Hi @SRINI_VASU, when using the XML-RPC API you will need to reference custom fields via their “Database name”. This can be found under Admin \> Settings \> General \> Set up custom fields for: Contact \> View the field database names (for the API). You also need to prepend the database name with an underscore which indicates that it is a custom field like this: `_CustomFieldName`.
