&udf_values=val
&access_token=token-value
To add more than one list value with a single API command, you need to have encoded the tab character separator in your API command.
This example adds xxx, yyy and zzz as values to a UDF named my_field.

The optional access_token parameter allows you to use a valid OAuth2 token obtained with the get_token command. If you provide the access_token parameter, then the user_id and password parameters should not be provided. This prevents the password being sent in clear text over your network connection.
