Changes to the record and updates from the users are displayed in the Chatter feed on the user's home page, which is a useful way to stay up-to-date with other users and with changes made to records in Salesforce. Feeds are available in API version 18.0 and later. If you move a custom field to the Recycle Bin, all FeedTrackedChange records that track historical changes to the custom field are automatically deleted and are not restored if the custom-field is undeleted. The following sections outline the difference between standard feeds and custom feeds. ## Standard Feeds A standard feed is a record feed, such as AccountFeed. FeedTrackedChange records for standard feeds can only be queried via the parent feed object. Note the following when working with standard feed items: - Feed items for standard feeds are read only in the API. - A FeedTrackedChange record is visible when you have read access on the record feed, and when the field is visible in the field-level security settings. ## Custom Feeds If you want more control over the information provided in a record feed, such as AccountFeed, you can create a custom feed. A custom feed can replace or augment an existing record feed. For example, you might want to: - Disable the standard account record feed and use an Apex trigger to generate FeedTrackedChange records for the events that you want to track in the feed instead. - Augment the standard contact record feed by writing an API client that inserts feed items for events that are not tracked in the standard feed. ## Tracking of Special Events The FieldName field also tracks other events that are not related to an individual field for a parent feed. These events occur as the parent record advances through its pipeline. For example, a value of leadConverted indicates that a lead has been converted to an opportunity. Valid values for the FieldName field for multiple objects: - created - ownerAccepted - ownerAssignment Additional valid values for the FieldName field for individual objects: Account - accountCreatedFromLead - accountMerged - accountUpdatedByLead - personAccountUpdatedByLead Case - closed - ownerEscalated Contact - contactCreatedFromLead - contactMerged - contactUpdatedByLead Contract - contractActivation - contractApproval - contractConversion - contractExpiration - contractTermination Lead - leadConverted - leadMerged Opportunity - opportunityCreatedFromLead #### See Also - [Custom Object\_\_Feed](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_objects_customobject__feed.htm "Represents the feed, specifically posts and feed-tracked changes, on a custom object.")
