Sendgrid API - invalid username / password error

Question

I am trying to send my first email using Sendgrid:

$sendgrid = new SendGrid('username', 'xx.xxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxx'); $email = new SendGrid\Email(); $email->addTo(" [e-mail] ") ->setFrom(" [e-mail] ") ->setSubject("Sending with SendGrid is Fun") ->setHtml("and easy to do anywhere, even with PHP"); 

Here is the error I encountered:

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

Instead of "username" and "xx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" I, of course, use the real API key information from the Sendgrid settings:

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

Where can I get authorization information so that I don't get a Bad username / password error?

Answer 1

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

 $sendgrid = new SendGrid('xx.xxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxx'); $email = new SendGrid\Email(); $email->addTo(" [e-mail] ") ->setFrom(" [e-mail] ") ->setSubject("Sending with SendGrid is Fun") ->setHtml("and easy to do anywhere, even with PHP"); 

Answer 2

Instead of using the username, which is the name of the API key, try using the SendGrid username (the username that you use to access the control panel, etc.).

EDIT: for it to work, also use the Sendgrid password instead of the API key. It worked for me.

EDIT 2: while this solves the problem, you only need to use the api key, as indicated in the selected answer.
