Pre-authorization API

📄️Pre-authorization

By calling this interface, the merchant generates a 'Pre-authorization' transaction order in the PayCloud backend. The system returns the payment checkout URL or payment parameters, which the merchant can use to invoke the payment page and guide the user to complete the credit card pre-authorization.

📄️Pre-authorization Capture

This interface initiates the final settlement (capture) after a successful pre-authorization. It is used in scenarios like hotels, rentals, or e-commerce where funds are frozen first and then captured. Only one capture request is allowed for each pre-authorization transaction.

📄️Pre-authorization Void

Used to cancel a successful pre-authorization. Upon success, the system immediately unfreezes the user's funds and restores their credit limit. Only one void operation is allowed per pre-authorization.
