Callback
Callback
Callback allows you to integrate your Nochex payments with your website's back-end operations, so you get immediate confirmation and authentication of the Nochex payments you receive. It's very similar to our Nochex APC system. It allows you to:
• Process your customers payments in real-time
• Give immediate feedback to your customer
• Store your Nochex payments in your own database
Callback can be integrated into the Nochex checkout system to allow you to create a payment system that alleviates the need for you to log into the Nochex system to confirm that payments have been made. The customer will also benefit from the Callback as they will receive an immediate response to the order they have placed, similar to that of making payments through a credit card system.
How does the Nochex Callback work?
The Nochex Callback system works by sending a confirmation POST to a page on your server. Once your server has received a response from our servers, you can process the information to allow you to construct an email or update an order on your website / shopping cart in relation to a payment that has been made, and whether it has been a AUTHORISED or DECLINED transaction.
How do I apply for Callback?
To use the Callback functionality - you will need to contact support who can enable this feature for you.
