## Job-Based Processing

All document extractions in Taxo are processed as **jobs**. When you create an extraction request, the system:

1. Creates a unique job with a `publicId` (e.g., "JOB20250104123456789A")
2. Processes the extraction asynchronously in the background
3. Allows you to track progress and get results using the job's `publicId`

Each job represents a single extraction request for a specific taxpayer, information type, and time period.

## Workflow

<Steps>
  <Step title="Authentication">
    Get your API key from the dashboard and configure authentication
  </Step>

  <Step title="Create Extraction Job">
    Send SAT credentials and search filters. You receive a job `publicId`
  </Step>

  <Step title="Asynchronous Processing">
    The API validates credentials and extracts documents from SAT in the background
  </Step>

  <Step title="Job Monitoring">
    Query the job status using the `publicId` until it completes
  </Step>

  <Step title="Notification (Optional)">
    Receive a webhook when documents are ready
  </Step>

  <Step title="Download">
    Download individual documents using the job's `publicId`
  </Step>
</Steps>
