This release introduces major improvements across onboarding, data governance, AI integrations, predictive capabilities, and server-side connectors.


MCP integration documentation

New documentation is available to help customers and partners connect Eulerian to LLMs and AI assistants through the Model Context Protocol.
The documentation is designed to support MCP integrations across all compatible LLM providers.


Agent2Agent protocol support

Eulerian now supports the Agent2Agent protocol, facilitating standardized communication and collaboration between AI agents.


Guided onboarding for non-Enterprise accounts

A new guided onboarding experience is now available for non-Enterprise accounts.
Interactive tutorials help users discover the platform and complete their initial configuration. The onboarding process is connected to Pipedrive to automate CRM follow-up and improve visibility into account activation.


Site Section Management

Eulerian now supports site section management.
Site sections can be used as an additional data segmentation level, enabling visits, conversions, and other metrics to be deduplicated and analyzed independently for each section of a website.


Hybrid authentication

Eulerian can now manage multiple authentication methods depending on the user account configuration.
The following authentication methods are supported:
  • password-mfa-sms: password authentication combined with an MFA code sent by SMS
  • sso-internal: Single Sign-On authentication based on an internal Eulerian setup
  • password-totp: password authentication combined with a one-time code delivered by email or generated through an authenticator application
  • password: password-only authentication
This provides greater flexibility for managing different customer security requirements within the same platform.


OAuth support for API access

Eulerian APIs now support OAuth-based authentication using Dynamic Client Registration and Client-Initiated Metadata Documents.
This enables more secure and standardized API access for:
  • Web-based MCP implementations
  • Third-party integrations
  • AI agents and external applications


Use API documentation with AI

A new Use with AI button has been added to the API documentation.
Users can now export the API documentation directly to their preferred LLM, making it easier to:
  • Explore available endpoints
  • Generate integration examples
  • Build API requests
  • Troubleshoot implementations
  • Accelerate the development of AI agents and third-party integrations


Connectors

OpenAI CAPI

A new OpenAI CAPI connector is now available, enabling Eulerian data to be shared with OpenAI-supported activation and measurement workflows.


Meta CAPI

The Meta Conversions API connector now supports the following additional fields:
  • ltv_predicted
  • customer_segmentation
These fields can be used to enrich conversion signals with predicted customer value and audience segmentation data.


The Trade Desk — Eulerian Partner Connect

A new The Trade Desk integration is now available through Eulerian Partner Connect.
The connector collects third-party media data, including:
  • Clicks
  • Impressions
  • Media costs
This data can then be integrated into Eulerian reporting, attribution, and media performance analysis.


Meta — fine-grained event deduplication

Meta integrations now provide more granular deduplication between events collected through a Tag Management System and events sent server-side.
This improvement reduces duplicate conversions while preserving valid events across hybrid client-side and server-side implementations.


Google Ad Manager PPID cookie matching

Eulerian now supports cookie matching based on Google Ad Manager Publisher Provided Identifiers.
This provides an additional mechanism for reconciling publisher and Eulerian identities in compatible activation and measurement use cases.


Other improvements

New alias management process

The alias management process has been updated to improve reliability and resolve issues affecting campaign retrieval in ReportCenter.

AppsFlyer real-time data collection

The AppsFlyer integration has been updated to improve the collection and processing of data in real time.

Sales and estimates cancellation

The PRAGMA mechanism used when canceling sales or estimates now supports both device and subkey2 dimensions.
This prevents reporting discrepancies when canceled transactions are analyzed using these filters.
