## Path parameters

## Request body

- UserList — Represents an Authorized Buyers user list. Authorized Buyers can create/update/list user lists. Once a user list is created in the system, Authorized Buyers can add users to the user list using the bulk uploader API. Alternatively, users can be added by hosting a tag on the advertiser's page.
  - `name` string — Output only. Name of the user list that must follow the pattern `buyers/{buyer}/userLists/{user_list}`, where `{buyer}` represents the account ID of the buyer who owns the user list. For a bidder accessing user lists on behalf of a child seat buyer, `{buyer}` represents the account ID of the child seat buyer. `{user_list}` is an int64 identifier assigned by Google to uniquely identify a user list.
  - `status` 'STATUS_UNSPECIFIED' | 'OPEN' | 'CLOSED' — Output only. The status of the user list. A new user list starts out as open.
  - `urlRestriction` UrlRestriction — Deprecated. This will be removed in October 2023. For more information, see the release notes: https://developers.google.com/authorized-buyers/apis/relnotes#real-time-bidding-api Represents the URL restriction (for the URL captured by the pixel callback) for a user list.
    - `url` string — Required. The URL to use for applying the restriction on the user list.

    - `startDate` Date — Represents a whole or partial calendar date, such as a birthday. The time of day and time zone are either specified elsewhere or are insignificant. The date is relative to the Gregorian Calendar. This can represent one of the following: * A full date, with non-zero year, month, and day values. * A month and day, with a zero year (for example, an anniversary). * A year on its own, with a zero month and a zero day. * A year and month, with a zero day (for example, a credit card expiration date). Related types: * google.type.TimeOfDay * google.type.DateTime * google.protobuf.Timestamp
      - `month` integer — Month of a year. Must be from 1 to 12, or 0 to specify a year without a month and day.
      - `day` integer — Day of a month. Must be from 1 to 31 and valid for the year and month, or 0 to specify a year by itself or a year and month where the day isn't significant.
      - `year` integer — Year of the date. Must be from 1 to 9999, or 0 to specify a date without a year.
