Slack DND API

Slack's Do Not Disturb (DND) API lets apps read and manage users' notification quiet time so they don't get pinged when they've paused alerts. With the dnd:read and dnd:write scopes, an app can check a user's current DND state and scheduled quiet hours, retrieve team-wide DND summaries (where permitted), start or extend a snooze for a specified duration, and end snooze or active DND. Key methods include dnd.info, dnd.teamInfo, dnd.setSnooze, dnd.endSnooze, and dnd.endDnd. Responses provide whether DND is enabled and timestamps for when it starts and ends, enabling apps to defer messages, schedule work, or adjust notification behavior. The API is designed to respect user preferences and workspace policies; apps should handle rate limits and note that they can set temporary snoozes but cannot programmatically change a user's full DND schedule.
