Message Format
Notifications use Block Kit with color-coded attachments:
| Color | Meaning |
|---|---|
🟢 Green (#00ff00) | Success |
🔴 Red (#ff0000) | Failure |
🔵 Blue (#3b82f6) | Informational |
Each message includes header, summary, structured fields (job name, duration, size), and timestamp.
Channel Override
The Channel field overrides the default channel configured in the webhook (e.g., #production-alerts or @username for DMs).
WARNING
Channel override only works if the Slack app has the chat:write scope. Standard Incoming Webhooks without this scope always send to the configured channel only.
Troubleshooting
403 - invalid_token
Verify the webhook URL is complete. Check the Slack app hasn't been uninstalled, or regenerate the webhook.
404 - channel_not_found
The channel override target doesn't exist or is archived. Verify the name with # prefix. For private channels, invite the bot first.
403 - team_disabled
The Slack app was removed. Reinstall it in your workspace settings.
