Parameters
----------
to_import : array of dicts, csv/xml string, ``pandas.DataFrame``

If you pass a csv or xml string, you should use the
``format`` parameter appropriately.
:note:
Keys of the dictionaries should be subset of project's,
fields, but this isn't a requirement. If you provide keys
that aren't defined fields, the returned response will
contain an ``'error'`` key.
overwrite : ('normal'), 'overwrite'
``'overwrite'`` will erase values previously stored in the
database if not specified in the to_import dictionaries.
format : ('json'), 'xml', 'csv'
Format of incoming data. By default, to_import will be json-encoded
return_format : ('json'), 'csv', 'xml'
Response format. By default, response will be json-decoded.
return_content : ('count'), 'ids', 'nothing'
By default, the response contains a 'count' key with the number of
records just imported. By specifying 'ids', a list of ids
imported will be returned. 'nothing' will only return
the HTTP status code and no message.
date_format : ('YMD'), 'DMY', 'MDY'
Describes the formatting of dates. By default, date strings
are formatted as 'YYYY-MM-DD' corresponding to 'YMD'. If date
strings are formatted as 'MM/DD/YYYY' set this parameter as
'MDY' and if formatted as 'DD/MM/YYYY' set as 'DMY'. No
other formattings are allowed.
force_auto_number : ('False') Enables automatic assignment of record IDs
of imported records by REDCap. If this is set to true, and auto-numbering
for records is enabled for the project, auto-numbering of imported records
will be enabled.
