We’re introducing new Partner API features for programmatic access to data from our AI Business Solutions & Security Insights in Partner Center. This brings parity with the latest insights available in Partner Center, while modernizing our authentication model. As part of this evolution, we’re deprecating the legacy endpoint and its authentication mechanism to ensure better performance, security, and consistency. Review the details below to see if this change affects you and what updates your integrations need before the legacy API is deprecated.
The API, at a glance
The Partner API is a production grade interface that gives Microsoft partners programmatic access to the complete dataset behind the AI Business Solutions & Security reports in Partner Center. It brings automated, right time actions and embedded intelligence into the digital workspaces where partner sales and customer success teams work every day. Sellers get the next best actions with their accounts, managers see pipeline risk and momentum, and customer success teams can proactively drive adoption with the right customer data and incentives at their fingertips. With a single, standardized surface, partners can ingest Microsoft customer insights such as usage signals, upsell propensity, incentive eligibility, referral opportunities, and more - directly into Power BI dashboards, agentic integrations, and CRM pipelines.
What’s new
- Broader data coverage: Access the latest usage, propensity, incentive eligibility and more, surfaced in the AI Business Solutions & Security Insights report.
- Extensive documentation: Learn documentation
- Modernized access model: A streamlined authentication mechanism improves security and compliance, aligning with Microsoft’s current standards.
- Performance and resilience improvements: Lower latency and improved throttling behavior to support production grade workloads.
Legacy API sunset
If your organization is currently using the legacy AI Business Solutions & Security Insights Partner API or the FastTrack API with certificate-based authentication, you must move to the new domain and modern authentication. There are no schema changes required.
Action required: Migrate by January 28, 2026
Not sure if you’re using the legacy API? Please check if any of your integrations are calling partner.fttoolingapi.com domains, for example: https://uat.partner.fttoolingapi.microsoft.com/ftop/v1.3/api/ or
https://prod.partner.fttoolingapi.microsoft.com/ftop/v1.3/api/.
What’s changing
- Authentication: Manual certificate-based sign-in >> Modern OAuth 2.0-based sign-in
- Endpoints
The new authentication method and endpoints are available now, so you can start planning and executing your migration.
