Firing hCaptcha callback function for bypass token

I'm trying to bypass the hCaptcha in Discord Account Registration using selenium webDriver in C#. I'm using CapMonster Cloud API for solving the captcha itself and as response I'm getting bypass token.
The problem that I currently have is that I can't locate the callback function that I need to call/submit, in order to pass the hCaptcha.
I'm setting the bypass token into "g-recaptcha-response" and "h-captcha-response" textareas, but can't find a way to locate and call the callback function. There is no form to be submitted.

using selenium webDriver in C#
10/10 Would recommend doing discord captcha bypasses using:
PuppeteerExtraSharp/ExtraStealth
(as selenium has some obvious tracers)
Puppeteer has a lot more freedom in it's API as well as the fact that 2capthca is a much more popular method for solving h-captchas
I know this doesn't answer your question but i hope you look into this as a potential better alternative if you do not receive a more traditional answer.

You can do that with Anti-Captcha.com plugin which will do the job automatically. It injects its own callbacks, so when a token is ready it submits the form. If you ever have problems with plugin, support guys here will help you out.

Web communication has to happen in one of the methods defined on this page
So if anything is being sent and received from a server to the browser it has to be one among those methods. Generally the most common methods are POST and GET.
The statement "There is no form to be submitted" is somewhat confusing. A form is just display of fields to collect data from a user. In case a website does not need user input they do not show the form. They would instead capture the required data and send a POST request to the server (without the user ever noticing), in a manner similar to how a form would have sent the data. This is a normal behavior for almost all major websites. An example is google-analytics codes.
So what you need to look for is a POST request (mostly or PUT maybe GET - depends) where the data you are targeting is received or sent.
In your case there indeed is a form which displays the captcha (that is how you see it) and and associated POST request which does what you need.
Url for the post request on the captcha is POST /getcaptcha?s=xxxxxxxx-xxxe-xxxx-xxxx-xxxxxxxxxxxx HTTP/3
Url where it is sent is POST /api/v9/auth/register HTTP/3
These basics apply to any web communication and not just the website in question.

c# web api as jira webhook url

I have been tasked to implement a JIRA SMS notification(using Twilio) similar to its in-built email notification. I know this can be easily done using Zapier and Twilio.
But i am told to look for a workaround with out using Zapier.
The only option i think of now is to create a WebApi project that calls Twilio to send the SMS, host the WebApi project on a server and pass this URL as a WEBHOOK in JIRA.
For this i have created a C# class library which calls Twilio.
class
and after that i have added a new WebApi project for this solution and added the above class project reference.
and i have added a new controller:
controller
i am just calling the send method from the constructor with out any parameters which i think will do the job just from hardcoded number to a given number(in the controller.
but what i need is to pass in messageBody and recipientPhoneNumber from the JIRA webhook to this controller. Not sure how to do this.
As i am very new to WebApi's could some one please help me with the code. much appreciated.

Twilio Dev Evangelist here...
Mind dropping me a note at corey#twilio.com? I agree with the previous responses - this site may not be the best forum to support what you're looking for here, but I would be more than happy to directly help you out here.

but what i need is to pass in messageBody and recipientPhoneNumber from the JIRA >webhook to this controller. Not sure how to do this.
The way webhooks work is a little bit different than your assumption above. You cannot pass anything to JIRA webhook. JIRA POSTs data to the webhook (your API URL). Once you receive the data in your API controller action, you can construct a message body and recipient phone number (from e.g. user object passed in by JIRA; if that object doesn't have any phone number attribute, you might have to use a custom field).
As i am very new to WebApi's could some one please help me with the code. much appreciated.
No problem. I guess you have done the Twilio part alright already. Please visit MS docs to know more about Web API. You have to add a controller method so that it can be called by JIRA. So your final URL becomes this. You can then put this URL in JIRA as webhook. Replace hostname mycompany.com by your server hostname and change other url segments based on your situation.

Making an custom content outbound voice call from console client

I am trying to make an outgoing call using Twilio and C#.
I gave the (fromnumber, tonumber, twiliodemourl) as 3 parameters for initiate
outbound call.Then it is working with default twilio demo voice content.
Now i need to customize the voice content attribute and some other attributes
every time i trigger the initiate outbound call method
I have gone through Twilio docs i did not find any good option for customize the
content dynamically from the code using C# every time i send the request.
My client application running periodically to verify for any new messages and then
trigger initiateoutboundcall.
I don't have any custom URL to post any new XML which voice is looking for in 3rd
parameter of initiateOutBoundCall.
So is it required a external domain URL to customize the voice content dynamically from code?
If no please provide the options/sample i have to do it from C# console application.
I tried to use the twimlets.com to echo the custom text to speak in the call.
For text change it is working fine with custom text. But i am not sure whether twimlets.com/echo can be used for production use? Please confirm. Twimlets is not supporting some of the features which i am looking for like Gather input
like IVR message for outbound call.
Using Twilio Voice and C# client:
Voice Request using Twilio C# client?
Dial the number with custom voice content(). If user not responds leave a
voice mail with the custom voice content().
Dial the number with custom voice content (). If user responds, after reading
the message need to provide options like:
press 1 for repeat the same voice message.
press 2 to confirm the action on the message.
press 3 to send SMS for the voice message.
Need to get the response for each voice call / message?
For the sms it send i am getting response as "queued" instead of message sent.
Based on the SMS sent successfully or not i need to update some flag.
So how i can get the SMS reponse as "sent".
SMSMessage sms = twilio.SendSmsMessage(sFromNumber, sToNumber, sMessage);
Console.WriteLine("SMS Status::::::" + sms.Status);
Similarly I need the reponse for voice call once the call is ring id done.
But it is giving "queued".
var call = twilio.InitiateOutboundCall(sFromNumber,sToNumber, url);
Console.WriteLine("Call Status" + call.Status);
So please provide me options for doing it using Twilio.
It would be great if you provide any sample example using C#.

Twilio evangelist here.
You do need some kind of public URL that Twilio can make an HTTP request to once the outbound call is answered. This is how Twilio gets the instructions it needs in order to proceed with the live, in-progress call.
As you noted there are a number of free options for hosting static TwiML content. Twimlets is one. Twimlbin.com is another. Both services are free and great places to at least get started prototyping or setting up a simple MVP of your application, but bear in mind that if you expect a large amount of traffic or you need to build something with your own custom logic in it you'll probably want to move to something else.
That something else could be your own website hosted as as Azure Website (which you can also get for free). Moving to your own website also means that you can scale it as needed and you can start serving up dynamically generated TwiML instead of just being limited to dynamic TwiML as you basically are with Twimlets or Twimlbin.
If you want to process input from <Gather> and none of the Twimlets meet your needs, then you will likely need to look at the Azure option (or some kind of hosted website, doesn't have to be Azure). This will let you build your own custom logic in order to process the callers input and dynamically generate a TwiML response based on that logic.
Twilio provides helper libraries for TwiML generation and for building Twilio apps using ASP.NET MVC, which you can get from NuGet.
Lets say you want to go down the road of building you own custom Twilio app using ASP.NET MVC and hosting it using an Azure Website. In that scenario, using our helper libraries you could build an action method in your controller that returns the TwiML with the <Say> and <Gather> verbs. Something like:
var response = new TwilioResponse();
response.Say("Hello World");
response.BeginGather(new { action="http://example.azurewebsites.com/gather/" } );
response.EndGather();
You would provide the URL that executes that action method as the third parameter in the initiaizeOutboundCall method eg:
client.IntializeOutboundCall(FROM, TO, "http://example.azurewebsites.net");
Once the user enters their input, Twilio will request the URL you specified in the <Gather> verbs action parameter passing you an extra HTTP parameter named Digits, which you can grab in your action method and use in your app logic:
public void Gather(string Digits) {
var response = new TwilioResponse();
response.Say("You pressed " + Digits);
return TwiML(response);
}
To get the status of a phone call or an SMS, you can include use the statuscallback parameter:
SMS: var result = client.SendMessage(FROM, TO, BODY, "http://example.azurewebsites.net/status");
Voice: var result = client.InitiateOutboundCall(FROM, TO, VOICEURL, "http://example.azurewebsites.net/status");
Twilio will make HTTP request to the statusCallback URL's once the final status of the message or call is reached.
Hope that helps.

As of version 5.32 of the C# SDK, you can pass a dynamic twiml string into the CallResource.Update() method like so:
CallResource.Update(
twiml: "<Response><Say>Custom Message Here</Say></Response>"
pathSid: call.Sid);
Or even:
string customMessage = "<Response><Say>Custom Message Here</Say></Response>"
CallResource.Update(
twiml: customMessage,
pathSid: call.Sid);

Getting data from a webpage

I have an idea for an App that would really help me out in work but I'm not sure if it's possible.
I want to run a C# desktop application that will ask for a value. When a value is supplied, the application will open a browswer, go to a webpage and add the value into a form on an online website. The form is then submitted and a new page is loaded that contains a table of results. I then want to extract the table of results from the page source and write code to parse the result values.
It is not important that the user see's this happen in an actual browser. In other words if there's a way to do it by reading HTTP requests then thats great.
The biggest problem I have is getting the values into the form and then retrieving the page source after the form is submitted and the next page loads.
Any help really appreciated.
Thanks

Provided that you're only using this in a legal context:
Usually, web forms are sent via POST request to the web server, specifically some script that handles it. You can look at the HTML code for the form's page and find out the destination for the form (form's action).
You can then use a HttpWebRequest in C# to "pretend you are the form", sending a POST request with all the required parameters (adding them to the HTTP header).
As a result you will get the source code of the destination page as it would be sent to the browser. You can parse this.

This is definitely possible and you don't need to use an actual web browser for this. You can simply use a System.Net.WebClient to send your HTTP request and get an HTTP response.
I suggest to use wireshark (or you can use Firefox + Firebug) it allows you to see HTTP requests and responses. By looking at the HTTP traffic you can see exactly how you should pass your HTTP request and which parameters you should be setting.

You don't need to involve the browser with this. WebClient should do all that you require. You'll need to see what's actually being posted when you submit the form with the browser, and then you should be able to make a POST request using the WebClient and retrieve the resulting page as a string.
The docs for the WebClient constructor have a nice example.

See e.g. this question for some pointers on at least the data retrieval side. You're going to know a lot more about the http protocol before you're done with this...

Why would you do this through web pages if you don't even want the user to do anything?
Web pages are purely for interaction with users, if you simply want data transfer, use WCF.
#Brian using Wireshark will result in a very angry network manager, make sure you are actually allowed to use it.

Setup Http Post Server

I have a mobile application which I want to call a http post to pass a binary string and write it to a SQL Server. Can you please give me some examples of code in setting up a http post server (Server side code) to accept 2 values (brinary string & DeviveID string).
Any help, advice or links welcome....

I don't know the iPhone side, but from the C# side, you could either do it via HTTP GET variables (e.g. http://www.example.com/?string=foo&devive=bar) and handle your SQL in there.
You could also run a small program that has a listening Socket or TcpListener on whatever port you want, and then have a BeginRead() method active waiting for input from the iPhone app. Once the BeginRead() returns with some data, you could then handle your SQL.

You could create a WCF REST service for this (look up the WCF REST Starter Kit), but as a quick-and-dirty solution you could do something much simpler: Just create an ASP.NET page that processes incoming POST data in its Page_Load handler.
If your POST format is the same one used by browsers (var1=123&var2=456), you can just use Request.Form["var1"] on the page. See http://forums.asp.net/t/1464546.aspx
If your POST format is different (e.g. XML), use Request.InputStream. See http://schlueters.de/blog/archives/31-Manually-processing-HTTP-POST-data-in-an-aspx.html

You could setup a Web Method on the web server to handle the requests from the iPhone app. Then you just send the data as a normal HTTP POST and the web method would handle the data, and call the SQL Server stored procedure.

You should be able to check the Request object to see if the data was posted and then perform your call to SQL Server.
For example:
Request.Params.Get( "sampleParam" )
will return the value of a sampleParam. As long as the posting application, page, or device posted the data you are expecting you will be able to get to it.
