Slack provides HTML you can use to help Slack users find your bot in the Add the Slack button section of this page. To use this HTML with your bot, replace the href value (begins with https://) with the URL found in your bot's Slack channel settings. Follow these steps to get the replacement URL.

  1. On, click your bot.
  2. Click Channels, right-click the entry named Slack, and click Copy link. This URL is now in your clipboard.
  3. Paste this URL from your clipboard into the HTML provided for the Slack button. This URL replaces the href value provided by Slack for this bot.

Authorized users can click the Add to Slack button provided by this modified HTML to reach your bot on Slack.


As of June 2020 Slack channel supports Slack V2 permission scopes which allow the bot to specify its capabilities and permissions in a more granular way. All newly configured Slack channels will use the V2 scopes. To switch your bot to the V2 scopes, delete and recreate the Slack channel configuration in the Channels blade. The link you pasted into the href value of the HTML contains scopes that can be refined as needed. Consult for the full list of available scopes.
