Is service account support in blogger api?

I am getting following with the code. I think blogger need to invite 
[email protected] but how [email protected] 
accept it using gmail?

{
  "code" : 403,
  "errors" : [ {
    "domain" : "global",
    "message" : "Forbidden",
    "reason" : "forbidden"
  } ],
  "message" : "Forbidden"
}



GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(HTTP_TRANSPORT)
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId("[email protected]")
.setServiceAccountScopes(BloggerScopes.all())
.setServiceAccountPrivateKeyFromP12File(
new File("9ffcc4041e16c0-privatekey.p12"))
.build(); 
System.out.println(credential.getRefreshToken());//null
 
// set up global Plus instance
Builder blog = new Blogger.Builder(HTTP_TRANSPORT, JSON_FACTORY,credential);
blog.setApplicationName("Service 
Account-bit60qa1hh08g8lhbl4h33vef4hdngvjs");
// blog.setApplicationName("Blogger-PostsInsert-Snippet/1.0");
 Post content = new Post();
content.setTitle("A test post");
content.setContent("With <code>HTML</code> content");
 Blogger blogger = blog.build();
Insert insert = blogger.posts().insert("6828107655361625046123", content);
insert.setIsDraft(false); 
insert.setFields("author/displayName,content,published,title,url");

Post post = insert.execute();
