What must be included in the request to edit an existing object record in Salesforce?

To edit an existing object record in Salesforce, including the Internal ID field is essential because it uniquely identifies the specific record that you want to modify. Salesforce uses this ID to locate the existing record within its database. When you send a request to change any information about a record, the system needs this identifier to ensure that it updates the correct entry.

If the Internal ID is omitted, Salesforce would not know which record you are referring to, leading to errors or the inability to execute the request. This enables precise and accurate editing of records and ensures data integrity within the platform.

The other potential choices are not necessary to perform an edit operation. New field data, while it is often included in a request to specify what changes are being made, is not mandatory for the request itself. Document IDs and deletion codes are not relevant for the context of editing a record, as they typically pertain to other functionalities in Salesforce, such as file management or deleting records.
