  title: Adobe Delete Pages From a PDF
  summary: Upload a PDF, delete a page range, poll the job, and fetch the trimmed result.
  description: >-
    Drives the Adobe PDF Services asynchronous delete-pages pipeline that
    removes a range of pages from a PDF. The workflow registers the source PDF
    by requesting a pre-signed upload URI and asset ID, submits a deletePages
    job describing the page range to remove, polls the job until it reports
    done, and resolves a download URI for the trimmed 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.
