send XML data for credit card processing

I’m trying to implement submission of an XML document from my website for credit card processing using my merchant’s API.

Here’s the format I’m using for my request. For some reason I keep getting an error message telling me “Invalid Request Format. XML request is not well-formed or request is incomplete.”

I know the XML itself is correct, as I can submit it directly through the URL string in the browser and it works OK.

Here’s what I’m doing:

<cfsavecontent variable="strXML">

<!--- NOTE: test data below -- not my real data --->
<txn>
<ssl_merchant_ID>123456</ssl_merchant_ID>
<ssl_user_id>123456</ssl_user_id>
<ssl_pin>V6NJ3A</ssl_pin>
<ssl_transaction_type>ccsale</ssl_transaction_type>
<ssl_card_number>1111111111111111</ssl_card_number>
<ssl_exp_date>1210</ssl_exp_date>
<ssl_amount>2.34</ssl_amount>
<ssl_salestax>0.00</ssl_salestax>
<ssl_cvv2cvc2_indicator>1</ssl_cvv2cvc2_indicator>
<ssl_cvv2cvc2>321</ssl_cvv2cvc2>
<ssl_invoice_number>1234</ssl_invoice_number>
<ssl_customer_code>1111</ssl_customer_code>
<ssl_first_name>customer</ssl_first_name>

<ssl_avs_zip>55555</ssl_avs_zip>
<ssl_phone>555-555-5555</ssl_phone>
<ssl_email>customer@email.com</ssl_email>
</txn>

</cfsavecontent>

<cfhttp url="https://www.myvirtualmerchant.com/VirtualMerchant/processxml.do?xmldata=" method="post">
<cfhttpparam type="XML" value="trim(strXML)">
</cfhttp>

<cfoutput>#cfhttp.FileContent#</cfoutput>



Can someone tell me what I’m doing wrong?
