What Happened - The Official Policy Shift
NetSuite (Oracle) is phasing out its legacy SuiteTalk SOAP Web Services in favor of the modern SuiteTalk REST Web Services.The 2025.2 release will be the last planned NetSuite SOAP endpoint, and no new SOAP web services will be introduced after that point. NetSuite REST Web Services are the recommended modern alternative for integration.
NetSuite recommends building all newly built integrations with REST using OAuth 2.0. Existing SOAP-based integrations will continue to function during the transition period but should be migrated to REST before SOAP is retired. Organizations should plan to replace SOAP with REST to ensure continued support and security.
KingswaySoft's Advantage: We offer a custom-built, sophisticated solution to simplify this migration, ensuring a smooth,
low-risk, and easy-to-implement transition to SuiteTalk REST.
Key Timeline: The Countdown to 2028.2
Oracle’s official documentation outlines a strict phased removal:
- 2025.2: Las Planned SOAP Endpoint
The 2025.2 SuiteTalk SOAP web services endpoint is the last scheduled SOAP release.
After this, new SOAP endpoints will only be created if there is a clear technical business need. - 2026.1: New SOAP Endpoints No Longer Included By Default
Beginning with the 2026.1 release, Oracle NetSuite will no longer include a new SOAP endpoint with every release. Later SOAP endpoints will only be introduced if necessary for specific business or technical requirements. - 2027.1: New SOAP Integrations Disallowed
According to the Removal Plans FAQ, with the 2027.1 release,
you will not be able to build new integrations using SOAP web services; REST is the recommended default. - 2027.2: Minimum Support Threshold
Only the 2025.2 SOAP endpoint will be supported. Older SOAP WSDL versions will still be accessible but will be considered unsupported endpoints and will not receive bug fixes or security enhancements. Integrations will need to be re-architected to REST, as SOAP WSDL support ends. - 2028.2: SOAP Web Services Removed (EOL)
With the 2028.2 release, SOAP web services will no longer be available in NetSuite, and any existing
SOAP integrations will stop working if they are not migrated to REST or RESTlets.
Why the Deprecation Timeline is Critical
Relying on legacy SOAP beyond these dates exposes your business to immediate service disruption. SOAP is being deprecated due to its outdated technology stack, which limits support for modern architecture standards, new features, and security protocols. When connections cease to function, you risk:
- Data synchronization failures.
- Security vulnerabilities (SOAP relies on token based authentication, which is less secure than REST's OAuth 2.0).
- Compliance issues and incompatibility with modern record types (SOAP's exposed objects do not support the latest business features).
Why Migrate Early?
NetSuite’s official SOAP Web Services deprecation reflects
a platform-wide shift toward modern, REST-based integration standards.
Modernizing your existing NetSuite integration is crucial to ensure compatibility with future updates and to avoid disruptions as NetSuite phases out SOAP support.
REST Web Services are the
Strategic Direction
REST is the long-term standard. SOAP no longer receives functional investment, while REST provides modern API patterns, improved performance, OAuth 2.0 authentication, and access to new NetSuite features / record types.
SOAP Web Services are
Functionally Limited
Many newer NetSuite capabilities are made for the REST API. SOAP Web Services are in maintenance mode, so organizations that delay migration may lose access to new features or face rushed integration redesigns.
Clear Deadline,
Real Risk
SOAP Web Services will be removed, with 2025.2 as the final planned SOAP version. After this, all SOAP-based integrations will stop working, making proactive migration essential to avoid business disruption.

Technical Details: What’s Changing Under the Hood
The retirement of SOAP web services in Oracle NetSuite signals a major evolution in how businesses connect, automate, and scale their integration workflows. At the heart of this change is the transition from the long-standing SOAP API to a modern REST architecture, designed to deliver enhanced performance, security, and flexibility for all NetSuite integrations.
With the 2025.2 release currently planned as the final SOAP endpoint, Oracle NetSuite is shifting its investment toward REST web services. This means that existing SOAP integrations will need to be reimagined using REST API endpoints to ensure ongoing compatibility and support. The REST API migration is not just a technical upgrade, it is a move toward a more robust integration channel that leverages modern security standards, including OAuth 2.0 for managing access tokens and securing data exchanges.
REST web services in NetSuite now support a wide range of operations, including create, read, update, and delete (CRUD) actions on core record types. This allows organizations to replace most existing SOAP solutions with REST equivalents, streamlining integration workflows and enabling easier navigation between related records. The REST API also exposes record metadata and supports advanced features for custom integrations, making it possible to combine multiple operations and support bulk-style integrations through REST endpoints and RESTlets for greater efficiency.
For businesses with custom or complex integration needs, the transition from SOAP to REST may require some adaptation, especially if certain SOAP operations or record types are not yet available in REST. However, NetSuite is actively working toward full REST parity, and SuiteScript RESTlets offer a flexible alternative for bridging any remaining gaps. This ensures that even the most specialized business processes can be supported as you move away from outdated technology stacks.
To prepare for the end of SOAP support, it is essential to audit your current NetSuite environment, identify all existing SOAP integrations, and map out a REST migration plan. Start by reviewing which business processes rely on SOAP endpoints, assess the availability of REST web services for those needs, and determine where custom RESTlets may be required. Taking these steps now will help you avoid last-minute disruptions and ensure your integration channel remains secure and future-proof.
NetSuite provides resources such as the SOAP Web Services to REST Web Services Upgrade Guide to help you navigate the migration process. Additionally, you can schedule a free discovery call with NetSuite experts to get personalized advice on replacing SOAP web services and optimizing your integration strategy.

Do not wait for the final planned endpoint, start planning your migration today to keep your NetSuite account running smoothly and securely in the new era of web services.
Action Plan for Businesses and Developers
The gradual sunset of SOAP places a critical mandate on IT departments and developers:
- Audit Existing Connections: Review all integration platforms (iPaaS, custom apps, automation frameworks) connecting to NetSuite to determine their current reliance on SOAP endpoints or WSDL versions. During migration, some organizations may need to support both SOAP and REST to ensure a smooth transition and allow for dual-operation testing and validation.
- Prioritize Migration: Move critical business flows to SuiteTalk REST well before the final 2028.2 removal to avoid service disruptions. Understanding the differences between SOAP and REST is critical for planning a successful migration and ensuring compatibility between integration processes.
- Address Functionality Gaps: For specific record types or operations not yet exposed by SuiteTalk REST, NetSuite suggests using custom RESTlets (custom endpoints via scripting) as a necessary transition bridge.
- Validate Vendors: Contact all third-party integration vendors to confirm their roadmap for delivering REST-based connectors ahead of the 2028.2 deadline.

FAQ
Yes. Oracle NetSuite has officially announced the phased deprecation of SuiteTalk SOAP Web Services. NetSuite documentation confirms that SOAP is being retired in favor of SuiteTalk REST Web Services, which is positioned as the long-term, strategic integration platform.
According to official NetSuite documentation, the 2025.2 release is the final planned SOAP endpoint. In later releases, SOAP support becomes increasingly limited, and SOAP Web Services are scheduled to be fully removed from the NetSuite platform starting with the 2028.2 release.
NetSuite’s officially recommended replacement for SOAP Web Services is NetSuite REST Web Services. REST provides modern API architecture, improved performance, broader feature coverage for newer record types, and supports OAuth 2.0 authentication, which is now the preferred security standard.
Existing SOAP integrations will continue to function only during the supported transition window. NetSuite has confirmed that once SOAP Web Services are removed in the 2028.2 release, all SOAP-based integrations will permanently stop working and must be replaced with REST-based solutions.
For scenarios where SuiteTalk REST does not yet expose a required record or operation, NetSuite documentation recommends using SuiteScript RESTlets to create custom REST endpoints. This approach allows organizations to remain REST-compliant while addressing temporary feature gaps. NetSuite is actively working toward functional parity and feature parity between SOAP and REST web services, with ongoing investment to close any remaining gaps.
NetSuite REST Web Services are being developed to achieve both functional parity and feature parity with SOAP Web Services. REST supports CRUD operations, bulk data imports, and easier access to NetSuite records, with ongoing enhancements to match SOAP's capabilities and record types.
The phased nature of the SOAP retirement means organizations must inventory existing integrations, validate vendor readiness, and transition to REST well ahead of the final removal. Early planning reduces business risk, avoids rushed rewrites, and ensures uninterrupted data integration as NetSuite enforces its modern API standards. Additionally, web services with OAuth are now the standard for secure integrations, making it essential to update authentication methods during migration.
