If you use third-party tools to assist with NetSuite API Integration, there’s going to be a pretty big change coming. Oracle NetSuite has announced the end of using SOAP web services endpoints. Starting with the NetSuite 2026.1 release, beginning mid-February 2026 and continuing through the end of April 2026, Oracle NetSuite will no longer provide a SOAP web services endpoint with each release.

So, what does this mean for you and your API integrations?

NetSuite API Switch Announcement

If you are using Oracle NetSuite solutions that are developed, owned, and maintained by Oracle NetSuite (like NetSuite Connector, NSPOS, or SuiteProjects Pro), you don’t have to worry. Those solutions will not be affected under the updated policy.

However, if you are using custom or third-party SOAP integrations with external API integration platforms, like the One iPaaS, you’ll want to make sure you’re prepared for how those integrations will be affected.

What You Need to Know

In this policy change, new SOAP endpoints will only be released when necessary for business, technical, or other important reasons. This means you may have to make some changes to your current integrations to keep everything running smoothly.

What is Changing?

The 2025.2 SOAP web services endpoint will be the last regularly scheduled and released SOAP endpoint. After that, it is recommended to transition to REST integrations.

Policy Timeline

This policy change takes effect with the NetSuite 2026.1 release. An important timeline to keep in mind is:

  • 2026.1: No new SOAP endpoints released
  • 2027.1: All new integrations must use REST
  • 2028.2: SOAP integrations no longer function

All SOAP web services endpoints are supported for three years after their release date, and with each new NetSuite release, the oldest SOAP web services endpoint is switched off automatically.

Recommended Actions

When it is made available, NetSuite recommends upgrading your client applications to use the 2025.2 SOAP web services endpoint to ensure the longest possible support period (3 years). After that, you need to migrate to REST integrations to ensure your processes are prepared for the future.

NetSuite API Integration

When you build new integrations, use the REST web services and the OAuth 2.0 authentication method. Also, consider migrating your existing integrations to REST web services and the OAuth 2.0 authentication method. REST web services are the recommended integration channel and meet the latest industry requirements.

SOAP API vs REST API

NetSuite is transitioning to using REST APIs because they allow for more scalability, flexibility, and are easier to maintain. Doing this ensures they keep up with business best practices. SOAP API’s have more structure and are less flexible for more modern integration needs.

Whether you’re building new API integrations or simply transferring your current integrations, switching to NetSuite’s REST API allows your workflows to grow with you.

SmartConnect API Integration Capabilities

eOne’s SmartConnect allows you to take control of every part of your integration through a consistent and user-friendly interface that doesn’t require developers or coding knowledge to use.

  • Integrate as a source or destination with all your data in Oracle NetSuite via the SuiteTalk API.
  • Trigger your integration when you want—manually, scheduled, or based on a webhook.
  • Utilize Saved Searches and SuiteQL queries to extract data from NetSuite.
  • Enjoy a simple point-click and flexible mapping experience.
  • Link together steps and tasks to complete your business process automation.

Popdock API Integration Capabilities

With Popdock’s virtual integration, you can embed and display data from anywhere in your other apps using Popdock widgets. With the use of a Popdock widget, you can embed a Popdock list or multiple lists directly into your NetSuite user interface, either as a tab at the top menu or as custom content on your dashboard or page. Provide a real-time look into your REST API data to other team members who need to be able to view and report on the data conveniently in their app.

Closing Thoughts

If you still utilize SOAP endpoints, it’s time to transition. Don’t delay the switch and risk integration failures. Completing this upgrade with eOne Solutions will ensure your integration processes remain functional and future-proof.
