  summary: Create a collection, then create a webhook that runs it on incoming POSTs.
  description: >-
    Webhooks let external systems trigger a Postman collection run by sending an
    HTTP POST to a generated URL. This workflow creates a collection and then
    creates a webhook bound to it, capturing the generated webhook URL. Each
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI descriptions.
