API Development: REST, SOAP, and gRPC

Scalable REST APIs – Lightweight and widely adopted
Secure SOAP APIs – Ideal for enterprise & regulated industries
High-Performance gRPC – Optimized for microservices & streaming
Multi-Protocol Support – Tailored to project-specific needs
Robust Security Standards – OAuth, JWT, and encryption mechanisms

In application development today, APIs underpin the bulk of the communications occurring internally between several products/services/systems/devices. With expertise in REST, SOAP, and gRPC methodologies, we are able to develop robust, scalable APIs for high performance and meeting different business needs.

RESTful APIs: We develop REST APIs that are lightweight, stateless, and scalable using Spring Boot, Express.js, and Flask for JSON Data Exchange. OAuth2, JWT Authentication, and role-based access controls (RBAC) ensure secure interactions.

SOAP Web Services: SOAP APIs are implemented in WCF and JAX-WS for companies needing highly (>structured messaging), delivering WS-Security, XML Encryption, and schema validation for regulated industries like finance and healthcare.

gRPC for High-Performance Microservices: Low latency, high-speed APIs for real-time applications, IoT, and inter-microservice communication are built with gRPC and Protobuf, while multiplexed and bidirectional streaming is enabled on HTTP/2.

API Gateways & Management: AWS API Gateway, Kong, or Apigee are integrated for throttling, caching, monitoring, and analytics to ensure top performance with secure delivery.

Versioning & Backward Compatibility: The versioning strategy-preserving URI, header-based, and/or content negotiation-ensures maintainability and backward compatibility of APIs for a long time to come.

Testing & Monitoring: Automated testing using Postman, SoapUI, and JMeter is performed for functional correctness, security, and load handling before any deployment.

Integration & Compliance: APIs support third-party integrations, fintech protocols (ACH, ISO 20022), and regulatory compliance (PCI DSS, HIPAA, Open Banking) for industry solutions.

Combining cutting-edge frameworks, best-in-class security, and cloud-native API management, we build endurable, efficient, and future-ready API solutions duly tailored according to business requirements.

FAQs

What are the key differences between REST, SOAP, and gRPC?
REST, SOAP and gRPC are very different from each other with respect to their underlying principles. REST is the lightweight mean of communication chiefly employed in web services. In contrary, SOAP is a protocol with strict standards in security. Last, but not least, gRPC has high-performance capabilities,
and streaming is one of the options listed under its features.
When should I use gRPC over REST or SOAP?
gRPC is intended to replace REST or SOAP used for internal communications between microservices at low latency for applications that are highly throughput-oriented.
Is SOAP still relevant for building APIs today?
Yes, because SOAP is an interface specification that everyone knows and understands where you may require high security and compliance to transactions-for example, finance or healthcare industries.
Which type of API is most suited for mobile applications?
Most likely REST API, as proved by its simplicity, lightness, JSON usage, and seamless operation with mobile and web apps.
What kind of security would that ensure on such protocols?
OAuth; API keys; JWT tokens; TLS encyption; and such methods such as WS-Security for SOAP.
