Processing API

• Create transactions — Submit documents for processing with a specific skill
• Manage files — Upload, edit, and organize document images
• Track status — Monitor transaction progress and handle errors
• Retrieve results — Download extracted data in JSON or XML format
• Manage catalogs — Work with data catalogs and lookup tables

​

Common Workflows

• Processing Documents with a Single API Call — Process documents with a single request that handles upload, processing, and result retrieval automatically.
• Processing Documents with Separate API Calls — Use separate API calls for fine-grained control over document upload, processing, and result retrieval.
• Integrating Manual Review — Integrate manual review into your workflow for documents requiring human verification.

​

Reporting API

• Business metrics — Transaction volumes, processing times, and throughput
• Quality analytics — Extraction accuracy and confidence scores
• Field-level data — Detailed extraction results for analysis

​

Output Formats

• JSON Output — Hierarchical data with full extraction details and confidence scores
• XML Output — Structured markup for systems requiring XML integration

Developer Resources

• Getting Started with the Vantage API — Start here — make your first call, authenticate, and choose a processing scenario
• Postman Collection — Ready-to-use API collection for testing and exploration

​

Rate Limits & Best Practices

• Batch operations — Use batch endpoints when processing multiple records (up to 5,000 catalog records per request)
• Polling — When checking transaction status, use reasonable intervals (5-10 seconds)
• Error handling — Implement retry logic with exponential backoff for transient errors
