End of Support for Vertex Cloud REST APIs v1

As part of Vertex’s commitment to providing the best possible service and support, our team will be ending support of REST v1 endpoints as of December 31, 2025.

We encourage you to transition to the latest version of our API to continue receiving the best possible support and to take advantage of new features and improvements. Please note, after December 31, 2025, Vertex will no longer provide support, updates, or bug fixes for REST v1.

To assist with this transition to REST v2, we have prepared the RESTful API v1 to v2 Code Changes Guide to lead you through the process.

There are field changes between REST v1 and REST v2 that must be made to ensure continuity in the flow of your integration. The guide highlights the before and after values of fields that have changed. You can use the guide to find and replace the values you are using in your integration.

The Vertex Developer Network has documentation of the REST v1 APIs and the REST v2 APIs for further information.

If you have questions about this change, please contact Vertex Customer Support via Vertex Community.
