Authorize.net integration problem

[Lakshman]

I am trying to integrate Authorize.net SIM API into django views.

I am facing a problem in the fingerprint generation. I am repeatedly
getting that the fingerprint generated doesn't match the one the
server generates.

I have generated the md5 hash with the key provided as specified in
the SIM documentation.

Here is the code:

params = {
'x_login' : '4ffrBT36La',
'x_amount' : '100.00',
'x_show_form' : 'PAYMENT_FORM',
'x_type' : 'AUTH_CAPTURE',
'x_method' : 'CC',
'x_fp_sequence' : '123',
'x_version' : '3.1',
'x_relay_response' : 'FALSE',
}
params['x_fp_timestamp'] = int(time.time())

msg = '^'.join([params['x_login'],
str(params['x_fp_sequence']),
str(params['x_fp_timestamp']),
str(params['x_amount'])
])+'^'

fingerprint = hmac.new('9LyEU8t87h9Hj49Y',msg).hexdigest()


I would be glad if some one that has dealt with this earlier, points
out what the glitch is. Thanks in advance.

How are you getting this? Server error? You're not giving us enough
information.

Are they expecting the results in a specific order... because as you
probably know a dictionary is never in the order that you add the items.

Yup. Unusual, it is.

But thats how their string specification syntax is. It includes a ^ at
the end.

have you printed msg and checked it is formatted correctly? i
have node
idea what the protocol is, but your use of join and string
concatenation
in the generation of msg looks unusual to me.
