Tealium October 2026 Updates: OpenAI, Google Ads & DV360 Integrations

In October 2026, Tealium introduced updates to its integrations with ChatGPT Ads, Google Ads, and Display & Video 360. The main changes involved conversion data transmission through server-side APIs, Customer Match audience management, and data exchange between advertising platforms and the Customer Data Platform (CDP).

What's New in October 2026

October 6 — Integration With ChatGPT Ads Measurement Pixel and Conversions API

Tealium announced support for client-side and server-side conversion tracking for ChatGPT Ads. Measurement Pixel allows events to be sent directly from the browser through Tealium iQ, while Conversions API sends events from the server side.

Advertisers can transmit purchase, registration, and other conversion data using their existing Tealium tracking infrastructure. Supported capabilities include event mapping, transaction parameter transmission, user consent management, and deduplication of browser and server events using Event ID.

October 7 — Advanced Conversion Matching for ChatGPT Ads Pixel

Advanced conversion matching parameters were added to the ChatGPT Ads Measurement Pixel tag template. They enable configuration of additional identifiers to improve the matching of conversion events with ad interactions.

To use the new parameters, advertisers must update the tag template in Tealium iQ.

October 16 — Fix for User Consent Transmission in ChatGPT Ads Pixel

Tealium updated its handling of consent parameters so that consent values are passed to the OpenAI SDK in Boolean format. This change resolves an issue with the interpretation of consent settings when events are transmitted.

Applying the fix also requires updating the tag template.

October 28 — OpenAI Events Connector Expansion

Tealium's server-side connector gained the ability to send attribution records for individual events provided by advertising measurement partners to OpenAI. The integration uses the existing Pixel ID and Conversions API key.

The new capability is designed to exchange attribution data between measurement systems and OpenAI's advertising platform.

October 28 — New Google Ads Data Manager Conversions Connector

Tealium added a separate server-side connector for sending conversion events to Google Ads through the Google Data Manager API. It enables data to be transmitted from Customer Data Hub directly into Google Ads infrastructure without relying solely on a browser-based tag.

The connector expands the options for transmitting first-party conversion data to measure advertising performance.

October 28 — Google Ads Customer Match Update

Tealium updated how diagnostic information is retrieved in Connector Insights for Google Ads Customer Match actions that use the Data Manager API. Relevant connector metrics are now requested through the Google Data Manager API.

This change concerns audience synchronization monitoring and data processing, not a new targeting method.

October 28 — Google DV360 Customer Match Expansion

The connector for transmitting Customer Match audiences to Display & Video 360 received additional segment settings: audience description, integration code, and user membership duration expressed as a whole number of days.

These settings provide more precise control over audience metadata when audiences are created and updated.

October 28 — DV360 Statistics Update Through Data Manager API

For DV360 Customer Match actions using the Google Data Manager API, Tealium switched Connector Insights to retrieve data through that API.

The update concerns diagnostic information about audience synchronization, not advertising campaign performance statistics.

What Is Tealium?

Tealium is a Customer Data Platform (CDP) that combines event collection, tag management, customer profile creation, and data transmission to advertising and analytics systems.

Tealium iQ manages client-side tags, EventStream handles server-side event processing, and AudienceStream unifies customer data and builds audiences. The platform enables companies to centrally manage conversion data transmission, user consent settings, and first-party data for Google Ads, Meta Ads, OpenAI, and other advertising systems.

Important: Tealium's integration with OpenAI model APIs for AI-based processing of customer data existed before October. The October changes covered here primarily concern ChatGPT Ads measurement.
