  title: WhatsApp Create Template then Send
  summary: Create a new message template and send it once it is available.
  description: >-
    Provisions a brand new message template on a WhatsApp Business Account and
    then attempts to send it. Because Meta must approve new templates before
    they can be delivered, the workflow branches on the create response status:
    when the template is already APPROVED it sends immediately, and otherwise it
    ends so the caller can wait for approval. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
