  title: WhatsApp Find and Update Message Template
  summary: Locate a template by name and edit its body, when it is in an editable state.
  description: >-
    Only APPROVED or PAUSED templates can be edited, and edits re-trigger Meta's
    approval process. This workflow lists templates on a WhatsApp Business
    Account filtered by name, branches on whether the matched template is in an
    editable status, and when it is submits an update to its BODY component
    against the template ID. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
