  • You can optionally fill in a Success URL. If you leave this blank, the user will be redirected to their Slack team after installing your bot. This is usually a good thing to do, but if you prefer, type a different URL to send the user to here.
  • Now that's done, click Next to save those details and your bot is configured!
  • The final step invites you to install your bot into your own team. Follow the steps on screen. You'll also see the information you need to tell other people how to install your bot.

Inviting to Channels

Slack bots have to be invited to channels that they can then participate in. Once you or any of your users have installed your bot, they'll need to use the command "/invite @username" (replace @username with your bot's username) to invite into channels.

Distributing Your Bot

You should use the Slack Button to allow people to install and use your bot with just a few steps.

Slack has a simple code generator on their site to get the code you need to display the button. Choose the app you just created from the list and tick only the Bot option. Then copy the code and paste wherever you want the button to be shown.

Publishing to the Slack App Directory

When you're happy that your bot is working as you expect, you can apply to have the bot listed in the Slack App Directory. Slack has details on their site about how to add an app.
