get_custom_field Method
Gets a custom field value from QuickBooks.
Syntax
def get_custom_field(field_name: str) -> str: ...
Remarks
This method will get the value of a custom field, which has been defined by the user from within the QuickBooks UI.
To read the values of custom fields, be sure to set qbxml_version to at least "2.0" when retrieving data from QuickBooks. Then, QuickBooks will return custom field information, and it will be accessible through this method.
You may also invoke config to read the value of custom fields. However, to set the value of custom fields you must set qbxml_version to at least "3.0" and invoke set_custom_field.
