Renaissance,

Thanks.

I wonder why I keep getting 99 response code from authorize.net instead of payment page?

any ideas of things I could check

Maybe I have misunderstood the model here,

When I post a request to the SIM server with the SHA512 hash do I create the hash with

cc_authorize->CalculateFP(491)-INFO: loginid [5kBLZFWp34N8]

cc_authorize->CalculateFP(492)-INFO: sequence[39076]

cc_authorize->CalculateFP(493)-INFO: tstamp [1560427287]

cc_authorize->CalculateFP(494)-INFO: amount [122.50]

cc_authorize->CalculateFP(495)-INFO: currency[USD]

cc_authorize->CalculateFP(496)-INFO: data [5kBLZFWp34N8^39076^1560427287^122.50^USD]

Generating x_fp_hash[ 592f5f13f1af02431333d35d7a833a14d01a592b2c7194ab62c35114209de7d902

9EA621152718235C7FB060C4A44EE6F03F3C70A3107554CC332430 ]

Then in my x_relay_url I check with it with the decoding of the fields outlined on page 73 of the SIM manual?

When I do the above I get:

The following errors have occurred.
(99) This transaction cannot be accepted.

Solution Found:

The code in this post was correct. The issue was when we generate the Finger Print and then submit the form, the form was missing x_currency_cod='USD'.

This requirement was hidden really well in the docs
