Sponsored Products Line Items

We recommend using Line Item Core for new integrations. The unified POST /line-items endpoint is the new standard for creating and updating line items across campaign types. Sponsored Products support is not yet available in Line Item Core — the endpoints on this page remain the supported path for SP campaigns in the meantime.

Keyword Targeting

Criteo’s API lets you control search placements based on keywords shoppers use. You can specify keywords to target or avoid, and set bids on the most relevant terms.

Negative Keywords

Negative keyword targeting lets you exclude keywords from triggering your ads. Two match types are supported:

Match Type	Negative Keyword	Ads Won’t Show For	Ads May Show For
Broad match	Men’s shoes	Men shoes, Blue men’s shoes, Men’s shoe size 9	Shoes, Boy’s shoes, Men’s basketball shoes
Exact match	Men’s shoes	Men’s shoes, Mens shoes, Mens shoe	Shoes, Blue men’s shoes, Mens shoe size 9

Broad match is a subset of exact match — keywords set as broad are treated as both broad and exact matches.

Submitted Keywords

Submitted (positive) keywords target shoppers whose search phrases closely match what you specify, using PositiveExactMatch. You can also prune matches using NegativeExactMatch and NegativeBroadMatch. When you submit a positive keyword it enters a pending state. Criteo’s system will automatically approve or reject it:

Already mapped in the keyword model → approved automatically
Contains a competitor brand name → rejected and deactivated
Cannot be validated automatically → sent to manual review

Keyword Bidding

Keyword bidding gives granular control over spend by allowing specific bids per keyword. The bid must respect the line item’s minimum CPC. If a maximum CPC is set on the line item, it is always enforced even if a keyword bid exceeds it. Bids only take effect once a keyword is approved.

Update a specific Onsite Sponsored Products Line Item

This endpoint updates the specified Onsite Sponsored Products line item. In this example, we are:

renaming the line item and start date, to be scheduled to deliver during Q4.
enabling auto daily pacing by setting a monthly pace simultaneously. Note that with auto daily pacing enabled, daily pacing is automatically calculated and overwrites its previous value, if any.
modifying the day scheduling to deliver ads during extended weekend evenings only, i.e., Fridays, Saturdays and Sundays from 18h until 0h (local time)

Also, note the draft state of the line item because products to be promoted have not yet been added. Sample Request
