marketing APIv1.10.0


This method works with listings that are managed with the Inventory API.

The method:

  • Creates an ad for the specified listing.
  • Sets the bid percentage (also known as the "ad rate") for the ad.
  • Associates the ad with the specified campaign.

To create an ad for a listing, specify its inventoryReferenceId and inventoryReferenceType, plus the bidPercentage for the ad in the payload of the request. Specify the campaign to associate the ad with using the campaign_id path parameter.

In the Inventory API, an inventory reference ID is either a seller-defined SKU value or an inventoryItemGroupKey (a seller-defined ID for a multiple-variation listing).

Each campaign can have ads for a maximum of 50,000 items, and each item in a multiple-variation listing is considered as an individual item.

Use createCampaign to create a new campaign and use getCampaigns to get a list of existing campaigns.

Input container/fieldTypeDescription
bidPercentagestringThe user-defined bid percentage (also known as the ad rate) sets the level that eBay increases the visibility of a listing across the eBay buyer flows. The higher the bidPercentage value, the more eBay promotes the listing.

The value specified here is also used to calculate the Promoted Listings fee. This percentage value is multiplied by the final sales price to determine the fee.

The Promoted Listings fee is determined at the time the transaction completes and the seller is assessed the fee only when an item sells through a Promoted Listings ad campaign.

bidPercentage is a single precision value that is guided by the following rules:
  • These values are valid:
       1,    1.0,    4.1,
       5.0,    5.5, ...
  • These values are not valid:
       0.01,    10.75,    99.99,
       and so on.

If a bid percentage is not provided for an ad, eBay uses the default bid percentage of the associated campaign.

Minimum value: 1.0
Maximum value: 100.0
