    Key Results

    65%

    Reduction in Manual Processes

    Custom API development automated order syncing, billing, and reporting workflows. For SaaS and logistics clients, this eliminated 65% of repetitive data entry, freeing teams to focus on customer engagement and growth.

    50%

    Faster Feature Deployment

    API integration services reduced rollout times by 50%. FinTech and HealthTech platforms launched payment modules, compliance reporting, and patient data features weeks earlier, accelerating time-to-market and revenue capture.

    Our API Development & Integration Process

    A proven framework to design, build, and optimize secure, scalable, and business-ready APIs.

    Discovery & Requirement Analysis

    We begin by understanding your business workflows, data flows, and integration needs. This stage defines which systems require APIs, what endpoints are necessary, and how APIs will improve efficiency or unlock new features.

    API Architecture & Planning

    We design the required architecture: REST or GraphQL APIs for communication, PostgreSQL for structured data, and cloud strategies on AWS, Azure, or Google Cloud for reliability and scale. Planning includes authentication methods, data governance, and compliance requirements.

    Design & Development

    Our team builds clean, modular APIs tailored to your operations. Integrations can include Stripe for payments, Plaid or Yodlee for financial data, Twilio for communication, or Google Maps for location services. We ensure APIs are well-documented and optimized for long-term performance.

    Third-Party API Integration

    We connect your product with external services, such as QuickBooks API for accounting, Firebase for authentication, or UPS/FedEx APIs for logistics.

    Quality Assurance & Testing

    Every API undergoes functional, load, and security testing. Automated tests validate endpoints, while stress testing ensures APIs perform reliably under high user activity. This minimizes downtime and guarantees stable operations across environments.

    Deployment & Scaling

    Using DevOps and CI/CD pipelines, we release APIs quickly and consistently. Docker supports efficient deployments, while cloud platforms like AWS and Azure ensure effortless scaling as demand increases.

    Ongoing Support & Optimization

    We monitor APIs post-launch, provide troubleshooting, and roll out version updates as platforms evolve. Through automation with Zapier or Make.com, we simplify workflows and keep integrations efficient as your business grows.

    Case Studies

    Transforming workflows through applied AI

    DEVtrust built a multilingual e-learning platform that unifies animated storybooks, vocabulary tools, audio narration, and interactive globe features. By using text-to-speech (TTS) APIs and pre-recorded audio, we ensured learners gained an immersive language experience. Multiple narrators and languages were enabled through the Web Audio API, ensuring high-quality playback and control. The platform delivered measurable impact with a 40% increase in engagement, a 35% improvement in vocabulary acquisition, and a 30% rise in positive feedback, reflecting stronger interactivity and accessibility.

    Precina needed a secure solution to improve medication management, patient engagement, and data handling. DEVtrust delivered custom API development and integration, using Clinical API to enable real-time synchronization between web and mobile applications. We added reminder notifications, pop-up alerts tied to health readings, and OTP-based authentication to protect sensitive data. These solutions achieved a 98% reduction in manual efforts, a 95% increase in user trust, a 97% improvement in document handling, and a 92% boost in agent productivity. This resulted in cleaner workflows, stronger compliance, and better patient care.
