Enterprise Application Integration Services

Flexsin offers a full spectrum of enterprise integration services including integration strategy and architecture, API design and management, application integration, cloud and hybrid integration, data integration and ETL, B2B and EDI integration, IoT device integration, legacy system integration, and 24/7 managed integration operations with SLA-backed support.

We are certified on MuleSoft Anypoint Platform, Azure Integration Services (Logic Apps, Service Bus, API Management), WSO2 Enterprise Integrator, TIBCO BusinessWorks, Jitterbit Harmony, Software AG WebMethods, Dell Boomi, IBM App Connect, and Apache Camel. We recommend the right platform based on your existing technology landscape, team capabilities, and long-term integration strategy.

An ESB (Enterprise Service Bus) is an on-premises middleware layer - a central hub that routes, transforms, and mediates messages between enterprise applications. iPaaS (Integration Platform as a Service) is the cloud-hosted equivalent - providing the same integration capabilities as managed services with elastic scalability and lower infrastructure overhead. Many modern platforms like MuleSoft support both deployment models.

Integration security is built in from the architecture phase - not added afterwards. We implement OAuth 2.0 / OpenID Connect for API authentication, mutual TLS (mTLS) for transport security, data masking and field-level encryption for sensitive payloads, rate limiting and threat protection at the API gateway, and full audit logging. For regulated industries we apply GDPR, HIPAA, SOX, PCI-DSS, and sector-specific compliance frameworks as baseline requirements.

Yes. Legacy integration is one of our core specialisations. We use API wrapping (exposing COBOL programs as REST services), data extraction via JDBC/ODBC adaptors, message transformation from proprietary formats to modern schemas, and adapter-pattern bridges on MuleSoft or IBM ACE that allow mainframe and COBOL systems to participate as first-class integration participants without modifying legacy code.

B2B EDI integration connects your enterprise systems with trading partners, suppliers, and distributors through standardised document exchange protocols. We implement EDI X12 and EDIFACT transaction sets (850 Purchase Orders, 856 ASNs, 810 Invoices), AS2 or AS4 secure communication channels, trading partner onboarding, EDI-to-XML/JSON transformation, and automated routing of inbound EDI documents to ERP, WMS, or OMS systems.

We implement the full API lifecycle - starting with design-first OpenAPI 3 specification, followed by implementation, API gateway configuration (Kong, AWS, Azure APIM, or MuleSoft), security policy enforcement (OAuth, rate limiting, IP filtering), Swagger developer portal setup, versioning strategy, and real-time monitoring with alerting. We treat APIs as products - with governance, discoverability, and long-term maintainability as design goals.

A single point-to-point integration (e.g. Salesforce-SAP) takes 4-8 weeks. A medium-complexity programme connecting 3-5 systems takes 3-5 months. A full enterprise integration platform implementation with API governance and managed services takes 6-12 months. Timeline depends on the number of systems, data complexity, security requirements, and whether an integration platform is already in place. We provide a detailed estimate after an initial discovery session.

Our standard managed integration SLA offers 99.9% uptime for production integration flows, P1 incident response within 1 hour, P2 within 4 hours, and P3 within 1 business day. We provide monthly SLA reports, real-time monitoring dashboards, and dedicated integration operations engineers for enterprise retainer clients. Custom SLA tiers are available for mission-critical healthcare, financial, and government integration environments.

IoT integration connects edge devices, sensors, and industrial equipment to enterprise platforms - enabling real-time telemetry ingestion, device management, and event-driven business processes. We configure MQTT and AMQP brokers, implement AWS IoT Core, Azure IoT Hub, or GCP IoT Core, build data transformation pipelines from device payload formats to enterprise data models, and create event-driven triggers that update ERP, MES, or maintenance management systems based on device events.

Yes - this is one of the most common enterprise integration programmes we deliver. We build bidirectional flows between Salesforce CRM, SAP ERP (via SAP Integration Suite, BAPIs, or IDocs), and Microsoft systems (Dynamics 365, SharePoint, Teams, Power Platform) using MuleSoft or Azure Integration Services as the central hub - enabling real-time order, customer, inventory, and financial data synchronisation across the enterprise.

Data quality is enforced at the integration layer through schema validation (rejecting malformed payloads before they reach target systems), transformation and normalisation logic, deduplication rules, mandatory field enforcement, and error routing with DLQ (Dead Letter Queue) handling for failed records. For MDM scenarios, we implement master record matching and survivorship rules to ensure a single source of truth across connected systems.

Yes. We implement both cloud-native integrations (fully hosted on AWS, Azure, or GCP with managed services) and hybrid integrations (where on-premises systems connect to cloud platforms via secure VPN, PrivateLink, or on-premises integration agents). Most enterprise clients have a mix of cloud SaaS and on-premises legacy systems, and our architecture accommodates both in a unified, governed integration landscape.
