​
Response Components

  1. status
    • Type: string
    • Values: OK (for successful responses) or an error type.
    • Example: "status": "OK"
  2. placements
    • Type: array
    • Description: An array of placement objects, each representing a specific ad placement on the page.
  3. page-uid
    • Type: string
    • Description: A GUID value identifier for each ad request.
    • Example: "page-uid": "7f0b8394-f87f-438f-bf4a-b2aeae1e3144"

​
Placement Object

Each placement object contains the placement Name as the single key for the object, e.g., viewCategory_API_desktop-inGrid. Inside each placement, we have:
  • Format
    • Type: string
    • Description: The type of ad, e.g., sponsored_products.
  • Products
    • Type: array
    • Description: An array of product objects.
  • Rendering
    • Type: string
    • Description: rendering details used for commerce display ads.
  • OnLoadBeacon
    • Type: string
    • Description: URL to be called when the whole placement is loaded.
    • Example: "OnLoadBeacon": "//b.us5.us.criteo.com/rm?fid=1205&hl_qs_cmp=&ev=4&criteopartnerid=108341&action=page&origc=A&pid=a0396133-15e5-4d8d-a0d7-7e636a0c9629&rn=96592&rm_e=abc123def4"

    • Description: URL to be called when the placement is viewed according to IAB guidelines.
    • Example: "OnViewBeacon": "//b.us5.us.criteo.com/rm?rm_e=abc123def4&ev=4"
  • OnClickBeacon
    • Type: string
    • Description: URL to be called when the placement is clicked. This is only used on commerce display ads, and it is typically triggered on clicks on the ad’s image as opposed to the product inside the ad.
    • Example: "OnClickBeacon": ""

​
Product Object

Each product object contains:
  • ProductId

  • OnWishlistBeacon
    • Type: string
    • Description: URL to be called when the product is added to the wishlist.
    • Example: "OnWishlistBeacon": "//b.us5.us.criteo.com/rm?rm_e=abc123def4&ev=4"

​
Monitoring the Auction Latency

The API response includes a Server-Timing header which indicates how many milliseconds the auction took to run. This can be used to monitor server latency and break the auction part from the full round trip between ad request and response.

​
Sample Request

curl -I "https://d.eu.criteo.com/delivery/retailmedia?criteo-partner-id=108341&retailer-visitor-id=456&customer-id=789&page-id=viewSearchResultApiDesktop&event-type=viewSearchResult&keywords=drink"

​
Response headers

HTTP/2 405 
date: Mon, 31 Mar 2025 14:19:56 GMT
server: Kestrel
access-control-expose-headers: Server-Timing
allow: GET
timing-allow-origin: *
server-timing: total;dur=1.2
strict-transport-security: max-age=31536000; preload;
In this example, the auction took 1.2 ms to run.

​
Product Array Verbosity Levels

Criteo supports two verbosity levels:
  • Minimum verbosity
    • Contains: ProductId, ParentSKU, beacons (OnLoadBeacon, OnViewBeacon, OnClickBeacon, OnBasketChangeBeacon, OnWishlistBeacon).
  • Full verbosity
    • Contains: All information from minimum verbosity plus additional details necessary to render the ad. All details are reflected from the product feed parameters.
Here is an example of a product object in full verbosity:

   "ProductName": "Product 16823",
   "ProductId": "16823",
   "ProductPage": "//b.us5.us.criteo.com/rm?dest=https%3a%2f%2ftilt-dummy-retailer.preprod.crto.in%2fpdp%2f%3fid%3d16823&sig=1-OxTyYEct2uXeVQw334Q7rhli3hjJSfL-t1eGN0YS-2A&rm_e=uel8HURJNMmUz12YtgzGAeSR-psXmQFLCnVtykXin5b5LlMOlwR9k1w4PnZ93nTwLSLRM8h_OVK_nPLkK84uY4wBFzIx8x9AxzThTINQ0fpTsiJt_tTMuHfyLNG47gWwg5f6dDZons5DMKmZEjVsNAGmsiLF7YpZb8lFAmqaKyx8B9qIZJatI7ApL7VCCO1NAv6bvz6EQ1tvPDcZc6kY7cw5uLT5egrtd3Nupj5vJ6R_PQy-jmS5rEcmViA_Yf5AcP-teeD_wY3x59nlISoZP-sLqIksWuUr0QRfF8Z6DnR3ZQzunCi5PONmLtM1zSgOCHFj4fyf-A3GbbLe1kJdNyQtS7PZAsR04DDYAg5QEMzJoGcZGS7VVH_h5bLnF4dArQuIUamTFePufu7tmYxQvA&ev=4",

 }
The default verbosity level can be set up by your technical account manager, but it can be changed at anytime using the verbosity parameter in the API calls with values min or full. See the API parameters page for more details.

​
Beacon Endpoints

The beacon endpoint will point to different data centers determined by an automatic load balancer. This will typically be reflected on its subdomain.
  • Format: b.[datacenter].[region].criteo.com/rm
  • Examples:
    • Europe: b.fr3.eu.criteo.com/rm?rm_e=[unique-token]&ev=4
    • Americas: b.us5.us.criteo.com/rm?rm_e=[unique-token]&ev=4

​
API Error Responses

If an API call is malformed or unable to send a valid response, the API will return a 200 HTTP status with an error message. For requests with incorrect or missing parameters, the response will include 'status': 'Error' with an array of 'errors'.

​
Example Error Response

{
  "status": "Error",
  "placements": [],
  "errors": [
    "Missing required param page-id",
    "Missing required param event-type",
    "Missing required param criteo-partner-id",
    "Could not convert parameter criteo-partner-id to an integer",
    "Could not determine a valid event type from the event-type parameter"
  ],
  "page-uid": null
}
The following list, while not exhaustive, covers most error messages you may encounter. Tracking those messages is recommended to identify potential implementation errors.
