Sellers only need to provide basic campaign information, such as the user-defined campaign name, the start date (and optionally the end date) of the campaign, the daily budget amount of the campaign, and the eBay marketplace where the campaign will be hosted. The seller must also identify the items they want to place in the campaign by adding the listing id of each item in the listingIds array of the request.

Using the provided listingIds, eBay creates ad groups for the campaign and organizes the listings into the appropriate ad group. eBay then adds keywords to each ad group and assigns each keyword a suggested bid.

By default, campaigns created using setupQuickCampaign utilize a FIXED keyword bidding strategy which means that a seller manually assigns and adjusts keyword bids for their CPC campaign.

Alternatively, once the campaign has been created, sellers may opt to utilize a DYNAMIC bidding strategy which means that eBay will manage a campaign's keyword bids and automatically update them daily to the suggested bid.

For additional information about FIXED and DYNAMIC bidding strategies, refer to updateBiddingStrategy.
