In order to utilize the End Of Day tipping feature, it will first need to be enabled on TMS. This can be enabled via a TMS Request.

ChipDNA API Calls

Once you have successfully processed a sale transaction using ClientHelper.startTransaction( ), you will need to call ClientHelper.confirmTransaction( ) two separate times.

First Confirm

The first confirmTransaction( ) should be called with the following mandatory parameters:

ParameterSet.add(ParameterKeys.Reference, string userReference)
ParameterSet.add(ParameterKeys.CloseTransaction, "false")

This will partially commit the transaction and allow it to be refundable.

Second Confirm

The second confirmTransaction( ) should be called with the following mandatory parameters:

ParameterSet.add(ParameterKeys.Reference, string userReference)
ParameterSet.add(ParameterKeys.Gratuity, string gratuityAmount)
ParameterSet.add(ParameterKeys.CloseTransaction, "true")

This will add the gratuity and fully commit the transaction, qualifying it for settlement. 
*gratuityAmount value is in minor units e.g. “123” for $1.23
