  title: Salesforce Marketing Cloud Upsert and Read Data Extension Rows
  summary: Authenticate, upsert rows into a Data Extension, then read the rows back.
  description: >-
    A Data Extension data-loading pattern for Marketing Cloud. The workflow
    obtains an OAuth 2.0 access token, inserts (upserting on primary key) a set
    of rows into a Data Extension identified by its external key, then reads a
    page of rows back from the same Data Extension to confirm the data landed.
    The Marketing Cloud REST description does not expose an operation to create a
    Data Extension, so this workflow targets an existing Data Extension by key
    and focuses on the row upsert-then-read cycle. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
