Authorize.net XML Error E00002 - XML type not supported

Situation: I have a FileMaker solution that currently uses a payment gateway to handle credit card transactions. The transactions are submitted using XML and a URL Post. I use the Troi URL plugin to do the POST because FileMaker does not have this capability built in. There is no issue with this gateway, it's worked fine for years.

I am now trying to do the same thing with Authorize.net. Using their AIM XML guide, I have setup an XML "payload" to submit to the test URL. When I submit it I'm getting back the following Error message including the garbage characters at the beginning:

Ôªø<?xml version="1.0" encoding="utf-8"?><ErrorResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="AnetApi/xml/v1/schema/AnetApiSchema.xsd"><messages><resultCode>Error</resultCode><message><code>E00002</code><text>The content-type specified is not supported.</text></message></messages></ErrorResponse>
The Authorize.net description of this error is:

API Error Code: E00002
Error Code Text: The content-type specified is not supported.
Description: The only supported content-types are text/xml and application/xml.

My Troi URL plugin submission in FileMaker looks like this:

TURL_Post( ""; "https://apitest.authorize.net/xml/v1/request.api"; "xml=" & $XML_Payload )

The $XML_Payload is a script variable contains the sample XML code below. What I'm wondering is if Authorize.net expects some special string or code to say that this is "text/xml" coming in...

<?xml version="1.0" encoding="utf-8"?>

For anyone else who might be doing this, the answer was simply that I needed to include a "Custom Header" with my URL Post specifying the Content type as XML:

"Content-Type:text/xml"
