# Trigger Exchange payment

When the shopper makes the exchange payment, this API creates a transaction record in the RKFL system. 

A crypto transaction may take 2 min to 2 hours to complete the transaction. When a crypto transaction is initiated successfully, this API returns the immediate status of the transaction, which can be pending/processing/canceled/completed. 

The RKFL wallet receives all crypto transactions and settles with the merchant daily. 

The merchant can set up a webhook through the merchant portal to receive updates on every status change in the RKFL system. The merchant must set up only one webhook for crypto and bank transfer. 

This API receives the request payload in an encrypted format, where the encryption algorithm is RSA, and the encryption key is the merchant's public key.
