    </>}
    ```

    - `after` (string) — The ID _after_ which we'll retrieve more contacts (for pagination). This ID will _not_ be included in the returned list. Cannot be used with the `before` parameter.

    - `before` (string) — The ID _before_ which we'll retrieve more contacts (for pagination). This ID will _not_ be included in the returned list. Cannot be used with the `after` parameter.

      :::callout{intent="info"}
      You can only use either `after` or `before`
      parameter, not both. See our
      [pagination guide](/guides/api-reference-pagination) for more
      information.
