  title: ThingSpeak Post Status and Read Status Updates
  summary: Write an entry carrying a status message, then read the channel's status update feed.
  description: >-
    A flow for annotating a channel timeline with human-readable status messages.
    It writes an entry that carries a status string alongside an optional field
    value, then reads the channel's status update feed to confirm the message was
    recorded. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
