Setting up Slack as an alerting channel is simple:
  1. First, install the Checkly Slack App into your Slack Workspace by going to your integrations page and click “Connect Slack Workspace”.
  2. Then, head to your alert settings, click “Add more channels” and select a new Slack channel.
Add a Slack WebHook URL to Checkly You can add any #public-channel-name, @username for Direct Messages or a channel ID. For private channels, the Checkly Slack app needs to be explicitly invited to that channel by tagging it like @Checkly.
If you’re using a free Slack workspace, be aware of message limits. Exceeding these limits may prevent new alerts from being delivered.

Example Failed Slack Alert

For each check and / or monitor, the Slack alert message contains key information, a possible root cause analysis and key actions like rerunning the check. A slack message showing a failed alert
The root cause analysis uses AI to analyze your logs, traces, test source code, error information and other artefacts available to Checkly. Be aware that AI can make mistakes so outputs should be verified independently.

Example Recovered Slack Alert

From the recovered Slack message, you can see the timestamp as well as a link to the check itself. A slack message showing a recovered alert

Migrating from the deprecated Slack webhook alert channels

Checkly previously only had Slack webhook based alert channels. These types of webhooks have been deprecated by Slack and are now also deprecated by Checkly. These webhook channels will keep working; we have not set a hard end-of-life date. You can recognize the deprecated channel in your alert channels list. It is named “Slack webhook” and has an alert icon. Deprecated Slack channel To help you migrate from the old webhook based alert to the Slack app based alerts, we added a “Convert to Slack App alert channel” button in each current webhook-based alert channel. Just click the button, confirm which channels you want to migrate or add new ones, and click “Create Slack App alert channel”. Convert to Slack App alert channel After this, you can safely delete the deprecated channel.
