Custom Interface Development & API Services

Enterprise custom interface development delivering robust, scalable, and secure integration solutions. Expert API development encompassing RESTful services, SOAP web services, GraphQL, data transformation, error handling, comprehensive testing, and professional API documentation.

RESTful API Development

Design and implementation of RESTful APIs following industry best practices and HTTP standards. Resource-oriented design, proper HTTP methods (GET, POST, PUT, DELETE, PATCH), status codes, JSON/XML response formats, pagination, filtering, sorting, and HATEOAS principles ensuring intuitive and scalable API interfaces.

  • REST API Design & Architecture
  • Resource Modeling & URI Design
  • HTTP Methods & Status Codes
  • JSON & XML Response Formats
  • Pagination, Filtering & Sorting
  • HATEOAS Implementation
  • RESTful Best Practices
  • API Versioning Strategies

SOAP Web Services

Enterprise SOAP web service development providing strongly-typed, contract-first integration solutions. WSDL (Web Services Description Language) design, XML schema definition, SOAP message handling, WS-Security implementation, SOAP fault handling, and enterprise service bus (ESB) integration.

  • SOAP Web Service Design
  • WSDL Contract Development
  • XML Schema Definition (XSD)
  • SOAP Message Handling
  • WS-Security Implementation
  • SOAP Fault Handling
  • MTOM (Message Transmission Optimization)
  • ESB Integration

GraphQL API Development

Modern GraphQL API development enabling clients to request exactly the data they need. Schema design, query and mutation development, resolver implementation, subscriptions for real-time data, DataLoader for N+1 optimization, and GraphQL security best practices including query complexity analysis and rate limiting.

  • GraphQL Schema Design
  • Query & Mutation Development
  • Resolver Implementation
  • Subscriptions for Real-Time Data
  • DataLoader & N+1 Optimization
  • GraphQL Security (Query Complexity, Rate Limiting)
  • Federation & Schema Stitching
  • Apollo Server & GraphQL Tools

Data Transformation & Mapping

Complex data transformation and mapping logic enabling seamless data exchange between heterogeneous systems. JSON to XML transformation, XSLT processing, JSONata expressions, field mapping, data enrichment, format conversion, and transformation testing ensuring accurate and reliable data integration.

  • JSON to XML Transformation
  • XSLT Processing
  • JSONata Expressions
  • Field Mapping & Data Enrichment
  • Format Conversion (CSV, JSON, XML, EDI)
  • Data Validation & Cleansing
  • Transformation Logic Testing
  • Mapping Documentation

Error Handling & Resilience

Robust error handling patterns and resilience strategies ensuring reliable interface operations. Retry logic, exponential backoff, circuit breaker patterns, fallback mechanisms, dead letter queues, error logging and monitoring, graceful degradation, and comprehensive error response design.

  • Retry Logic & Exponential Backoff
  • Circuit Breaker Patterns
  • Fallback Mechanisms
  • Dead Letter Queues
  • Error Logging & Monitoring
  • Graceful Degradation
  • Timeout Management
  • Error Response Design

API Documentation & Developer Portal
