Sendgrid-php: 401 Unauthorized

[xorb0ss]

I'm trying to implement a contact form, however upon submission, I get a 401 from sendgrid

echo $response->statusCode(); == 401

<?php
       require 'vendor/autoload.php';

      $apiKey = getenv('SENDGRID_API_KEY');
      $sendgrid = new \SendGrid($apiKey);

    if (isset($_POST["submit"])) {
        $name = $_POST['name'];
        $email = $_POST['email'];
        $message = $_POST['message'];

        if (!$_POST['name']) {
            $errName = 'Please enter your name';
        }

        if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
            $errEmail = 'Please enter a valid email address';
        }

        if (!$_POST['message']) {
            $errMessage = 'Please enter your message';
        }

if (!$errName && !$errEmail && !$errMessage) {
    $from = new SendGrid\Email(null, "$name");
    $subject = "Hello World from the SendGrid PHP Library!";
    $to = new SendGrid\Email(null, "[email protected]");
    $content = new SendGrid\Content("text/plain", "$message");
    $mail = new SendGrid\Mail($from, $subject, $to, $content);

    $response = $sg->client->mail()->send()->post($mail);
    echo $response->statusCode();
    echo $response->headers();
    echo $response->body();
}
    }
?>

Any ideas?

@xorb0ss,

This means your API Key either is not valid or set properly.

First, I would suggest that you print the value of $apiKey and ensure it is set properly.

If your API Key is set properly, please reach out to https://support.sendgrid.com to check on the status of your API Key's permissions.

Thank you!

Yup, I've printed $apiKey and it's correctly set to what I have in

sendgrid.env

@thinkingserious
I've actually tried putting my API key in directly to test, instead of

getenv('SENDGRID_API_KEY')

And that gives me error 400

@thinkingserious
Problem fixed - created a new API key and it seems to work

[thinkingserious]

Awesome, thanks for following up!

hey @xorb0ss ,
can you please describe what permissions should we give to a general key while creating one on SendGrid portal? which is used for purpose of sending emails from Azure webapp.

Hello @pganeshGapps,

Please reach out to our support team for help on our permission options. They can be reached at https://support.sendgrid.com

            curl_close($curl);

            if ($err) {
                //echo "cURL Error #:" . $err;
            } else {
            //echo $response;
                $response = json_decode ( $response );
                //print_r ( $response );
            }`

Hi @dudenk,

I'm glad you got it working. If you ever decide to use this lib for future work, please create a new issue and I'll help work through it with you.

With Best Regards,

Elmer

please change your $apiKey
from
$apiKey = getenv('SENDGRID_API_KEY')
to
$apiKey = 'SENDGRID_API_KEY';
