PayU Standing Instructions Parameters

Step 1: Create a SI parameters object

Create a class PayUSIParams object using the code similar to the following:

//Swift
let siParam = PayUSIParams(billingAmount: <String>,
paymentStartDate: <Date>,
paymentEndDate: <Date>,
billingCycle: <PayUBillingCycle>,
billingInterval: <NSNumber>,
billingLimit: <PayuBillingLimit>,
billingRule: <PayuBillingRule>)

/* Objective C */
PayUSIParams *siParam = [[PayUSIParams alloc] initWithBillingAmount:<#(NSString * _Nonnull)#>                                                   paymentStartDate:<#(NSDate * _Nonnull)#>                                                     
paymentEndDate:<#(NSDate * _Nonnull)#>                                                       billingCycle:<#(enum PayUBillingCycle)#>                                                    billingInterval:<#(NSNumber * _Nonnull)#>];
