Support more specific error responses for enhanced security validation failures
June 10th, 2026
On July 10th, when a payment method tokenization request fails enhanced security validation, Spreedly will return a specific error key and message instead of the generic errors.invalid_enhanced_authentication_params. The new keys are:
errors.missing_tokenization_parameterserrors.invalid_tokenization_timestamperrors.expired_tokenization_certificateerrors.invalid_tokenization_certificateerrors.invalid_tokenization_signatureerrors.replayed_tokenization_nonceerrors.unknown_tokenization_validation_failure
