A.1 Slack

The first and best-supported protocol is Slack. Developers wishing to support new protocols should consider Slack the “gold standard”. Gopherbot uses the slack-go/slack library.

The Message struct for Slack will have an .Protocol value of robot.Slack, and .Incoming pointer to a robot.ConnectorMessage struct:

• Protocol: slack
• MessageObject: *slack.MessageEvent
• Client: *slack.Client

Outgoing message formats

Slack is the most fully developed team-chat connector, but exact rendering can still vary a bit between Slack clients, notifications, and previews.

• BasicMarkdown
  • the normal v3 default for portable formatted output
• Variable
  • sent as literal variable-width text
• Fixed
  • sent as preformatted Slack content for code or aligned text
• Raw
  • passed through with connector-native interpretation

If you are trying to understand a formatting difference on Slack, start with the API formatting chapter and then use this appendix for Slack-specific expectations.
