The n8n Google BigQuery integration works through a straightforward yet powerful approach:

1. Authentication: Connect securely using Google's OAuth or service accounts
2. Node-Based Configuration: Drag-and-drop BigQuery nodes into your workflow
3. Two-Way Data Flow: Both read from and write to BigQuery
4. Trigger Capabilities: Initiate workflows based on query results or schedules
5. Transform & Process: Manipulate data before/after BigQuery operations

This architecture enables powerful use cases like automated ETL processes, real-time data synchronization, scheduled reporting, and event-driven analytics—all configured through an intuitive visual interface rather than complex coding.
