Getting Started with the Vantage API

Get started with the ABBYY Vantage REST API: make your first call, authenticate with OAuth 2.0, choose a processing scenario, and explore with Postman, Swagger, and the MCP server.

The Vantage API lets you integrate intelligent document processing into your application — submit documents, track transactions, and retrieve structured data. For a conceptual overview of the Processing and Reporting APIs, base URLs, and output formats, see API introduction.

Make your first call

The fastest way to see the API end to end is the quickstart. In about 10 minutes you authenticate, find a skill, upload a document, and download the extracted data as JSON.

Process via API

Step-by-step quickstart with cURL and Python examples — from your first request to structured results.

Authenticate

Every request must include an OAuth 2.0 access token in the Authorization header. Choose the flow that fits your integration:

Flow	Best for
Resource Owner Password Credentials	Server-to-server integrations
Authorization Code Flow	User-facing applications
Client Credentials	Machine-to-machine communication

For token endpoints and request examples, see Authentication.

Contact ABBYY to request a tenant. Once you have one, your admin can create user accounts and API clients in Administration > API clients.

Choose a processing scenario

Pick the approach that matches how much control you need over the document workflow:

Single API call

Create the transaction, upload the file, and start processing in one request. Best for a single file under 30 MB that needs no image editing.

Separate API calls

Use separate requests for fine-grained control over file upload, ordering, image edits, and processing.

Postman collection

Authorize with either OAuth 2.0 flow and call every Vantage API method, including the Business Process Reporting Warehouse. Published on the ABBYY Marketplace.

Swagger reference

Browse and try every endpoint interactively from the live API reference.

Vantage MCP server

Add the MCP server to Claude Code or VS Code Copilot for AI-assisted access to the docs while you code.
