Response

The response from this method is always data in CSV format, rather than XML, because the amount of data returned can be substantial. CSV response minimizes overheads and allows for seamless integration with third party code/systems. Response content type is „text/csv”.

Returned data contains a header with column names in the first row only when Columns element have been specified in the request. If the Columns element have not been specified the CSV file will include data from all the columns in a data table without the header.

SV output is formatted using following settings:

Field separator: comma (,)
Quoting character: („)
Escape character: („)
Encoding: UTF-8
