A well-tested library that lets you get trophy, user, and game data from the PlayStation Network.

  options: Partial<AllCallOptions> = {},
  args: Record<string, string | number> = {}

  // eslint-disable-next-line @typescript-eslint/no-unused-vars -- This is an intentional pick.
  const { headerOverrides, ...pickedOptions } = options;

  const concatenated = `${baseUrl}/${endpointUrl}`;
  const withoutDoubleSlashes = concatenated.replace(/([^:]\/)\/+/g, "$1");

    }
  }

  const queryString = new URLSearchParams(queryParamValues).toString();
