Slack notifications are silent

Slack integration is connected, but you're not getting Katalyz notifications in Slack. Here's how to diagnose.

Important: Katalyz notifications arrive as direct messages from the Katalyz bot in your Slack — there's no channel to configure on the Katalyz side. If you're expecting notifications in a shared team channel, that's not how it works today.

Step 1 — Check Slack notifications are enabled in Katalyz

1. Go to Settings → Notifications.
2. Confirm the Slack master toggle is On.
3. Check specific notification categories you care about — their Slack checkbox should be on.

Step 2 — Check Slack integration is connected

1. Go to Settings → Integrations.
2. Find Slack in the list.
3. Status should be Connected.

If disconnected, reconnect and re-authorize.

Step 3 — Look for the Katalyz bot DM in Slack

In your Slack client, look in the Direct messages list on the left for Katalyz (or "Katalyz app").

• If you've never opened it, it may be tucked under More / Apps instead of your recent DMs
• Notifications land in this DM — not in any team channel

If the DM doesn't exist at all, the Slack connection wasn't completed for your user — see Step 2 and reconnect.

Step 4 — Check Slack notification settings on your end

Slack itself may be suppressing notifications:

• Check your Slack Do Not Disturb status — messages still arrive but don't ping
• Check your Slack workspace's notification preferences
• Check device-level notification permissions (especially on mobile)
• Also check your Slack workspace notification preferences for apps / DMs specifically

Step 5 — Verify the event actually fired

Some Katalyz notifications only fire when specific events happen:

• "Buyer opened room" — only fires when a buyer actually opens it
• "Task completed" — only fires when marked done

If no trigger event occurred, no notification is sent. Check the relevant room's Activity tab to confirm the event you expect actually happened.

Step 6 — Frequency settings

In Settings → Notifications, check your Slack frequency setting:

• Instantly — notifications fire per event
• Daily — bundled into one message at the end of the day
• Never — no Slack notifications

If you're on Daily, notifications arrive in one batch, not real-time. If you're on Never, getting nothing is expected.

Step 7 — Try a test event

Trigger a known event to verify the pipeline:

1. Open a test room
2. Add a comment or complete a task
3. Check if the notification arrives in the Katalyz DM in Slack within a few minutes (instant mode)

Step 8 — Reconnect Slack

Sometimes a full disconnect + reconnect clears stuck state:

1. Settings → Integrations → Slack → Disconnect
2. Wait a minute
3. Connect again
4. Re-authenticate
