Robot example code

Robot code explained

• We added the RPA.Notifier library in the *** Settings *** section.
• We set the ${SLACK_WEBHOOK_URL} variable with the Webhook URL we got from Slack.

  NOTE: You should not use the webhook URL directly in your code. This is a good use case for the Vault feature of Control Room.

• We set the ${CHANNEL} variable with the name of the channel we want to send the message to.

  NOTE: even if the Incoming Webhook app needs to be added to a specific channel, you can enter any public channel here.

• We added a new task: Send a message to a Slack channel.
• In our task, we used the Notify Slack keyword from the RPA.Notifier library, passing it the text of the message, our channel variable, and the webhook URL as arguments.

Running the robot sends the message to the channel in Slack.
