Thanks Corey

Perhaps I am not explaining myself correctly about merchant accounts

for testing, the interaction I was using with authorize.net was the following

1) build an HTTP request object using

https://test.authorize.net/gateway/transact.dll

and

x_login=cnpdev9999&x_tran_key=Sjeb2h9Q9BfNEYKk&x_m ethod=CC&x_type=AUTH_CAPTURE&x_amount=1.00&x_delim _data=TRUE&x_delim_char=|&x_relay_response=FALSE&x _card_num=4111111111111111&x_exp_date=052009&x_tes t_request=TRUE&x_version=3.1

then return an HTTP Response using this request - for example it would return

"1"|"1"|"1"|"(TESTMODE) This transaction has been approved."|"000000"|"P"|"0"|""|""|"1.00"|"CC"|"aut h_capture"|""|""|""|""|""|""|""|""|""|""|""|""|""| ""|""|""|""|""|""|""|""|""|""|""|""|"

The assumption that I am making is somehow the x_login or x_trankey is somehow tied to the merchant account. Is this correct?

thanks
