What We OFFER
Our API Development and Integration Services
We offer a wide range of API development and integration services to help businesses enhance connectivity and improve functionality. Explore our key offerings:
01
Custom API Development
We build backend APIs with strict JSON schemas, typed data contracts, and interactive OpenAPI (Swagger) documentation. Every endpoint includes role-based access control and input validation to support web, mobile, and internal tool ecosystems.
02
API Integration and Middleware Architecture
Our team builds integration middleware and event-driven message brokers that sync data across CRMs, ERPs, and cloud databases. We implement automated payload transformation, schema mapping, and retry queues to prevent dropped transactions during service outages.
03
RESTful and GraphQL API Engineering
We implement RESTful architectures for standardized resource CRUD operations and GraphQL schemas for client-driven nested queries. Our implementations minimize network round-trips and optimize payload sizes for data-heavy platforms.
04
Legacy System and ERP Modernization
We wrap on-premise SQL databases, AS400 mainframes, and proprietary legacy software in secure RESTful API layers. This enables modern cloud applications to read and write core enterprise data without modifying the underlying legacy codebase.
05
Cloud-Native Microservices Architecture
We decouple monolithic backends into containerized microservices deployed on AWS (ECS/EKS), Azure, or GCP. Each service scales independently via container orchestration to eliminate single points of failure under peak traffic.
06
API Security, Gateway Management, and QA
We configure enterprise gateways (Apigee, Kong, AWS API Gateway) with OAuth 2.0, JWT validation, rate limiting, and WAF rules. Every endpoint undergoes automated regression testing, concurrency stress testing, and OWASP API security scans before release.
Our Process
Imaginovation follows a structured, six-stage Agile process designed to eliminate technical debt, prevent integration bottlenecks, and ensure predictable sprint deliveries:
OUR PROCESS - STEP 1
Discovery and Architecture Planning
Our technical architects analyze your data models, existing backend infrastructure, authentication protocols, and third-party dependencies. We establish integration boundaries and design the data flow to eliminate architectural bottlenecks before any code is written.
OUR PROCESS - STEP 1
Discovery and Architecture Planning
Our technical architects analyze your data models, existing backend infrastructure, authentication protocols, and third-party dependencies. We establish integration boundaries and design the data flow to eliminate architectural bottlenecks before any code is written.
OUR PROCESS - STEP 2
API Design and Specification
We practice contract-first design using OpenAPI (Swagger) standards. Our team defines data models, request/response structures, error handling protocols, and mock servers so frontend and external teams can begin building in parallel.
OUR PROCESS - STEP 3
Agile Development and Integration
We build in two-week Agile sprints, writing modular, type-safe code for business logic, database connectors, and third-party webhooks. Imaginovation deploys bi-weekly builds to secure staging environments so your team can test live endpoints against real payloads.
OUR PROCESS - STEP 4
Quality Assurance and Security Audits
Our QA engineers conduct automated integration tests, load tests (using Postman and k6), and OWASP API Security Top 10 vulnerability scans. We stress-test endpoints under high concurrency to verify sub-second response times and strict authentication barriers.
OUR PROCESS - STEP 5
Deployment and Gateway Configuration
We manage production deployment across your cloud infrastructure with automated CI/CD pipelines. Our team configures API gateways, SSL/TLS certificates, rate limiting, and web application firewalls (WAF) to guarantee secure, zero-downtime releases.
OUR PROCESS - STEP 6
Post-Launch Monitoring and Maintenance
Imaginovation provides SLA-backed monitoring covering uptime, latency spikes, error rate tracking (via Sentry and Datadog), and security patch management. We manage API versioning, deprecation roadmaps, and ongoing feature updates on a retainer or per-sprint basis.

Frequently Asked Questions
How much does custom API development and integration cost?
Custom API development at Imaginovation typically ranges from $15,000 to $35,000 for standard RESTful endpoints and third-party integrations, and $50,000 to $100,000+ for complex enterprise middleware and microservices architectures. We scope every project to your specific data models, security standards, and integration touchpoints following an initial technical discovery session. Contact our team to receive an itemized proposal with clear milestone pricing.
How long does it take to develop and integrate an API?
A focused custom API typically launches within 4 to 8 weeks, while complex enterprise integration projects involving legacy modernization or multi-system synchronization take 3 to 6 months. Imaginovation works in two-week Agile sprints, delivering working endpoints to staging environments after each cycle so you can test integrations continuously. We map out realistic milestone schedules during discovery before any code is written.
What types of APIs can you develop and integrate?
Imaginovation develops RESTful, GraphQL, gRPC, SOAP, and WebSocket APIs tailored to your application's architecture and performance needs. Whether you need public developer APIs, internal microservices communication, or asynchronous webhook processors, we select the protocol that optimizes bandwidth and execution speed. Our technical leads evaluate your workload to recommend the right architectural pattern.
How do you ensure API security and data compliance?
Imaginovation implements OAuth 2.0, JSON Web Tokens (JWT), role-based access control (RBAC), and TLS 1.3 encryption for all data in transit. We architect APIs in full compliance with HIPAA, PCI-DSS, SOC 2, and GDPR standards, conducting automated OWASP API Top 10 vulnerability assessments before deployment. Regular penetration testing and token rotation policies ensure your endpoints remain protected against unauthorized access.
Can you integrate modern apps with legacy or proprietary systems?
Yes, integrating modern platforms with legacy enterprise systems is a core specialty at Imaginovation. We build secure middleware wrappers, database bridges, and custom connectors that allow cloud applications to communicate with on-premise ERPs, mainframes, and proprietary SQL databases. This approach unlocks your core enterprise data without requiring a costly or disruptive system rebuild.
How do you handle API versioning and backward compatibility?
Imaginovation uses semantic versioning alongside URI path and header versioning strategies to ensure updates never disrupt existing client applications. When deploying new features or breaking changes, we maintain backward-compatible endpoints alongside detailed deprecation roadmaps. This structured lifecycle management gives partner developers and internal teams ample time to adopt new versions safely.
