The Preview tier is now deprecated following our new versioning policy. You have until the end of 2026 to migrate to either the current stable 2026.07 version or the upcoming release candidate 2027.01, which will be available soon.
The preview version lets you see what changes are likely to be released in the next stable version so that you plan accordingly.The preview version is based on the latest stable version. Generally, new changes will be in the preview version for at least a month before going to a quarterly stable version.This version can be called using “preview” as the version number:

While the changes will likely be released in the stable version, there is always a chance that they might not be released. A feature might be added and removed later before making it to the stable version. Because of this, it’s recommended that you do not use the preview version in your production environment.If you’re interested in testing the preview version, you can check out its documentation in this section.
For the stable endpoints and other detailed documentation, you can check the current Criteo API version.
