  title: WhatsApp Send Message then React to It
  summary: Send a text message and then apply an emoji reaction to that same message.
  description: >-
    Reactions add a lightweight emoji acknowledgement to a specific message.
    This workflow sends a text message to a recipient, captures the returned
    message ID, and then sends a reaction message that applies an emoji to that
    exact message. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
