The Docparser n8n integration works through these steps:

1. Document Input - Documents arrive via email, upload, or other sources
2. Automated Parsing - Docparser extracts specific data points based on your rules
3. Data Transformation - n8n processes and formats the extracted data
4. System Integration - Clean data flows to your business applications

The integration uses HTTP Request nodes to connect with Docparser's API, allowing for custom data extraction rules and seamless connection to your essential business systems like accounting, CRM, or inventory management.
