Tip Adjust
Tip Adjust enables you to offer your US-based restaurants a traditional, receipt-based tipping workflow for both magstripe and EMV transactions. Contact your account manager to activate this feature.
Run Charge and Provide Printed Receipt
The waiter takes the payment card from the guest back to the POS System and runs a CHARGE transaction for the invoice amount (excluding any tips). Your POS System then prints merchant and shopper receipts that include lines for Tip and Total Amount.
The guest receives their payment card together with the printed receipts from the waiter and can fill in the desired Tip and/or Total Amounts on the merchant receipt at their discretion. If required, the customer also provides their signature. After the guest has left, the waiter collects the receipt and stores it for later Tip Adjust.
To perform a
CHARGE
 that can be Tip Adjusted later on, modify the MPTransactionParameters to include the
tipAdjustable = YES
 property for the initial transaction:
MPTransactionParameters *tp = [MPTransactionParameters chargeWithAmount:[NSDecimalNumber decimalNumberWithString:@"10.00"]
                                                                                                                           currency:MPCurrencyUSD
                                                                                                                          optionals:
                                                           ^(id<MPTransactionParametersOptionals>  _Nonnull optionals)
                                                           {
                                                                   optionals.subject = @"Bouquet of Flowers";
                                                                   optionals.customIdentifier = @"yourReferenceForTheTransaction";
                                                                   
optionals.tipAdjustable = YES;

                                                           }];
                                                           
// Start the transaction as usual via [MPTransactionProvider startTransactionWithParameters:]
Make sure to always provide printed merchant and shopper receipts and print the lines for Tip and Total Amount if
printTipLine
 equals
YES
.
Performing Tip Adjust
At the end of the shift or business day, the waiter can perform the Tip Adjust on the respective transactions. It is not required to perform a zero-amount adjust for transactions without tip.
To implement Tip Adjust, your POS System needs to allow the waiter to first relocate the transaction (e.g., by entering a POS-provided invoice number printed on the payment receipt), and then to specify the Tip Amount as written down by the guest.
To perform a Tip Adjust, you create
MPTransactionParameters
 that contain the
transactionIdentifier
 of the transaction that should be adjusted and the Tip Amount (not the Total Amount) that should be added:
MPTransactionParameters *tp =
   [MPTransactionParameters tipAdjustForTransactionIdentifier:transactionIdentifier
                                                                                                        optionals:
        ^(id<MPTransactionParametersTipAdjustOptionals>  _Nonnull optionals)
        {
                
[optionals setAmount:[NSDecimalNumber decimalNumberWithString:@"2.00"] currency:MPCurrencyUSD];

        }];

// Pass the parameters to [MPTransactionProvider amendTransactionWithParameters:]
To find out whether the Tip Adjust was successful, check for
MPTransactionProcessDetailsStateApproved
 in the
completed
 block.
Implementation Considerations
  • 20% Adjust Limit:
     As per card scheme rules you can perform a Tip Adjust for up to 20% of the original invoice amount. Higher amounts will be rejected.
  • Printed Receipts:
     The Tip Adjust workflow is based on printed merchant and shopper receipts, so make sure your POS System implements them.
  • Invoice Number:
     In order to make it easy for the waiter to retrieve transactions for Tip Adjust, we strongly recommend that you print a short, POS-provided invoice number on each receipt. Your POS System should then store the
    transactionIdentifier
     as part of your invoice data.
  • 24 Hour Time Limit:
     It is possible to run a Tip Adjust up to 24 hours after the initial
    CHARGE
    . You can determine this also programmatically via the
    MPTransaction
     object by checking for
    MPTransactionTipAdjustStatusAdjustable
     as the
    transaction.details.tipAdjustStatus
    .

 to include
tipAdjustable(true)
 for the initial transaction:

TransactionParameters transactionParameters = new TransactionParameters.Builder()
                .charge(new BigDecimal("10.00"), io.mpos.transactions.Currency.USD)
                .subject("Bouquet of Flowers")
                .customIdentifier("yourReferenceForTheTransaction")
                .tipAdjustable(true)
                .build();

// Start the transaction as usual via TransactionProvider.startTransaction()
Make sure to always provide printed merchant and shopper receipts and especially ensure to print the lines for Tip and Total Amount if
isTipLineRequired()
 equals
true
.
