  title: Adobe Split a PDF
  summary: Upload a PDF, split it by page count into multiple files, poll the job, and fetch the result.
  description: >-
    Drives the Adobe PDF Services asynchronous split pipeline that divides a
    PDF into multiple smaller files by page count, page ranges, or file count.
    The workflow registers the source PDF by requesting a pre-signed upload URI
    and asset ID, submits a splitPDF job with the chosen page count, polls the
    job until it reports done, and resolves a download URI for the split
    output. 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.
