This n8n workflow automates the weekly synchronization of QuickBooks Chart of Accounts data into Google BigQuery. Starting every Monday, it fetches accounts updated in the past week, processes and cleans the data, and then inserts or updates records in a designated BigQuery table. The workflow involves a schedule trigger, HTTP request to QuickBooks API, data transformation nodes, and a BigQuery insertion node. It provides a robust solution for financial analysts, data teams, and business owners to maintain an accurate, historical record of their financial account structures for reporting and analysis purposes.
