    "by passing some parameters along in the URL as a post request" POST parameters don't go in the URL. Please clarify. – yaakov May 23 '16 at 11:24

  • i meant something like https://example.com?email=krkapil@gmail.com&pass=password – Kapil Rathore May 23 '16 at 11:54
  • i tried that example but its not working – Kapil Rathore May 23 '16 at 11:55
  • @KapilRathore The example you shown was a GET request example. As @codran stated, POST parameters don't go in the URL. If you need to send POST, via `WKWebView`, [this answer](http://stackoverflow.com/a/1143020/1492173) might help you. – Yevhen Dubinin May 23 '16 at 13:44
  • @EugeneDubinin. That answer uses UIWebView, not WKWebView. – Mike Taverne May 23 '16 at 23:27
  • @MikeTaverne it does not matter in this case - `WKWebView` has similar method: `- (nullable WKNavigation *)loadRequest:(NSURLRequest *)request` where the `NSMutableURLRequest` from aforementioned answer could be submitted to. – Yevhen Dubinin May 24 '16 at 09:15

    @EugeneDubinin Yes, it does matter. The answer you referred to sets HTTPBody which unfortunately does not work for WKWebView due to this bug https://bugs.webkit.org/show_bug.cgi?id=145410 – Mike Taverne May 24 '16 at 18:25
  • @MikeTaverne that actually change everything related to the subject! The discussion on the bug gives some workaround with JavaScript. I did't double-check it myself, though. Meanwhile, from discussion it wasn't clear to me whether or not someone's gonna fix it any time soon. – Yevhen Dubinin May 25 '16 at 13:40

var request = new NSMutableUrlRequest(new NSUrl(new NSString(paymentwebview.url))); //Your Url
request.HttpMethod = "POST";
request.Body = NSData.FromString(paymentwebview.data); //Data for POST
request["Content-Length"] = request.Body.Length.ToString();
request["Content-Type"] = "application/x-www-form-urlencoded charset=utf-8";
LoadRequest(request);

Had a similar problem. What worked for me was passing the parameters as cookies.

Code example:

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod: @"POST"];
NSString *params = @"param1=value1;param2=value2;";
[request addValue:params forHTTPHeaderField:@"Cookie"];
[self.webView loadRequest:request];

Hope it helps!
