How do I make a VB webhook listener?

To receive notifications from a service, I want to utilise Visual Basic to build a webhook listener. The service is not listed under Microsoft in Nuget.AspNet.WebHooks.Receivers.*. An SSL certificate from a recognised root authority is necessary for the service.

Hi @charli puth,

Do you mean webhook doesn't support your service?

Because of their simplicity, WebHooks are already exposed by a large number of services including Dropbox, GitHub, Bitbucket, MailChimp, PayPal, Slack, Stripe, Trello, and many more.

Microsoft ASP.NET WebHooks is part of the Microsoft ASP.NET family of modules and is hosted as an Open Source Project on GitHub.

You can refer to ASP.NET WebHooks for development.

To create a webhook listener in VB (Visual Basic), you can follow these steps:

Set up your development environment: Ensure you have a compatible version of Visual Studio installed on your machine.

Create a new VB project: Open Visual Studio and select "Create a new project." Choose a Visual Basic Windows Forms Application or a Console Application, depending on your requirements.

Add required references: Right-click on your project in the Solution Explorer and select "Manage NuGet Packages." Search for and install the required packages such as Newtonsoft.Json for handling JSON data.

Implement the webhook listener code: In your VB project, open the code file associated with your main form or console application. You'll need to write code to create an HTTP server that listens for incoming webhook requests.

Here's an example using the HttpListener class:

Imports System.Net Imports Newtonsoft.Json.Linq Module WebhookListener Sub Main() Dim listener As New HttpListener() listener.Prefixes.Add("http://localhost:8080/") ' Set the URL where your webhook listener will be accessible listener.Start() Console.WriteLine("Webhook listener started. Waiting for incoming requests...") While True Dim context As HttpListenerContext = listener.GetContext() Dim request As HttpListenerRequest = context.Request If request.HttpMethod = "POST" Then Dim body As String Using streamReader As New System.IO.StreamReader(request.InputStream) body = streamReader.ReadToEnd() End Using ' Handle the received webhook payload Dim payload As JObject = JObject.Parse(body) ' Process the payload data according to your requirements ' Send an appropriate response back Dim response As HttpListenerResponse = context.Response Dim responseString As String = "Webhook received successfully" Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes(responseString) response.ContentLength64 = buffer.Length Dim output As System.IO.Stream = response.OutputStream output.Write(buffer, 0, buffer.Length) output.Close() End If End While End Sub End Module

Customize the code: Adapt the code according to your specific webhook requirements. You can process the received payload, perform actions based on the data, and send an appropriate response back to the webhook sender.

Test the webhook listener: Build and run your VB project to start the webhook listener. It will listen for incoming webhook requests on the specified URL (e.g., http://localhost:8080/). You can test the listener by sending a sample webhook request to that URL and verify if it receives and processes the payload correctly.

Remember to handle errors, add security measures, and customize the code further based on your specific webhook implementation needs.

The service calling you your webhook will require ssl with a signed certificate from a trusted authority. This means you need to buy the cert or use a host that already support ssl.
