# Order Initialization for Payment Processing

> Learn how to initialize an order with the EnKash Payment Gateway. Generate a unique OrderID to streamline and manage your payment transaction lifecycle efficiently.

Creating an order is the first and critical step in processing a payment through the EnKash Payment Gateway. The Order API generates a unique `OrderID`, which acts as the core reference throughout the transaction lifecycle.
