# Marketing Solutions API Changelog

Release notes and announcements for the Criteo Marketing Solutions API. Versions are released twice a year, in January and July.

<Update label="2026.07 Version" tags={["New releases"]}>
  ## API Versioning Policy Update

  Starting with this release, the Criteo Marketing Solutions API moves to a cadence of **two versions per year**, released in January and July. We are also introducing a new **three-tier release model** — Experimental, Release Candidate, and Stable — replacing the previous two-tier system (Preview and Stable). Find out what this means for your integration in our [Versioning Policy](/criteo-apis/docs/versioning-policy) guide.

  ## Product Boost

  Five new endpoints are available to manage Product Boost configurations, letting you control which products are featured in your ads at the ad and dataset level. See the [API Reference](/marketing-solutions/reference/fetch-boosted-ad-associations) for full details.

  | Verb     | Endpoint                                                          | Description                                     |
  | -------- | ----------------------------------------------------------------- | ----------------------------------------------- |
  | `GET`    | `/marketing-solutions/ads/{ad-id}/product-boost`                  | List Product Boost configurations for an ad     |
  | `GET`    | `/marketing-solutions/ads/{ad-id}/product-boost/{product-set-id}` | Get a specific Product Boost configuration      |
  | `POST`   | `/marketing-solutions/ads/{ad-id}/product-boost/{product-set-id}` | Create a Product Boost configuration            |
  | `DELETE` | `/marketing-solutions/ads/{ad-id}/product-boost/{product-set-id}` | Delete a Product Boost configuration            |
  | `GET`    | `/marketing-solutions/dataset/{dataset-id}/product-boost`         | List Product Boost configurations for a dataset |

  ## Ad-Sets — New Fields and Attribution Methods

  Two additions to all ad-set endpoints (`PATCH`, `POST`, search, and `GET`):

  * `budget.pacingBehavior` — controls how the budget is paced over the campaign flight.
  * Two new values for `attributionConfiguration.attributionMethod`: `googleAnalytics` and `sftp`.

  See the [API Reference](/marketing-solutions/reference/patch-ad-sets) for full details.
