# Payto Payment Target Type for Wallee Transactions

## Target Type "wallee-transaction"

Name: wallee-transaction

Description:  Wallee Transaction

   A Wallee transaction is targeted by this payto target-type.
   It aims to allow refunding a transaction which was initiated
   by Wallee.

   For refunding a transaction using Wallee, this payto specification
   shall be used. To trigger a refund operation in Wallee, the merchant-reference
   of the transaction must be given as path parameter. The merchant reference is 
   specified by the merchant and is represented as string.

Syntax:

   payto-wallee-transaction-URI = "payto://wallee-transaction/" [ merchant-reference ]

   'merchant-reference' is a string which is given to the transaction by the merchant.
   
   The merchant-reference can be used at Wallee's transaction service to find the transaction.
