Published content vs. preview

You can use Delivery REST API either to retrieve published content or to preview content.

Preview content – Get the latest versions of content items. The latest version can come from both published and unpublished content items.
Published content – Get the published versions of content items.

In both cases, you use the same endpoints to request data but with a different base URL.

To preview content from your project's environment, use:
https://preview-deliver.kontent.ai/<YOUR_ENVIRONMENT_ID>/
To retrieve published content from your project's environment, use:
https://deliver.kontent.ai/<YOUR_ENVIRONMENT_ID>/
