SOAP Service Deprecation Risk
With NetSuite SOAP nearing end-of-life, continued reliance on SOAP APIs posed significant business continuity and compliance risks.
NetSuite SOAP to REST Migration
Transformed Integration Agility for a Retail Furniture Business
Client Overview
A leading retail furniture company with a strong presence across both brick-and-mortar stores and e-commerce platforms relied heavily on Oracle NetSuite as its ERP backbone. The company managed everything, from product catalogs and inventory tracking to order processing and financial reporting within NetSuite. Over the years, multiple third-party integrations (e-commerce, logistics, and CRM) had been built using NetSuite SOAP Web Services, forming the core of its data exchange and automation.Business Objective
The client wanted to future-proof its integration ecosystem and modernize its existing NetSuite integrations to align with Oracle NetSuite’s latest roadmap, which is phasing out SOAP-based web services in favor of the more efficient SuiteTalk REST Web Services. Their primary aim was NetSuite SOAP to REST migration without any disruption and improve integration performance across systems.Industry

Read More Challenges
Rigid Integration Structure
SOAP-based integrations required extensive XML configurations and manual schema handling, making it difficult to onboard new systems or modify data flows quickly.
Slow Data Exchange
Order and inventory updates were delayed due to heavier payloads and sequential request handling in the SOAP framework.
Limited Support
The legacy SOAP endpoints used token-based authentication, which lacked the flexibility of OAuth 2.0 supported by REST.
High Maintenance
Each integration point had a separate WSDL and custom logic, making it hard to troubleshoot or enhance APIs as the business scaled.
See how we modernize NetSuite integrations for speed, scalability, and long-term resilience.

Assessment & Planning
We began the migration by conducting a comprehensive audit of all existing SOAP-based integrations, including those supporting product synchronization, inventory management, order processing, and customer data exchange. The team mapped each SOAP operation to its equivalent REST endpoint, using Oracle NetSuite’s SuiteTalk REST Web Services documentation as the foundation.
API Redevelopment & Data Model Alignment
Once the mapping was complete, our team rebuilt the existing SOAP integrations using Boomi and HTTP Client connectors. The team redesigned data payloads from XML to JSON to reduce latency and improve performance. To strengthen data accessibility, SuiteQL queries were implemented for efficient record retrieval, and OAuth 2.0 authentication was introduced to enhance security. The entire data flow was standardized under a canonical model to maintain consistency across all interconnected systems.
Incremental Migration & Testing
To avoid any business disruption, we adopted an incremental migration approach, transitioning modules in stages beginning with inventory, then orders, customers, and financial data. Each phase underwent parallel testing between SOAP and REST environments to validate functionality, data accuracy, and performance. Robust logging and monitoring were configured within Boomi to capture any discrepancies and ensure error-free execution.
Integration Optimization
Post-migration, we optimized data flows using an event-driven architecture with Boomi Event Stream and Solace. This shift from scheduled batch updates to real-time events ensured instant synchronization of inventory, pricing, and order statuses across e-commerce, CRM, and logistics systems. The optimization phase also included eliminating redundant API calls and streamlining data exchange, resulting in API response times that improved by more than 40%.
Post-Migration Enablement
Following deployment, we provided comprehensive documentation, performance reports, and technical training to our client’s internal IT and support teams. A structured API governance framework was established to streamline version control, change management, and future REST API upgrades. This empowered the client’s technology team to independently manage new integrations and maintain the REST-based ecosystem with confidence.
