Testing Send endpoint for Gmail API with Postman

Question

I am trying to send emails with the Gmail API. I am trying to use Postman to test my requests and get the proper code to use in my web application, but I keep getting this error:

{
  "error": {
    "errors": [
        {
            "domain": "global",
            "reason": "invalidArgument",
            "message": "Recipient address required"
        }
    ],
    "code": 400,
    "message": "Recipient address required"
   }
}

I'm using the following link to make a POST request:

https://www.googleapis.com/upload/gmail/v1/users/me/messages/send

In my header, I have the following:

Authorization: Bearer ya29.xxxxxxxxx
Content-Type: message/rfc822

In my request body:

{

"raw" : "RnJvbTogQWxleCBCdWhzZSA8YWxleGJ1aHNlMUBnbWFpbC5jb20-IApUbzogQWxleCBCdWhzZSA8a29vX29saW9AaG90bWFpbC5jb20-IApTdWJqZWN0OiBTYXlpbmcgSGVsbG8geW8KRGF0ZTogRnJpLCAyMSBOb3YgMTk5NyAwOTo1NTowNiAtMDYwMApDb250ZW50LVR5cGU6IHRleHQvaHRtbDsgY2hhcnNldD11dGYtOA=="

}

I have tested the request with through the API testing sidebar on Google's own documentation:

https://developers.google.com/gmail/api/v1/reference/users/messages/send

but I seem to not be having any luck with using it in Postman. I'm using Postman and not the javascript that Google provides because I want to get the proper formatted code for making an AJAX call. I was wondering if anyone has worked with Postman and the Gmail API that may be able to help?

Figured out where I was going wrong. I changed content-type to:

Content-Type: application/JSON

And I changed the request link to:

 https://content.googleapis.com/gmail/v1/users/me/messages/send

And that fixed my issue.
