Know which event fields are available before you build a metric.
Trigger
Webhook received

Action
Get Table Schema
Get detailed schema information for a specific table including column definitions, types, keys, and optionally sample data. this is essential for ai agents to understand table structure before constructing queries.
Why this helps
