A server-to-server Full-Code API integration allows merchants to process payments directly from their website or application, with full control over the checkout experience and payment orchestration.
This integration model is designed for merchants that want to own the entire payment flow, from order creation to payment status handling, while relying on the SIBS Gateway for secure payment processing.
As this model involves direct interaction with payment data, merchants choosing the Full-Code API are responsible for assessing and ensuring compliance with applicable security and PCI DSS requirements.
By avoiding hosted payment pages, merchants can deliver a seamless and fully branded checkout experience, optimized for performance and conversion.
Note: If your business model does not require direct handling of card data, or if you want to simplify PCI DSS compliance, you may opt for the SIBS Payment Form integration instead.
This approach reduces PCI scope by ensuring that sensitive card data is not processed within your systems.
Full details are available on the dedicated Payment Form integration page.
Who should use this integration
This integration model is intended for:
- Merchants with technical teams and API expertise
- Merchants requiring customized checkout and payment logic
- Merchants integrating payments into complex backend environments

How it works

How to do it
A Full API (server-to-server) integration allows your systems to connect directly to the SIBS Gateway, giving you full control over how payments are created, processed and managed within your own environment.
With this model, your team owns the entire payment lifecycle, from order creation to final status handling, while leveraging the SIBS Gateway for secure transaction processing.
To get started:
- Create an order: From your server, call the appropriate API endpoint to create a new order.
- Receive the order response: The gateway returns the order details required to proceed with the payment flow.
- Submit the payment request: Using the data collected from the shopper, send the payment request securely from your backend.
- Handle the payment status: Analyze the payment response and define how your website or application should react about success, failure, retry, or alternative flow.
Additionally, on the order creation , you may include enriched payment parameters that enhance transaction security, optimize authorization rates, and enable additional types of transactions when required
Before you start
Getting started with SIBS Gateway is straightforward. Before beginning your Full API integration, please ensure the following steps are completed:
