create3DSecure
Creates a new 3D Secure verification intent.
Returns a Triple whose first slot holds the created ThreeDSecureVerification on success. When the API returns a structured error (e.g., an existing intent conflict), the second slot is populated with a ThreeDSecureVerificationError and the first slot is null. A transport-level failure populates the third slot with a NetworkingError.
Return
A Triple of (ThreeDSecureVerification?, ThreeDSecureVerificationError?, NetworkingError?).
Parameters
The request payload containing the payment method to verify.
Creates a new 3D Secure verification intent and delivers the result via a callback.
When the API returns a structured error (e.g., an existing intent conflict), the second parameter of completionHandler is populated with a ThreeDSecureVerificationError. A transport-level failure populates the third parameter with a NetworkingError.
Parameters
The request payload containing the payment method to verify.
Callback invoked with (ThreeDSecureVerification?, ThreeDSecureVerificationError?, NetworkingError?).
