Slack integration FAQ
Do I need to create my own auth app to connect Slack to StackOne?
Only if you use OAuth in production. Slack offers BYO OAuth (register a Slack app, paste Client ID and Secret), token auth (paste an
xoxb- or xoxp- token directly), and a StackOne-hosted app for testing only. Production OAuth requires your own Slack app from api.slack.com/apps. See the Slack auth docs.Put your AI agents to work
