Processing Documents

FSCO provides APIs for creating and uploading documents. The typical workflow for processing documents is:

1. Create a document record using the API
2. Upload the document file
3. Receive webhook notifications as the document is processed

1. Create Document

   When you create a document, FSCO will:

   • Generate a unique document ID
   • Associate it with your specified template and collection
   • Return the document ID immediately
   • Return a webhook notification when the document is created

2. Upload Document File

   After uploading a file, FSCO will:

   • Validate and scan the file
   • Process it using the template’s AI model and prompts
   • Extract the requested data
   • Send webhook notifications at each stage

Webhook Events

The following webhook events are sent during document processing:

• document.created - Sent when the document record is created
• document.updated - Sent when the document record is updated
• ocr.started - Sent when document OCR processing is started
• ocr.completed - Sent when document OCR processing is completed
• ai.started - Sent when document AI processing begins
• document.error - Sent if any errors occur during processing

Each webhook includes the document ID and current status, allowing you to track the document’s progress through your system.

This guide covers both creating new documents and uploading existing document files.

Prerequisites

Before you begin, ensure you have:

• A valid FSCO API key
• Your application’s environment configured with the API key
• A template ID for document processing
• A collection ID for organizing documents

Important Notes

• Document files must be in a supported format (PDF, DOCX, etc.)
• The template ID must be valid and active
• The collection ID must exist in your organization
• Document processing is asynchronous and may take some time
• You can track document processing status through the document activity endpoint
