Checkout.com Integration

6B are trusted engineering partners for organisations adopting Checkout.com’s modular payments infrastructure. We deliver reliable connectivity to Checkout.com’s Payment, Tokens, Customers, Payouts, Disputes, and Events APIs, ensuring smooth authorisation flows, reduced friction, and optimised acceptance rates. From discovery and compliance alignment to build, testing, deployment, and ongoing optimisation, we ensure your platform integrates seamlessly with Checkout.com’s global payments ecosystem.

Our mission is to help organisations accelerate their payment capabilities, expand internationally, and create frictionless, secure checkout experiences at scale.

Understanding Checkout.com Integration

Checkout.com is a modern, API-first global payments platform that supports card acquiring, digital wallets, alternative payment methods, payouts, and advanced fraud and risk tools. Its unified payments infrastructure enables merchants and financial platforms to process transactions seamlessly across multiple regions, currencies, and channels, making it ideal for high-growth fintechs and global ecommerce businesses.

Checkout.com’s integration model centres on REST APIs and webhook-driven event flows. Your system can initiate payments, authenticate customers via 3D Secure 2, manage stored payment methods using tokenisation, handle refunds and reversals, automate payouts, and respond to real-time events such as disputes and chargebacks. The platform also provides powerful fraud detection and risk scoring features through its Risk API, helping organisations reduce fraud while maximising authorisation success.

To comply with card network requirements and ensure secure payments, integrations must include strong authentication (SCA), secure card data handling, PCI DSS-aligned processes, encryption, and structured error handling. A well-designed Checkout.com integration supports high-volume, multi-market payments with strong reliability, transparency, and user experience.

Our Checkout.com Integration Process

Our Checkout.com integration process begins with a discovery phase where we work with your technical, operational, and compliance teams to define your payment flows, merchant requirements, risk controls, and customer experience goals. We identify which Checkout.com APIs you need — such as Payments, Tokens, Customers, Sources, or Payouts — and map them to the relevant checkout and back-office workflows.

Once requirements are clear, we design a secure and scalable integration architecture that incorporates tokenisation flows, 3D Secure authentication, webhook processing, chargeback handling, fraud rules, and payout orchestration. Our architects ensure the solution aligns with PCI DSS standards, SCA requirements, and Checkout.com’s technical specifications.

Using 6B’s reusable integration components — including tokenisation modules, webhook routers, secure API clients, and reconciliation utilities — we accelerate delivery while maintaining resilience and best-practice security. During development, we embed monitoring, error-handling, and retry logic to support high-volume transaction processing across multiple regions.

Testing includes simulating card payments, wallet transactions, failed authorisations, SCA flows, refunds, payouts, and dispute events. We work with Checkout.com to complete onboarding steps, compliance checks, and pre-production certification. After deployment, we implement real-time monitoring, reconciliation processes, dispute tracking, and performance optimisation.

We also provide long-term support to keep your integration aligned with Checkout.com’s API updates, new payment method releases, rule changes, and evolving regulatory requirements across global markets.
