I am trying to send a calendar invite as an attachment through email using SparkPost but the invite does not open once the email is received. I use two files "calendarinvite.php" to create the invite and "Sendemail.php" to send the email.
the calendarinvite.php file creates the invite properly because when I run the script I can download the invite and open it. however, once it is sent as an attachment I can't open the invite.
Any help would be appreciated.
Sendemail.php:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
// include substr($_SERVER["DOCUMENT_ROOT"], 0, strrpos($_SERVER["DOCUMENT_ROOT"], '\\')) . '/thingzine/sparkpost/CalendarInvit.php';
// echo $ical;
// Function to Access SparkPost API:
function sparkpost($method, $uri, $payload = [], $headers = [])
{
$defaultHeaders = [ 'Content-Type: application/json' ];
$curl = curl_init();
$method = strtoupper($method);
$finalHeaders = array_merge($defaultHeaders, $headers);
$url = 'https://api.sparkpost.com:443/api/v1/'.$uri;
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
if ($method !== 'GET') {
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($payload));
}
curl_setopt($curl, CURLOPT_HTTPHEADER, $finalHeaders);
$result = curl_exec($curl);
curl_close($curl);
return $result;
}

This works for me:

Here is a sample CURL command. You will need to put the proper to/from address and your API key.
curl -X POST \
