n8n-nodes-docuprox

An n8n custom node for integrating with the DocuProx API to process documents using AI-powered document processing templates.

Description

This n8n node allows you to process documents by providing a template ID and an image (either as a binary file upload or base64 encoded string). The node communicates with the DocuProx API to extract structured data from documents based on predefined templates.

Installation

1. Clone or download this repository
2. Navigate to the project directory
3. Install dependencies:
``bash
npm install
`
4. Build the project:
`bash
npm run build
`
5. Copy the dist folder to your n8n custom nodes directory
6. Restart n8n

Usage

1. Add the "DocuProx" node to your n8n workflow
2. Configure your DocuProx API credentials (see Configuration section)
3. Set the Template ID for the document processing template you want to use
4. Choose your image source:
- Upload Image File: Provide the binary property name containing the image file
- Base64 String: Directly input the base64 encoded image data
5. Execute the workflow

The node will return the processed document data from the DocuProx API.
