  title: WhatsApp Create and Retrieve QR Code
  summary: Create a click-to-chat QR code and read back its deep link and image URLs.
  description: >-
    Click-to-chat QR codes let a business put a scannable code on print or
    digital media that opens a WhatsApp conversation pre-filled with a message.
    This workflow creates a QR code with a prefilled message for a phone number
    and then reads the created QR code back by its identifier to retrieve its
    deep link and hosted image URLs. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
