  title: SendGrid List Add Contacts and Count
  summary: Create a list, upsert contacts into it, and branch on the list's contact count.
  description: >-
    Builds a contacts list, populates it, and inspects its size. The workflow
    creates a new marketing list, upserts contacts into that list (an
    asynchronous operation that returns a 202 with a job_id), and then reads the
    list's contact count, branching on whether the list is empty or already has
    contacts so the caller can decide whether to poll again for the upsert job.
    Each step inlines its request and bearer token so the flow can be read and
    run without the OpenAPI files.
