Data API v2

Updated Endpoints

Improvements to Bulk CMS Authoring via Create Collection Item(s)
You can now create multiple CMS items using the original POST endpoint for creating collection items. By including the items property in your request, you can pass either a single item object or an array of objects. This functionality complements the bulk Create Items endpoint, offering more flexibility for CMS authoring.

Introducing the localeId Parameter
To align with our updated query parameter naming conventions, we’re introducing the localeId parameter as a replacement for locale. While locale is still supported for compatibility, localeId is now the preferred parameter. The following endpoints are affected:


Data API BETA

New Endpoints

List Form Submissions by Site
This endpoint differs from the existing List Form Submissions endpoint by accepting siteId as a path parameter and elementId as a query parameter. Use this parameter to filter submissions on a site by the formElementId. This is particularly helpful for forms included in components, which are given a different formId for each component instance, while still keeping the same formElementId across instances. The formElementId is an attribute from each form object in the List Forms API. Using this endpoint, you can pass the siteId and the formElementId to get all form submissions for a single form that appears in multiple component instances.
