  description: >-
    Postman Webhooks enable you to receive incoming HTTP POST requests that
    trigger collection runs. When an external system sends a POST request to
    a Postman webhook URL, the webhook triggers a collection run and makes the
    incoming payload available as variables during the run. This provides a way
    to integrate Postman with CI/CD pipelines, monitoring systems, and other
    external services that need to trigger automated API testing workflows.

    Postman also supports custom webhooks for monitor notifications, which
    deliver alerts about monitor run failures and errors to your configured
    endpoints.

    protocol: https
    description: >-
      Your webhook receiver endpoint. External systems send POST requests to
      the Postman-generated webhook URL to trigger collection runs. The webhook
      URL is generated when you create a webhook via the Postman API.
    variables:
      webhookUrl:
        description: >-
          The webhook URL generated by Postman when the webhook is created.
          This URL is unique to each webhook and includes authentication
          built into the URL path.
  monitor-notification-receiver:
    url: '{notificationUrl}'
    protocol: https
    description: >-
      Your notification endpoint that receives monitor run results. Configure
      this URL in your Postman monitor's notification settings or through
      integrations.
    variables:
      notificationUrl:
        description: >-
          The URL configured to receive monitor notification webhooks.
channels:
  /webhook/trigger:
    description: >-
      Channel for incoming webhook triggers that initiate collection runs.
      When an external system sends a POST request to the webhook URL, Postman
      triggers the associated collection run and passes the request payload
      as variables available during the run.

        External systems send POST requests with JSON payloads to this
        channel. The payload data becomes available as variables in the
        collection being run, accessible via pm.variables.get() in
        pre-request and test scripts.
