💻API Endpoints - Document Classification

Welcome to the Extracta.ai Document Classification API. This section guides you through all available endpoints designed to help you classify uploaded documents into user-defined types and optionally extract structured data from them.

Whether you're automating invoice routing, separating receipts from contracts, or identifying CVs, this API gives you precise control over classification and downstream processing.

What is Document Classification?

Document Classification is the process of automatically assigning a document to a predefined category — such as an Invoice, Receipt, or Purchase Order — based on its content.

You define the categories (called Document Types), provide keywords, and optionally link them to extraction templates. Once classified, the document can automatically be parsed for structured data.

🧩 Document Types & Auto-Extraction

In classification, you define documentTypes with:

• A name and description

• A list of uniqueWords to guide classification

• (Optionally) an extractionId to enable automatic structured data extraction if a match is found

Learn how to define these properly in the Document Types page.
