Question

I created a web application that is using the outlook rest api V2.0.
I can authenticate the user en get the mail massages en calendar items. Problem is when i want to send a mail i am getting http error 400.
My outlook.php file
<?php
class OutlookService
{
private static $outlookApiUrl = "https://outlook.office.com/api/v2.0";
public static function stuurEmail($access_token, $user_email, $data)

}
public static function sendMail ($access_token,$user_email)
{
$sentMessagesParameters = '{"Message":{"Subject":"Meet for lunch?","Body":{"ContentType":"Text","Content":"The new cafeteria is open."},"ToRecipients":[{"EmailAddress":{"Address":"danny.herremans#rkg.vlaanderen"}}]},"SaveToSentItems":"true"}';
$json=json_encode($sentMessagesParameters, true);
$getMessagesUrl = self::$outlookApiUrl."/me/sendmail?".http_build_query($sentMessagesParameters);
return self::makeApiCall($access_token, $user_email, "POST",$getMessageUrl,$json);

public static function makeApiCall($access_token, $user_email, $method, $url, $payload = NULL)

// This function generates a random GUID.
public static function makeGuid()
{

$charid = strtolower(md5(uniqid(rand(), true)));
$hyphen = chr(45);
$uuid = substr($charid, 0, 8).$hyphen
.substr($charid, 8, 4).$hyphen
.substr($charid, 12, 4).$hyphen
.substr($charid, 16, 4).$hyphen
.substr($charid, 20, 12);
return $uuid;
}
}
}
?>
So in my home.php file i have the following code for sending the mail
if(isset($_POST['mailing']))
{
#extract($_POST);
$arr = '{
"Message": {
"Subject": "Meet for lunch?",
"Body": {
"ContentType": "Text",
"Content": "The new cafeteria is open."
},
"ToRecipients": [
{
"EmailAddress": {
"Address": "xxxxxxxxx#xxxx.xxx"
}
}
]
},
"SaveToSentItems": "true"
}';
$data=json_encode($arr, true);
$message = OutlookService::stuurEmail(oAuthService::getAccessToken($redirectUri), $_SESSION['user_email'], $data);
print_r($message);
echo"
<div class='alert alert-success'>
<a href='#' title='Sluit deze melding'
class='close' data-dismiss='alert' aria-label='close'>×
</a>
<br>".$_SESSION['access_token']."<br>".$_SESSION['user_email']."<br>$data<br>
</div>
";
}
When i wont to sent a mail i am getting the following error:
Warning: http_build_query(): Parameter 1 expected to be Array or Object. Incorrect value given in /var/www/vhosts/rkgvlaande05001/test/outlook.php on line 14 Array ( [errorNumber] => 400 [error] => Request returned HTTP error 400 )
Any idea what not right in the code or has anyone has a working example for the outlook rest api V2.0?
Thx

I checked you code and the sentMessagesParameters content is correct. However, I found this post mentioned, "you need to 'send mail as a user' permission for O365 Exchange Online in Azure AD if you want to send a mail message with REST API ". Please see the following link:
