Sendgrid multipart / alternative image from base64

Question

I cannot get Sendgrid (using node.js) to send an email with an embedded base64 image in html. I think I'm pretty close ...

var base64img='data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAQgAAAFXCAYAAABeLtDdAAAgAElEQVR4Xu19CXhURdb2ISsJgSQ';//shortened version sendgrid.send({ to : ' [e-mail] ', from : ' [e-mail] ', subject : 'email with image from base64 data', headers:{ 'Content-Type': 'multipart/alternative; boundary="imagebase64"'+ '--imagebase64'+ 'Content-Type: image/png; name="base64.png"'+ 'Content-Disposition: inline; filename="base64.png"'+ 'Content-Transfer-Encoding: base64'+ 'Content-ID: <0123456789>'+ 'Content-Location: base64.png'+ base64img+ '--imagebase64' }, html : '<img src="cid:0123456789"/>' }); 

Can someone help as I cannot find an example of closure in sendgrid or google docs
