Call from Apata to an external system to verify whether the OTP provided by the cardholder is correct.

Configuration "delegateFormat": "V2.0" in your OTP challenge method to make use of this format.

API Backwards Compatibility: Apata may introduce non-breaking changes to API requests and responses, including the addition of new fields. To ensure continued compatibility, please design API validation logic to tolerate and gracefully handle any extra fields that may be included in the payload.
