Submitting a Form Action Post for API, do I need a post route?

I am using the npm "twit" and it is ultimately posting Twitter Status Updates. I have the user fill out a form and the action of the form is a post request to a path like home/tweet/.

In my express router I have a route home/tweet/. The Form data isn't really being posted there though, the reason I am doing this is because I am extracting the form fields qith req.body and then inside the router I am making the post request to Twitter to create a new tweet. Here is what it looks like:

router.post("/tweet/", function(req,res){
    var tweet = req.body.tweet;
    Twitter.post('statuses/update', { status: myFuncs.encode(myFuncs.key, tweet) }, function(err, data, response) {

    });
    res.redirect('/');
})

Even though this works, it feels a little hacky to me. Is there a better way to design this? Is there a better way to extract the Form Fields without using a post request using req.body, or a get request using req.query?
