How to send email using SendGrid

I have been trying to set up email for a web page using SendGrid's PHP API, and I'm having no luck. I have tried their code from the Azure website as well as various examples I found while trying to Google it, and every time it returns nothing as a response, and the email isn't set. Here is the code I'm talking about:

<?php
 $url = 'https://api.sendgrid.com/';
 $user = 'USERNAME';
 $pass = 'PASSWORD'; 

 $params = array(
      'api_user' => $user,
      'api_key' => $pass,
      'to' => '[email protected]',
      'subject' => 'testing from curl',
      'html' => 'testing body',
      'text' => 'testing body',
      'from' => '[email protected]',
   ); 

 $request = $url.'api/mail.send.json';

 // Generate curl request
 $session = curl_init($request);

 // Tell curl to use HTTP POST
 curl_setopt ($session, CURLOPT_POST, true);

 // Tell curl that this is the body of the POST
 curl_setopt ($session, CURLOPT_POSTFIELDS, $params);

 // Tell curl not to return headers, but do return the response
 curl_setopt($session, CURLOPT_HEADER, false);
 curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

 // obtain response
 $response = curl_exec($session);
 curl_close($session);

 // print everything out
 print_r($response);
 ?>

It is also worth noting that I've tried using sendgrid-php accompanied with the code supplied with it, and that causes the page to simply not load. I'm really stumped right now, and any help is greatly appreciated.

By default, Azure doesn't generate a SSL peer certificate for Azure Web Apps. If you add the code in your test code $error = curl_error($session);, you will get the error SSL certificate problem: self signed certificate in certificate chain.

You can simply add the code curl_setopt($session, CURLOPT_SSL_VERIFYPEER, 0); to bypass the verification.

Otherwise, you can follow Verify Peer Certificate from PHP cURL for Azure Apps to add a certificate on Azure Web Apps.

It's possible your version of cURL doesn't support SSL out of the box.

You can test this by putting the following at the top of your code:

if (!curl_version()['features'] & CURL_VERSION_SSL) {
    echo "SSL is not supported with this cURL installation.";
}

If it's not supported out of the box you have to configure it manually like this:

curl_setopt($session, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($session, CURLOPT_SSL_VERIFYHOST, 2);
// path to CA certificate
curl_setopt($session, CURLOPT_CAINFO, '/etc/openssl/cert.pem');
