Slack Issues
Fix missing Slack notifications, duplicates, and webhook errors. Check webhook config, test the connection, or reconnect from scratch.
Slack notifications require a valid incoming webhook. If notifications stop arriving, check the webhook configuration below.
Notifications Not Appearing
- Go to Settings → Integrations
- Verify Slack shows as connected
- Click Send Test to test the connection
The Slack channel may have been deleted or renamed. Create a new webhook if needed.
Verify you've enabled the notification types you want (build started, succeeded, failed).
Webhook Errors
"Invalid webhook URL"
The URL format is incorrect or the webhook was deleted.
Fix:
- Create a new webhook in Slack
- Copy the full URL including
https:// - Update the webhook in Jamdesk
"Channel not found"
The target channel no longer exists.
Fix:
- Create a new webhook pointing to an existing channel
- Update the webhook URL in Jamdesk
"Posting to channel failed"
The webhook may have been revoked or the bot was removed.
Fix:
- Check Slack workspace settings for Jamdesk
- Re-create the webhook if needed
Duplicate Notifications
You may have multiple webhooks configured:
- Go to Settings → Integrations
- Remove duplicate Slack connections
- Keep only one webhook per channel
Delayed Notifications
Notifications typically arrive within seconds. Delays may be caused by:
- Slack service issues (check Slack Status)
- Network congestion
- Large build queues
Reconnecting Slack
To reset your Slack integration:
In Jamdesk, go to Settings → Integrations → Disconnect Slack
In Slack, create a fresh incoming webhook for your channel
Add the new webhook URL in Jamdesk
Click Send Test to verify it works
Notification Format Issues
If messages appear malformed:
- Ensure you're using Incoming Webhooks (not Slack API)
- Check that your Slack workspace allows external webhooks
