Which Salesforce object is crucial for tracking approval history?

The Approval History object is essential for tracking approval history within Salesforce because it specifically stores all records related to the approval process of a particular record. This object captures data about each approval step, including who approved or rejected the record, the timestamps for these actions, and any comments made during the approval process. By leveraging the Approval History, users can easily audit and review the approval workflow, helping them understand the decision-making journey and maintain transparency in the process.

The other options refer to different aspects of the approval workflow but do not function as direct record keepers of the approval history. The Approval Request typically pertains to the initial submission of a record for approval, while Approval Status indicates the current state of an approval process, such as pending or approved. The Approval Queue deals with managing pending approvals but does not capture the historical data like Approval History. Thus, the Approval History object is the most accurate choice for tracking all aspects of the approval history in Salesforce.
