title: Trying to make sure my credentials for Sendgrid with my API Key allows me access to send. message: Permission denied, wrong credentials
body: <p>I believe I'm overlooking something when it comes to the areas where I would enter my API key and/or other fields I changed for this package from github, s-ichikawa/laravel-sendgrid-driver (<a href="https://github.com/s-ichikawa/laravel-sendgrid-driver" rel="nofollow noreferrer">https://github.com/s-ichikawa/laravel-sendgrid-driver</a>). I've used the exact same API on another project and I'm pretty sure it's legit. I am also new to Laravel &amp; Php, and I 'm hoping someone could see my mistake on one of the files I edited while going down the step for installing.
  I get this exact <em><strong>error</strong></em></p>
  <blockquote>
  <p>Client error: <code>POST https://api.sendgrid.com/v3/mail/send</code> resulted in
  a <code>401 Unauthorized</code> response: {&quot;errors&quot;:[{&quot;message&quot;:&quot;Permission
  denied, wrong credentials&quot;,&quot;field&quot;:null,&quot;help&quot;:null}]}</p>
