Sendgrid API - Bad username / password error

Question

I'm trying to send my first email with Sendgrid:

$sendgrid = new SendGrid('username', 'xx.xxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxx');
$email = new SendGrid\Email();

$email->addTo("[email protected]")
      ->setFrom("[email protected]")
      ->setSubject("Sending with SendGrid is Fun")
      ->setHtml("and easy to do anywhere, even with PHP");

Here's the error I run into:

PHP Fatal error: Uncaught exception 'SendGrid\Exception' with message '{"errors":["Bad username / password"],"message":"error"}'

Instead of 'username' and 'xx.xxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxx' I of course use real API key info from Sendgrid settings:

I used the long string key provided after creating the API key. But there still seems to be something wrong with this line: $sendgrid = new SendGrid('username', 'xx.xxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxx');

Where should I get the info for authorization so that I don't get the Bad username / password error?

Answer 1

Another possible answer is to pass just the api key to the SendGrid() constructor;

$sendgrid = new SendGrid('xx.xxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxx');
$email = new SendGrid\Email();

$email->addTo("[email protected]")
      ->setFrom("[email protected]")
      ->setSubject("Sending with SendGrid is Fun")
      ->setHtml("and easy to do anywhere, even with PHP");
