Support for library components in content and authoring templates | HCL Digital Experience

DX supports an image or file element in a content or authoring template to point to an existing library component. The API is added to retrieve the references to library components from content and authoring templates and to update/add these references.

GET - Retrieve data on references

When placing a GET request for content or for an authoring template, the reference is returned in the resourceUri element in the. libraryComponentReferenceURI field. Sample:
<resourceUri libraryComponentReferenceURI="/wps/mycontenthandler/!ut/p/digest!bwnkIBCsjNHRQuZQ53TKzg/wcmrest/LibraryFileComponent/a3bb731e-7029-4c81-a012-8c6530e10abc"></resourceUri>

PUT - Update library components

Similar to the GET, the PUT sets/adds library component references for file or image components. Note that a file element can only point to a file library component and an image element can only point to an image library component.

POST - create content with image library components or file library component references

For the creation scenario, the same pattern can be used to supply library component references.
