A Slackbot is a slack app or a tool. It lets you interact with teammates, employees, and leaders in the office. It is like a handy robot assistant that waits for commands and responds accordingly.

API Call for Slackbot

You have to handle slack events in the slack channel. It is because a Slackbot responds to predefined events. When a developer mentioned the bot, it receives a triggered event. Websocket is used to deliver events.

You have to add event subscriptions. Developers can find it in the features tab and activate it. Now add the app_mention scope to event subscriptions. This way you include a new event in the application.

Furthermore, you have to generate an application token. Here are the steps that you have to follow.

Step 1. Settings

Step 2. Basic information

Step 3. App-level tokens

Step 4. Generate token and scope

Step 5. Give a name to the token

You have to save the token by writing the .env file as SLACK-APP-TOKEN. Add a sub package of slack-go. It is called socketmode. It is important to use socket mode.

Furthermore, you have to create a new client for the socket mode. Connect the WebSocket client by calling socketmode. At the end socketClient.Run() helps to process new web socket messages. SocketClient.Events channel is to get messages. Go routine is also important to handle messages in the background.

You have to trigger an event on the event API in slack.

Run the program and enter the slack app and web. Mention by the bot using @yourbotname.

The event is logged in the command line to run the bot. You get the event_callback, it contains a play load with the actual event. Now you have to begin to implement the HandleEventMessage. It will continue the type switching.

Furthermore, you can reach and use payload events with the help of InnerEvent.

At this stage, you have to replace the previous log in the main function. It will print the event with the new HnadleEventMessage function.

Now you have to follow some steps.

1. Start by logging into the application
2. Add the users:read
3. After adding scope to the token
4. Create HandleAppMentionEventToBot function

You can fetch user details with the help of a user ID in the event.User. You will need event.text to fetch the actual message.

At this stage, restart the program and say hi or send any other message. This way, you can check whether the Slackbot working properly or not. if you see “missing_scope” error.
