  title: Trulioo Document Verify And Download Evidence Image
  summary: Verify an identity document, then download a captured evidence image from the transaction.
  description: >-
    After an identity document verification completes, the captured document and
    selfie images are retained as evidence on the transaction. This workflow runs
    a document verification and then downloads a named evidence image (e.g. the
    front of the ID or the selfie) from the resulting transaction record. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
