First download and install Google API from here:

Add a reference to “Google Data API Core Library”,
and use the following function:

public static bool AddPost(string title, string bodyHTML, string[] labels)
    Service service = new Service(“blogger”, “<program name>”);
    service.Credentials = new GDataCredentials(“<username>”, “<password>”);
    AtomEntry newPost = new AtomEntry();
    newPost.Title.Text = title;
    newPost.Content = new AtomContent();
    newPost.Content.Content = bodyHTML;
    newPost.Content.Type = “html”;
    foreach (string label in labels)
        AtomCategory cat = new AtomCategory();
        cat.Scheme = new Uri(“”);
        cat.Term = label;
    AtomEntry response = null;
        response = service.Insert(new Uri(“<uri>”), newPost);
    catch (GDataRequestException exception)
        if (exception.ResponseString == “Blog has exceeded rate limit or otherwise requires word verification for new posts”)
            return false;
            throw exception;
    if (response == null)
        throw new Exception(“Something went wrong”);
    return true;

Note what you need to replace:

  • <program name>
  • <username>
  • <password>
  • <uri>

Also note the marked yellow line. It took me some nasty googling time to find it. You must put it for the labels to work.
