   var data = JSON.stringify({"requestData":registerData});

In Action Class i am getting the request data

Content-Length: 231

Accept-Encoding: gzip, deflate

Accept: application/x-www-form-urlencoded

User-Agent: Zapier

Content-Type: application/x-www-form-urlencoded

So requestData is null, obviously. Would be helpful to know what the URL is. Typically, a URL would look something like this: www.url.com/page?key=value&key2=value2 - Christopher Schneider
You're using the wrong encoding. You're saying that you send application/x-www-form-urlencoded but you're sending a JSON string instead. You need to URL-encode your post parameters rather than JSON encoding. Other the request.getParameter call will not be able to retrieve the parameter - it doesn't even see any parameter because the encoding format is wrong. - Erwin Bolwidt
@ChristopherSchneider What do you mean? If you agree with me you can simply upvote the comment. - Erwin Bolwidt

This is caused by no "requestData" param, your submitted data is a JSON object itself. I think you should change your JS to

var data = 'requestData':JSON.stringify(registerData);
