# Check the Reliability endpoint deprecated

**Date:** April 9, 2026
**Type:** 

The [Confirm Bank Account endpoint](https://developer.cdq.com/apis/bankaccount-data-api/api-v2/bank-account-verification/paths/~1bankaccounts~1confirm/get) in Bank Account Data API v1 is being retired as part of our ongoing effort to continuously improve the bank account verification service. It has been superseded by the updated [Confirm Reliability endpoint](https://developer.cdq.com/apis/bankaccount-data-api/api-v2/bank-account-verification/paths/~1v2~1bankaccounts~1confirm/post) in Bank Account Data API v2, which provides expanded functionality including fraud case detection against the CDQ Blacklist alongside the existing whitelist trust score check. The new endpoint also introduces a structured JSON request body in place of query parameters, enabling a more robust and extensible integration.

## Retirement schedule

| Item | End of Support | End of Life |
|  --- | --- | --- |
| [Confirm Bank Account](https://developer.cdq.com/apis/bankaccount-data-api/api-v2/bank-account-verification/paths/~1bankaccounts~1confirm/get) (Bank Account Data API v1) | April 30, 2026 | October 30, 2026 |


After the **End of Support** date, no further security patches or bug fixes will be applied to the retired endpoint. 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

Replace calls to the [Confirm Bank Account endpoint](https://developer.cdq.com/apis/bankaccount-data-api/api-v2/bank-account-verification/paths/~1bankaccounts~1confirm/get) (v1) with the [Confirm Reliability endpoint](https://developer.cdq.com/apis/bankaccount-data-api/api-v2/bank-account-verification/paths/~1v2~1bankaccounts~1confirm/post) in Bank Account Data API v2. The new endpoint accepts a JSON request body instead of query parameters — pass the bank account identifiers inside a `bankAccount` object. Both IBAN-based and BIC/national account number-based identification are supported. Refer to the Bank Account Data API quickstart for the full request structure and examples.
