Trigger

Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Table Schema

Why this helps
A data insert can fail or lose useful detail when the destination table structure is unclear.
- See the destination columns and types before inserting.
- Reduce avoidable mismatches between extracted results and a table.
- Make the next data instruction more specific.
Setup
Build it in a few focused steps.
- 1Connect Affinda and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, or describe it to Notis in plain language.
- 3Tell Notis which ClickHouse table to inspect and ask it to compare the incoming Affinda result with that table's columns.
- 4Choose the notis_webhook trigger and select where run reports should go.
- 5Test with one real result and review the schema findings before using an insert workflow.
