When configuring the Write Records smart service to modify an existing author, what must the record ID contain?

• A. The author's email address
• B. The record ID must correspond to an existing author
• C. The record's creation timestamp
• D. A random internal key

Answer: (B)

When updating an existing author with the Write Records smart service, you must provide the unique identifier that points to the exact row in your data source. That identifier is the record ID, and it must correspond to an existing author. This ensures the service knows which row to update in the table. Using an email address isn’t reliable because it may not be unique and can change. A creation timestamp isn’t a stable key and isn’t guaranteed to identify a specific row. A random internal key isn’t meaningful or stable across runs. Only a value that exists in the data source as the author’s primary key (the record ID) will correctly locate the record to modify.
