How do you POST data to a multi-page google form?

Question

I'm trying to auto-fill a google form via POST. However when I actually POST the data to it, only the first pages questions actually get filled.

Example Code:

    private static void PostToFormTest()
    {
        WebClient client = new WebClient();
        var keyValue = new NameValueCollection();
        keyValue.Add("entry.843521592", "Option 1");
        keyValue.Add("entry.901429584", "Test Right Now");
        keyValue.Add("entry.347619935", "Test Page 2");
        Uri uri = new Uri("https://docs.google.com/forms/d/1zuQxyoRUQ-jYwTf7wrPu9Wqln8ec7gfhzRbOILD3LGU/formResponse");
        byte[] response = client.UploadValues(uri, "POST", keyValue);
        string result = Encoding.UTF8.GetString(response);

    }

Add this key in your NameValueCollection.

keyValue.Add("pageHistory", "0,1,2");//Comma separated page indexes (this is for 3 pages`enter code here`)

You are posting to a URL that only has 2 of the key value pairs:

// On page #1.
keyValue.Add("entry.843521592", "Option 1");
keyValue.Add("entry.901429584", "Test Right Now");

// On page #2.
keyValue.Add("entry.347619935", "Test Page 2");

The value for the second page cannot be added as the question does not exist when you post to the first page.

In short, there is no way to post to a multi-page form? – Douglas Gaskell Nov 23 '15 at 08:38
I don't think you can by using Google forms. I looked in to this previously. I know that Infiniforms (www.Infiniforms.io) are planning to add similar functionality to their forms soon. – Karl Gjertsen Nov 23 '15 at 08:40
Gotcha. Grasping at straws here, but I noticed a field named `fbzx` that populates after you go past the first page, does this field have anything to do with stored data on your "session"? I also noticed that `pageHistory` populates as you go through the pages as well. – Douglas Gaskell Nov 23 '15 at 08:45
I played with several attempts for a while and couldn't get anything to work. The answers I could find didn't help me much either. Sorry. – Karl Gjertsen Nov 23 '15 at 08:47
Thanks, I'll keep digging for a bit, if I find an answer I will post it here. Otherwise I will mark yours as the answer. – Douglas Gaskell Nov 23 '15 at 08:48
Thanks. It would be interesting to hear what you find. – Karl Gjertsen Nov 23 '15 at 08:49

capture all the "entry.#" and then don't foget the pageHistory with total number of pages starting from 0 (like Puneet pointed out)
