MVP workflow approvals in Slack cut the delay between work and launch. No switching apps. No chasing sign-offs over email. The approval sits where your team already talks, and action happens instantly.
The setup is straightforward. Define the workflow states—pending, approved, rejected. Tie them to Slack channels or direct messages. Add user roles, so only the right people can approve. Use structured Slack message blocks with interactive buttons to trigger backend calls. Handle authentication through your existing identity provider or Slack’s user tokens.
Integrate your system of record. This could be GitHub for code reviews, a CI/CD pipeline for deployments, or a ticket tracker for change requests. When a workflow hits an approval stage, your backend posts a Slack message with context: title, description, linked resources. One click gives an approval, posts back to the API, updates the record, and moves the process forward.
