 * Hi, I’ve tried setting up Postman SMTP with the Gmail API, and it will not, no
   matter what I do, send the test email.
 * I am always confronted with the error code: Error calling POST [https://www.googleapis.com/gmail/v1/users/me/messages/send](https://www.googleapis.com/gmail/v1/users/me/messages/send):(
   400) Bad Request
 * I have browsed the WordPress forums and Google results for hours searching for
   a fix to this, and have found nothing, created numerous Google API Client IDs
   to insert, and still no luck.
 * Are you able to help me out in any way? Thank you very much.
