Bring important changes in your analytics to the team without waiting for someone to notice them in a dashboard.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
Meaningful changes in business metrics can go unnoticed between manual checks.
- Kick off a data check from an HTTP request.
- Share only results that meet the threshold described in the prompt.
- Give the team a timely signal to investigate.
Setup
Build it in a few focused steps.
- 1Connect ClickHouse and Slack once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for the metric being monitored.
- 3In one instruction, describe the ClickHouse query, the threshold to check, and what Slack message to post when it is met.
- 4Choose a webhook as the trigger and select where run reports should go.
- 5Test with one real example that returns a result on each side of the threshold.
Questions about this workflow
Where does the threshold come from?
Include the threshold in the automation instruction. Notis evaluates the query result against the value you specify.
What starts this workflow?
An HTTP request to the automation's webhook starts it. ClickHouse itself does not provide the trigger event here.
