Slack or Discord Webhook Not Working
If your webhook notifications aren't being delivered, follow these steps.
1. Use the Test Button
The simplest way to diagnose webhook issues:
- Open the monitor's Settings tab
- Find the Slack or Discord webhook section
- Click Test
- Check the target channel for the test message
If the test fails, the webhook URL is likely incorrect or the webhook has been deleted.
2. Check the Webhook URL Format
- Slack URLs must start with
https://hooks.slack.com/services/ - Discord URLs must start with
https://discord.com/api/webhooks/
Make sure you copied the full URL without any trailing spaces.
3. Webhook Was Deleted or Revoked
If someone deleted the webhook from your Slack workspace or Discord server, the URL will no longer work. Create a new webhook and update it in Blimey.
4. Channel Permissions
Make sure the webhook still has permission to post in the target channel. In Discord, check that the channel hasn't been restricted since the webhook was created.
5. Save Before Testing
You must click Save before clicking Test. The test button sends to the currently saved URL, not the URL in the input field.
