Document Understanding Cloud APIs Example

This code snippet demonstrates how to digitize, classify, and extract documents using UiPath Document Understanding API's.

Official Documentation

UiPath Document Understanding offers standalone capabilities, allowing integration with external tools and systems through APIs. This release includes APIs for Discovery, Digitization, Classification, Extraction, and Validation. Please take a look at the Official Documentation.

Requirements

• Rust 1.74.1

Setup

1. Clone the repository to your local machine:

   git clone https://github.com/nvpnathan/RustyDU.git

2. Navigate to the project directory:

   cd RustyDU

3. Install the required dependencies:

   cargo build

4. Set up your environment variables by creating a .env file in the root directory and adding the following variables:

APP_ID=
APP_SECRET=
AUTH_URL=https://cloud.uipath.com/identity_/connect/token
BASE_URL=https://cloud.uipath.com/<Cloud Org>/<Cloud Tenant>/du_/api/framework/projects/
PROJECT_ID=00000000-0000-0000-0000-000000000000

Usage

Processing Documents

1. Place the documents you want to process in the specified folder (example_documents by default).

2. Run the main script cargo run to process the documents:

3. Monitor the console output for processing status and any errors.

4. Extracted results will be printed to the console and saved in CSV format in output_results folder.
