[null,null,["最后更新时间 (UTC):2025-02-25。"],[],["The Display & Video 360 API v4 (beta) allows line item duplication via a POST request to `https://displayvideo.googleapis.com/v4/advertisers/{advertiserId}/lineItems/{lineItemId}:duplicate`. It requires `advertiserId` and `lineItemId` path parameters. The request body must include a `targetDisplayName` for the new item. The successful response provides a `duplicateLineItemId`. YouTube & Partners line items cannot be managed and high latency is common. The authorization scope needed is `https://www.googleapis.com/auth/display-video`.\n"]]
