  title: UiPath Digitize, Classify, and Extract a Document
  summary: Run the full document understanding pipeline with polling for async results.
  description: >-
    The end-to-end Document Understanding pipeline. The workflow digitizes a
    base64-encoded document to obtain a document ID, starts an asynchronous
    classification and polls until it completes, then starts an asynchronous
    extraction against the digitized document and polls until the extracted
    fields are ready. Poll loops repeat while the async job status is NotStarted
    or Running. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.

  summary: Digitize a document, then classify and extract it with async polling.

    Digitizes a document to obtain a document ID, runs async classification with
    polling, then runs async extraction with polling against the same document.
