TransactionId Property

Contains a unique transaction identifier.


char* GetTransactionId();
int SetTransactionId(const char* lpszTransactionId);
LPWSTR GetTransactionId();
INT SetTransactionId(LPCWSTR lpszTransactionId);
@property (nonatomic,readwrite,assign,getter=transactionId,setter=setTransactionId:) NSString* transactionId;
- (NSString*)transactionId;
- (void)setTransactionId:(NSString*)newTransactionId;
public var transactionId: String {
  get {...}
set {...} }

Default Value



This field contains a unique merchant-generated transaction identifier. This identifier must be 20 bytes in length and statistically unique. The class will then Base-64 encode the value for you prior to sending the value in the request.

Note: When submitting the TransactionId (XID) to your payment processor after ThreeDSecure authentication is completed, you may be required to submit the value in the 28-byte Base-64 encoded format. In such a case you can use the value contained within AuthenticationXID.
