## API Version: default


# Txns API



This API supports both creation of order and transaction and authorizing the transaction. Pass the apple pay/Google pay token in transient_info to complete the transaction. 


#### **Processing Apple Pay Transactions** 



1. After the customer successfully authenticates the payment, the **Apple Pay SDK**  returns a **payment token** .
2. The merchant must forward this token to the **Txns API**  to complete the transaction.
