通过广告订单支付时，需要什么？

When paying for ads via an advertising order on LinkedIn, you need to have a LinkedIn Ads representative. This is because advertising orders are typically used by larger advertisers or agencies who work directly with LinkedIn account managers to manage their campaigns and billing. A credit card is a common payment method for self-serve campaigns but not for advertising orders. A minimum spend of $50,000 is not a universal requirement for all advertising orders; while some large deals might involve significant budgets, it's not a prerequisite for simply using an advertising order as a payment method.
