Single API for multiple payment systemsSuperface.ai is a language and protocol for abstracting integrations to application use cases. This approach gives you a framework to decouple your application’s lifecycle and the integrations it uses. Superface.ai is the successor to the API protocol that enables companies to communicate directly, efficiently, and quickly with each other.
Their open-source SDK can manage fast-growing organizations, complex architectures, and maintenance without hiring highly skilled engineers. The company believes that autonomous APIs, decoupled components, and self-managed clients are the basis for future interfaces and AI.
Radek NovotnýCo-founder and CEO at Superface.aiWe are impressed with how Relevant handled the entire process. The way the company communicates and its pragmatic approach to problem-solving are remarkable. Their extensive experience, professionalism, and impeccable communication have become the key to our fruitful cooperation.
Superface.ai surveyed its customers and discovered that the most popular request was the integration of its product with the most common payment processing systems. The payment gateway plays a vital role in the customer’s shopping process as it ensures the security and confidentiality of the customer’s sensitive information.
Therefore, they decided to hire a reliable IT consulting company to help them test the possibility of writing one API for several payment platforms. We had extensive hands-on experience in third-party integrations, so Superface.ai decided to cooperate with our company.

PayPal’s payment processing system offers a convenient, fast, user-friendly, and secure solution to online payment both for the product owners and end customers.

Stripe supports secure and smooth payments for online stores and retailers, subscription companies, software platforms and marketplaces, and more.
Our team of dedicated experts ran the discovery phase to get answers to essential questions and clarify the vision of product usage. We validated the Superface concept of writing one API for several payment systems by creating a demo and testing its market viability. Our team wrote several use cases for payment systems (Stripe, Paypal). Moreover, we implemented use cases for determining the location using the IP address.
