Data Processing Service

This workflow automates data processing for JSON, binary, and static data. Key nodes include Webhook Trigger (receives POST requests), Validate Input (checks operation), Prepare Processing Data (sets parameters), Route Processing Operation (directs tasks), Process JSON Data, Process Binary Data, Process Static Data, Process All Data Types (data processing), Success Response, Error Response, Check Binary Data, Include Binary Info, and Return Response (manage outputs). It handles structured JSON, binary file creation, and static data persistence without external APIs.\n\nSetup Requirements and Configuration: Install n8n by downloading from n8n.io for self-hosting or sign up at cloud.n8n.io for cloud setup. Follow installation prompts or create a cloud account. No external API credentials are needed as the workflow uses n8n’s built-in code nodes for processing. Import the provided JSON to create the workflow in n8n. Set the Webhook Trigger node’s path to 'data-processing,' ensure it accepts POST requests, and optionally enable header authentication with a secure key. The Validate Input node ensures the operation is one of: processJson, processBinary, processStatic, or processAll. Ensure sufficient server resources (memory, disk) for binary data handling in self-hosted setups.\n\nTesting and Deployment Steps: Test by sending a POST request to the Webhook URL (from the Webhook Trigger node) using Postman. Example JSON body: {'operation': 'processJson', 'data': {'message': 'Test'}} or {'operation': 'processBinary', 'data': {'text': 'Hello'}} with the authentication header if enabled. The 'Success Response' node returns a 200 status with processed data (JSON, binary info, or static data details), or 'Error Response' (400 status) for invalid operations. Monitor logs for errors like malformed JSON or insufficient memory for binary processing, and verify input formats if issues occur. Activate the workflow in n8n’s interface for deployment. Validate outputs to confirm the operation type and processed data (e.g., JSON structure, binary metadata, or static data counts) match the request
