  title: SendGrid Single Send Stats
  summary: List Single Sends, branch on whether any exist, and pull aggregate stats for one.
  description: >-
    A reporting flow over Single Send performance. The workflow lists the
    account's Single Sends, branches on whether any were returned, and when at
    least one exists retrieves the aggregate stats for the supplied Single Send
    ID. Both calls return 200. Each step inlines its request and bearer token so
    the flow can be read and run without consulting the OpenAPI files.
