Custom API Development and Integration Services
Ready to boost your business in weeks, not months
What is 3rd party API integration?
Third-party APIs are provided by external parties — such as Twilio, Twitter, or Google — to allow developers to access their functionality. API (Application Programming Interface) gives programmers the ability to connect their custom applications with external systems either in the network or cloud. This helps speed up development time and cut costs.

API Security

At Xenneo Tech, we understand that APIs can introduce additional security risks by expanding the potential entry points for malicious actors. Therefore, we prioritize careful design and robust security controls when developing APIs. Our comprehensive approach to API security includes implementing advanced measures for authentication, authorization, privacy, non-repudiation, and attack prevention. Our engineers ensure that APIs are developed with full support for the latest security and regulatory standards, including JOSE (JWK, JWS, JWE), PCI-DSS, and GDPR. By adhering to these standards, we provide end-to-end protection to safeguard your applications and data from potential threats.

API Testing Automation

At Xenneo Tech, we offer comprehensive end-to-end testing solutions for both REST and SOAP APIs. Our approach includes unit testing, functional testing, and load testing to evaluate the performance of individual APIs, their overall functionality, and the efficiency of API layers. Our QA team meticulously logs and monitors calls for frequently used API functions to ensure thorough coverage and reliability. By leveraging these testing methods, we ensure that your APIs meet the highest standards of performance and functionality, providing a seamless experience for your users.

API Adoption

At Xenneo Tech, we facilitate the swift onboarding of your developers by providing comprehensive materials that showcase the features of your solution. Our team creates user-friendly API documentation and developer portals, complete with code samples for every API endpoint across multiple programming languages. We also offer auto-populated sandbox API keys and other essential resources to streamline the adoption process. By delivering these well-designed elements, we ensure that developers can easily understand, integrate, and utilize your API, accelerating their productivity and enhancing their overall experience.
