When working with Salesforce CMS Content (Managed Content Object) and attempting to retrieve content using Apex, you may encounter the following error when utilizing methods from the ManagedContent Class methods such as getManagedContentByContentKeys or getManagedContentByIds.
ConnectApi.ConnectApiException:[errorCode=INSUFFICIENT_ACCESS]: "You don't have access to this channel."
This error occurs because of ConnectAPI.ManagedContent is designed for regular workspace APIs. For enhanced workspaces (and channels), you should use the ConnectAPI.ManagedContentDelivery class instead.
Here’s an example of how to use Lightning Web Components (LWC) to display CMS Content (Collection) as an accordion on a public Lightning Web Runtime (LWR) site, leveraging the ConnectAPI.ManagedContentDelivery class. In this example, I use the getCollectionItemsForChannel method from the ConnectAPI.ManagedContentDelivery class to retrieve CMS Collection items and display them as an accordion. Additionally, you might come across an error when parsing and passing data from Apex to LWC, as described in this known issue. The article also provides a workaround for this problem:
public without sharing class CmsCollectionAccordionLWC {
@AuraEnabled(cacheable=false)
public static List<CMSContent> getCMSContentByContentKey(String ContentKey){
try{
system.debug('ContentKey: '+ContentKey);
String channelId = ConnectApi.ManagedContent.getAllDeliveryChannels(0, 1).channels[0].channelId;
system.debug('channelId: '+channelId);
ConnectApi.ManagedContentCollectionItems data = ConnectApi.ManagedContentDelivery.getCollectionItemsForChannel(channelId, contentKey, NULL);
List<CMSContent> CMSContents = getCollectionCMSContent(data, channelId);
system.debug('return data: '+CMSContents);
return CMSContents;
}catch(Exception e) {
throw new AuraHandledException(e.getMessage());
}
}
public static List<CMSContent> getCollectionCMSContent(ConnectApi.ManagedContentCollectionItems data, String channelId) {
try {
List<CMSContent> CMSContents = new List<CMSContent>();
CMSContent CMSContentObj = new CMSContent();
CMSContentObj.contentKey = data.collectionKey;
CMSContentObj.contentType = data.collectionType.fullyQualifiedName;
CMSContentObj.mainTitle = data.title;
//CMSContentObj.unauthenticatedUrl = data.urlName;
list<ContentItem> ContentItemsObjList = new list<ContentItem> ();
for(ConnectApi.ManagedContentCollectionItem item: data.items){
ContentItem ContentItemObj = new ContentItem();
ContentItemObj.key = item.id;
ContentItemObj.title = item.name;
ConnectApi.ManagedContentDeliveryDocument newsData = ConnectApi.ManagedContentDelivery.getManagedContentForChannel(channelId, item.id, true);
String.ValueOf(newsData?.contentBody?.get('body'));
ContentItemObj.body = String.ValueOf(newsData?.contentBody?.get('body'));
ContentItemsObjList.add(ContentItemObj);
}
CMSContentObj.ContentItems = ContentItemsObjList;
CMSContents.add(CMSContentObj);
return CMSContents;
}catch(Exception e) {
throw new AuraHandledException(e.getMessage());
}
}
public class CMSContent {
@AuraEnabled public string contentKey {get; set;}
@AuraEnabled public string contentType {get; set;}
@AuraEnabled public String mainTitle {get; set;}
@AuraEnabled public list<ContentItem> ContentItems {get; set;}
}
public class ContentItem {
