  title: Adobe Generate a Document From a Template
  summary: Upload a Word template, merge JSON data into it, poll the job, and fetch the generated document.
  description: >-
    Drives the Adobe PDF Services asynchronous document-generation pipeline
    that merges a Word (DOCX) template with JSON data to produce a PDF or DOCX.
    The workflow registers the template by requesting a pre-signed upload URI
    and asset ID, submits a generateDocument job with the merge data and output
    format, polls the job until it reports done, and resolves a download URI
    for the generated document. Each step spells out its request inline. The
    polling job identifier is supplied as a workflow input because the submit
    response exposes only an opaque Location header.
