Slack is a messaging app for businesses that improves communication, teamwork, and decision-making. It allows people to collaborate easily, work on their own time, and share information in dedicated chat spaces.

Before setting up

Before you can connect you need to make sure that you have a Slack account and you are part of a specific workspace.

Enable webhooks

If you want to use Slack webhooks, you’ll need to add Blackbird bot to the channels you’re interested in after you’ve created a connection. There are two ways to do this.

The first way:

  • Select a channel.
  • Send a message with @Blackbird content.
  • Click Add to channel.
  • Do the same for other channels you’re interested in.

The second way:

  • Go to the channel you selected during connection creation.
  • Find added an integration to this channel: Blackbird message.
  • Click on Blackbird -> Add this app to a channel… -> select a channel from dropdown.
  • Do the same for other channels you’re interested in.
