Which method is used to retrieve details about updated records?

The method used to retrieve details about updated records is 'getUpdated()'. This method is specifically designed to return a list of records that have been modified during a specified time frame. By using this functionality, developers can effectively track changes and synchronize data between Salesforce and external systems.

The context for this method is particularly relevant in scenarios where maintaining up-to-date information across platforms is critical, such as in integration tasks. This allows for efficient data management as users can identify and handle only those records that require attention due to their recent updates.

The other options serve different purposes: 'getDeleted()' is intended for fetching records that have been deleted, while 'search()' is used for finding records based on specific search criteria. 'retrieve()' generally retrieves records based on specific identifiers or queries but does not focus specifically on updates. Therefore, 'getUpdated()' stands out as the correct method for accessing updated record details.
