Public Oath API

[Palas]

When I try the below Adobe Coldfusion code found below, the respnose I get back is html code for an adobesign login page.What am I doing wrong?

The code below has placeholders obviously, but the live code has the real values.

<cfhttp url="https://secure.na2.echosign.com/public/oauth" method="get" result="httpResp0" timeout="60" >
<cfhttpparam type="FORMFIELD" name="username" value="email" />
<cfhttpparam type="FORMFIELD" name="password" value="password" />
<cfhttpparam type="FORMFIELD" name="scope" value="user_login:self+agreement_send:account" />
<cfhttpparam type="FORMFIELD" name="client_id" value="clientid" />
<cfhttpparam type="FORMFIELD" name="redirect_uri" value="www.anyurl.com" />
<cfhttpparam type="FORMFIELD" name="response_type" value="code" />
