signature in coldfusion

I'm trying to do a connectivity test to a third party company called Pacnet (payment processing company).  They're requiring I pass to them a signature.  I'm trying to do this in coldfusion using a test page..

however, I get:

authenticationFailed
This server could not process your request because: Authentication failed due to incorrect user name, password, or signature.

My question is does the hash of the string look correct as well as the utc time?

Seems like a convoluted method for the hash they require.  

You take a string "artis,#utctime#", then hash it.  
Then you take that hashed string, append ",baseball" to it and hash it again.  
Not sure the value of double-hashing something.  

You got a link to any Pacnet API documentation?

Anyway... another thing you can do is use <cfhttp> to post your form to their server, rather than create a normal form that you manually submit.  You probably know that, I guess you're just using a normal form to test what the values look like.

Ok, so I'm passing parameters to the server.  Now, how can I return the response?
<cfset curDate = Now()>
<cfset utcDate = DateConvert("local2utc", curDate)>
<cfoutput>
<cfset utctime="#DatePart('yyyy', utcDate)#-#DatePart('m', utcDate)#-#DatePart('d', utcDate)#T#DatePart('h', utcDate)#:#DatePart('n', utcDate)#:#DatePart('s', utcDate)#Z"><br />
current utc date/time: #utctime#<br /><br />
<cfset hash1 ="#Hash('artis,#utctime#', 'MD5')#">
<cfset hash2 ="#Hash('#hash1#,[hidden]', 'MD5')#">

well it seems to, but it depends what the pacnet page is expecting.  

try doing <cfdump var="#cfhttp#"> and see what the headers are.

lines like this:
<cfparam name="attributes.Timestamp" default="<cfoutput>#utctime#</cfoutput>">
you don't need the cfoutput, just do
<cfparam name="attributes.Timestamp" default="#utctime#">

I'm still confused about the requirement for double hashing.
