Add context records to an existing table using a CSV file. The CSV file must contain a header row with column names for the attributes you want to map.
File size can be a maximum of 300 MB or 500,000 records. If the CSV file exceeds these limits, compress it as a ZIP file. A compressed ZIP file must contain only one CSV file.
Use the value of the "operation" parameter to "append" the added data or "replace" the existing data.
