@Vinod_Rath I would recommend using the REST API to work with custom fields for Contacts.

Use [GET /contactCustomFields](https://developer.infusionsoft.com/docs/rest/#!/Contact/listCustomFieldsUsingGET) to view the custom fields that you have configured.  
Use [PATCH /contacts/{contactId}](https://developer.infusionsoft.com/docs/rest/#!/Contact/updateContactUsingPATCH) to update a Contact with values for the custom fields you want.

The body of the PATCH /contacts/{contactId} request might be something like:

```
"custom_fields": [
 {
  "id": 2,
  "content": "B0018ZW7CA"
 },
 {
  "id": 0,
  "content": "2017-04-28T14:33:00-0700"
 }
]

```
