ContentDistribution

Represents information about sharing a document externally. This object is available in API version 32.0 and later.

Supported Calls

create(), delete(), describeSObjects(), query(), retrieve(), undelete(), update(), upsert()

Special Access Rules

Content deliveries must be enabled to query content deliveries.
Users (including users with the “View All Data” permission) can query only the files that they have access to. If the file is managed by a Content Library, the user must have “Deliver Content” enabled in the library permission definition and be a member of the library. If the file isn’t managed by a Content Library, the user must have the “Enable Creation of Content Deliveries for Salesforce Files” permission.
Users can query the DistributionPublicUrl and Password fields only if they are the file owner, if the file is shared with them, or if the RelatedRecordId specifies a record that the users can access.
If the shared document is deleted, the delete cascades to any associated ContentDistribution. The ContentDistribution is still queryable by using the QueryAll verb.
If the shared document is archived, the only fields that users can edit are ExpiryDate and PreferencesExpires.
Customer Portal users can’t access this object.
Guest users of Experience Cloud sites can't access or create this object.
Chatter Free users can’t access this object.

Usage

Use this object to create, update, delete, or query information about a document shared externally via a link or via Salesforce CRM Content delivery.

The ContentDistribution object supports triggers before and after these operations: insert, update, delete. It supports triggers after undelete.

Example

The VP of Marketing wants file authors to specify whether their files can be shared with external people using content delivery. He also wants some files to have a password. You can add a custom field DeliveryPolicy on the ContentVersion object. Make the custom field a picklist with the values, Allowed, Blocked, and Password required. Add the field to the ContentVersion layout so that the user can set the delivery policy per file. Then, add an insert trigger for the ContentDistribution object to enforce the rules based on the delivery policy set in the file.

The ContentVersionId for ContentDistribution must be unique.

Note

This trigger for the ContentDistribution object enforces the delivery policy rules for each file:

1trigger deliveryPolicy on ContentDistribution (before insert) {
2    for (ContentDistribution cd : trigger.new) {
3        String versionId = DeliveryPolicyHelper.getContentVersionId(cd);
4        ContentVersion version = [select DeliveryPolicy__c from ContentVersion where Id = :versionId];
5        String policy = version.DeliveryPolicy__c;
6        if (policy.equals('Blocked')) {
7            cd.addError('This file is not allowed to be delivered.');
8        } else if (policy.equals('Password required')){
9            if (!DeliveryPolicyHelper.requirePassword(cd)) {
10                cd.addError('To deliver this file, set a password.');
11            }
12        } 
13    }
14}

The trigger calls this helper class:

1public class DeliveryPolicyHelper {
2    public static String getContentVersionId(ContentDistribution cd) {
3        if (cd.ContentVersionId != null) {
4            return cd.ContentVersionId;
5        } else {
6            String versionId = [select LatestPublishedVersionId from ContentDocument where Id = :cd.ContentDocumentId].get(0).LatestPublishedVersionId;
7            return versionId;
8        }
9    }
10    
11    public static boolean requirePassword(ContentDistribution cd) {
12        return cd.PreferencesPasswordRequired;
13    }
14}

Apex has a per organization limit of 10 concurrent requests that last longer than 5 seconds. A trigger that uploads files can easily hit this limit.
