' ];
$POST = [
    // Message
    "content" => "Hello World!",
    
    // Username
    "username" => "testuser",

    // File upload
    "file" => curl_file_create(realpath("image.gif"), 'image/gif', 'image.gif')

];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($POST));
$response   = curl_exec($ch);
var_dump($response);

Above code is only upload your own server file to discord.

If you want to get file from other URL and upload to Discord then you need to upload same file first on your own server as temp and then set this temp file here..

"file" => curl_file_create(realpath($tempfile), 'image/gif', 'image.gif')

after the

$response   = curl_exec($ch);
unlink($tempfile); //delete temp file if you want.
