Check the ClickHouse table before shaping an Ahrefs analysis
Start an on-demand schema check when you need to know which analytics fields are available for your Ahrefs research.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Table Schema
Gets the schema and column details for a table.
Why this helps
It is hard to write a useful analytics query when the table structure is unclear or easy to forget.
- See the selected table's available columns and types before composing a query.
- Avoid assumptions about fields that may not exist.
- Start a focused review from an HTTP request.
Setup
Build it in a few focused steps.
- 1Connect Ahrefs and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis the outcome in plain language.
- 3In one instruction, name the ClickHouse table to inspect and the Ahrefs question the available schema should support.
- 4Pick a webhook as the trigger and choose where run reports go.
- 5Test with one real example and verify the returned schema matches the intended table.
Questions about this workflow
Does the webhook itself query analytics?
This workflow uses the ClickHouse Get Table Schema action to inspect table structure. It does not run a SQL query.
Can it inspect every table automatically?
The selected action is for a specific table. Tell Notis which table to inspect; use ClickHouse's list tables action separately if discovery is needed.
