Bot Service

Fill the following details and add the location based on our client location or our Geolocation.

Once the build is successful, click on the "Dashboard" and we can see that the "menothbotdemo" bot is created in the All resources list. Bot is ready for use!

Create a Slack Application for our Bot

First, we need to create a workspace in Slack Account. Check the following link to create a Slack Account: New slack account.

Create an app and assign a Development Slack team or Slack Workspace

Click on the URL https://api.slack.com/apps. Then, click on the "Create New App" !!.

Once the Slack workspace is created, then only we can create a slack application under the Workspace. Now, we are going to create and assign our slack app name into the Workspace. We have given our App a name as "menothbotdemo".

Click on the "Create App" button. Then, Slack will create our app and generate a Client ID and Client Secret. We can use these IDs for channel configuration in Azure Web App bot.

Add a new Redirect URL

Click on the "OAuth & Permission" tab in the left panel. Then, add the redirect URLs as "https://slack.botframework.com" and save it properly.

Create Bot Users

Click on the "Bot Users" tab in the left panel. Then, click on "Add a Bot User". In this section, we can give our bot "Display name". For example, we created our bot user's name as "menothbotdemo". If we want our bot to always show as Online, then click on the "On" button. After that, click "Add Bot User" button.

Channel Configuration

There is a very simple way to connect our bot service app to Slack in Azure. Just follow the following steps.

Click on the "Channels" menu on the left side option. Then, it will open a window with channel details where we can see "More channels" options. Then, select "Slack" in the channels list.

Add the following Slack App ( Already Created Slack App ) credentials into the Azure Slack configuration section.

  • ClientID
  • Client Secret
  • Verification Token

Once the configuration is done, we can see our Slack configured into the channel.

C# Code

We have done some changes in the default code in bot service.

using System; 
using System.Threading.Tasks; 
  
using Microsoft.Bot.Connector; 
using Microsoft.Bot.Builder.Dialogs; 
using System.Net.Http; 
  
  
namespace Microsoft.Bot.Sample.SimpleEchoBot 
 [Serializable] 
 public class EchoDialog : IDialog<object
 
 protected int count = 1; 
  
 public async Task StartAsync(IDialogContext context) 
 
 context.Wait(MessageReceivedAsync); 
 
  
 public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument) 
 
 var message = await argument; 
  
 &nb sp; if (message.Text == "reset"
 
 PromptDialog.Confirm( 
 context, 
 AfterResetAsync, 
 "Are you sure you want to reset the count?"
 "Didn't get that!"
 promptStyle: PromptStyle.Auto); 
 
 else if (message.Text == "Hi"
 
 await context.PostAsync($"{this.count++}: Slack Configured in Bot App !!"); 
 context.Wait(MessageReceivedAsync); 
 
 else 
 
 await context.PostAsync($"{this.count++}: You said {message.Text}"); 
 context.Wait(MessageReceivedAsync); 
 
 
  
 public async Task AfterResetAsync(IDialogContext context, IAwaitable<bool> argument) 
 
 var confirm = await argument; 
 if (confirm) 
 
 this.count = 1; 
 await context.PostAsync("Reset count."); 
 
 else 
 
 await context.PostAsync("Did not reset count."); 
 
 context.Wait(MessageReceivedAsync); 
 
  
 
}
