# Legacy Validation deprecated

**Date:** April 13, 2026
**Type:** 

Two endpoints in the Data Validation API are being retired as part of our transition to a more capable and unified validation service. The Validate Business Partner endpoint in v1 is superseded by its v2 counterpart, which extends defect detection to identifiers and legal forms and provides a more detailed response structure. The [Start Record Validation Job endpoint](https://developer.cdq.com/apis/data-validation-api/api-v3/batch-validation/paths/~1v2~1recordvalidationjobs/post) is being discontinued entirely — continuous validation of data at scale is now handled by Data Quality Monitors on Data Mirrors, which offer real-time monitoring without the overhead of managing asynchronous validation jobs.

## Retirement schedule

| Item | End of Support | End of Life |
|  --- | --- | --- |
| Validate Business Partner (Data Validation API v1) | April 30, 2026 | May 31, 2026 |
| [Start Record Validation Job](https://developer.cdq.com/apis/data-validation-api/api-v3/batch-validation/paths/~1v2~1recordvalidationjobs/post) (Data Validation API v2) | April 30, 2026 | May 31, 2026 |


After the **End of Support** date, no further security patches or bug fixes will be applied to these endpoints. It is highly recommended to migrate before the `end-of-life` date to avoid exposure to unpatched vulnerabilities and service disruption.

## What you need to do

**Migrating from Validate Business Partner (v1)**

Replace calls to the v1 Validate Business Partner endpoint with the v2 version. The request body structure remains the same. Refer to the Data Validation API quickstart for the full request details.

**Migrating from Start Record Validation Job**

Batch record validation as an asynchronous job is no longer supported. Instead, upload your data to a Data Mirror and activate Data Quality Monitoring to continuously validate business partner records and receive defect notifications in real time. See the migration guide linked below.
