Transaction Response Fields in the Payment Gateway Response

[authorizeK]

Hello I'm new with authorize.net and i'm trying to get familiar with it i have been seen some examples to understand better how it works,  But I do have a question for the Transaction Response Fields in the Payment Gateway  Response.

I want to get the las 4 digits of the credit card number and I read that order 51(account number) gives that, but I don't know how to get it i tried just to read it in that position but it seems like nothing is in it

thanks in advance

What about the other 50+ fields? are they all blank?

I ran an example a simple payment with the following fields

            post_values.Add("x_login", "XXXX")
            post_values.Add("x_tran_key", "XXXXXX")
            post_values.Add("x_test_request", "TRUE")
            post_values.Add("x_version", "3.0")
            post_values.Add("x_currency_code", "USD")

            post_values.Add("x_type", "AUTH_CAPTURE")
            post_values.Add("x_delim_data", "TRUE")
            post_values.Add("x_delim_char", "|")
            post_values.Add("x_relay_response", "FALSE")
            post_values.Add("x_method", "CC")

            post_values.Add("x_card_num", textbox_creditcardnumber.Text.Trim)
            post_values.Add("x_exp_date", textbox_expdate.Text.Trim)

            post_values.Add("x_amount", textbox_paymentauth.Text.Trim)
            post_values.Add("x_description", "description")

            post_values.Add("x_first_name", textbox_creditcardholder.Text.Trim)
            post_values.Add("x_last_name", textbox_creditcardholderlname.Text.Trim)

And when I read the values it gives me 1-38 some of the fields are blank but still reads the position, then I just tried to read

array(50) to see if anyway it had the account number but no there is no blank value there it seems like if that position didn't exist.

Thanks again for your help!

Version 3.0

The version 3.0 response contains system

fields from position 1 to 38 and echoes

merchant-defined fields from 39 on,

in the order received by the system.

The version 3.1 response string contains

68 system fields with field number 39

representing the Card Code (CVV2/CVC2/CID)

response code. Merchant-defined fields

are echoed from field 69 onward. Merchants wishing to use the Card Code feature and

merchants who accept partial authorization tran

sactions must use transaction version 3.1.
