# Retailer Integration Changelog

Release notes and announcements for the Criteo Retailer Integration documentation.

<Update label="Version 2026.01" tags={["New releases"]}>
  ## New Onsite Display Formats

  Five new formats have been released, replacing the Legacy Onsite Display ones. We strongly recommend using the new formats for any new integration, as the legacy ones will be progressively phased out.

  You can find the documentation for the new formats [here.](/retailer-integration/docs/onsite-display-new-formats)
</Update>

<Update label="Version 1.3 (Q3–Q4 2025)" tags={["New releases"]}>
  ## New Video Player Implementation (App: iOS)

  We have published a new, enhanced guide that introduces a ready-to-integrate video ad wrapper that handles VAST parsing, video playback, and Open Measurement SDK compatibility for viewability and verification. This guide helps retailers to easily render, track, and measure in-app Onsite Video ad placements with minimal code.

  You can view it [here](/retailer-integration/docs/video-player-implementation-ios-app).

  ## New Server-Side Beacons Guide

  In most cases, client-side beacons (from the browser or app) are the preferred and recommended method for tracking ad events. However, in cases where this is not possible — such as on the server side, inside a mobile app, or within privacy-constrained environments — a server-side beacon can be used as a fallback.

  You can view our dedicated guide [here](/retailer-integration/docs/server-side-beacons).

  ## Beacon SDK Update

  As the new BeaconSDK v5 launched, we updated our dedicated page with new features, a quick start section, and best practices.

  You can find the updated guide [here](/retailer-integration/docs/beacon-sdk).

  ## New Landing Page

  We have revamped our developer portal landing page to better showcase the Retailer Integration Documentation alongside our APIs for Retail Media and Performance Marketing.

  That's the page you see when going to [developers.criteo.com](/).
</Update>

<Update label="Version 1.2 (Q2–Q3 2025)" tags={["New releases"]}>
  ## New Video Format

  A new format is now available: the **Branding Video Standout**. This format combines a branded video with a branded image and a CTA. Learn more about it [on the dedicated page](/retailer-integration/docs/branding-video-standout).

  ## Commerce Video is Now in General Availability

  Commerce Video is no longer in beta. You can find the dedicated documentation [here](/retailer-integration/docs/commerce-video-integration).

  ## Update of the Feed Parameter Page

  We have adjusted the formatting of the [feed parameter page](/retailer-integration/docs/product-feed-parameters) for better readability. The Product Importer API documentation is now located in the Retail Media API documentation to avoid duplicates.

  ## New Implemented Examples

  Embedded examples of implemented ads are now available for [Flagship](/retailer-integration/docs/flagship#implementation-example), [Butterfly](/retailer-integration/docs/butterfly#implementation-example), [Branded Header](/retailer-integration/docs/branded-header#implementation-example), [Interactive Header](/retailer-integration/docs/interactive-header#implementation-example), and [Digital Shelf Talker](/retailer-integration/docs/digital-shelf-talker#implementation-example) at the end of each guide in the Ad rendering section.
</Update>

<Update label="Version 1.1 (Q1 2025)" tags={["New releases"]}>
  ## New Product Importer API Guides

  The Product Importer API enables users to upload, update, and manage product datasets on the Criteo platform. We have added an entire new section dedicated to the Product Importer API in our "Feed & Product Data" section, where you can now find:

  * [The list of product dataset parameters](/retailer-integration/docs/dataset-parameters) (for both onsite and offsite)
  * [Product dataset examples](/retailer-integration/docs/product-dataset-examples)

  ## New Google Ad Manager Section

  The GAM or Google Ad Manager is a comprehensive ad management platform that enables publishers to manage, sell, and optimize both direct and programmatic ad inventory across web, mobile, and app environments. Retailers already using GAM can now also integrate with Retail Media by adding custom creatives to their line items. Learn how by visiting the new [GAM guide](/retailer-integration/docs/gam-overview).

  ## Legacy vs. Universal Beacons

  We have worked on [clarifying the distinction between "legacy" and "universal/standard" beacons](/retailer-integration/docs/legacy-universal-beacons) in the Ad Tracking section. We strongly encourage all new integrations to use universal beacons. A [migration guide](/retailer-integration/docs/legacy-universal-beacons#migrating-from-legacy-to-universal-beacons) is also available.

  ## Integration Best Practices

  Integration best practices guides have been incorporated into each of the main sections of the documentation: [Product feed](/retailer-integration/docs/feed-best-practices), [Requesting Ads](/retailer-integration/docs/requesting-ads-best-practices), [Ad rendering](/retailer-integration/docs/ad-rendering-best-practices), and [Ad Tracking](/retailer-integration/docs/ad-tracking-best-practices).

  ## OneTag Offsite for Hybrid Apps

  We have added a complementary page to the main [OneTag for Retail Media Offsite page](/retailer-integration/docs/onetag-for-offsite) for hybrid apps, covering how to retrieve the advertising ID from Android and iOS and pass it to OneTag. A [Hybrid apps](/retailer-integration/docs/onetag-offsite-for-hybrid-apps) page has also been added.

  ## New Implementation Examples for Flagship & Butterfly

  New implementation examples are now available for [Flagship](/retailer-integration/docs/flagship#implementation-example) and [Butterfly](/retailer-integration/docs/butterfly#implementation-example), with code samples in HTML, CSS, and JavaScript.
