Why Choose Cleveroad’s API Development Services
Industry-specific integration experience
We’ve delivered 50+ API-driven projects across Healthcare, FinTech, Logistics, eCommerce, and Media. Our team knows how to meet HIPAA, PCI DSS, and GDPR requirements, integrate with EHRs, payment gateways, CRMs, and shipping APIs — all while minimizing third-party risks.
Secure and maintainable codebase
We apply secure coding practices from the start, with OAuth 2.0, JWT, and token-based access flows built in. Combined with modular architecture and strong access control practices, your APIs will be secure, easy to maintain, and ready to scale without regressions.
Rapid third-party API integration
We integrate 100+ third-party APIs for various purposes, from Stripe, PayPal, and Salesforce to Twilio, Google Maps, etc. Thanks to reusable patterns and prebuilt connectors, we reduce integration time and avoid disruptions caused by undocumented or unstable third-party changes.
Architecture-first approach
Before coding, we design your API architecture to match business workflows and future scale. This includes selecting the right protocol (REST, gRPC, GraphQL), defining endpoint logic, and planning for caching, rate limiting, and version control, resulting in a clean integration.
