I've you've searched other posts, they've not doubt recommended that you URL Encode your parameters, put the access token in a <cfhttpparam><\/a>, specify a content type, etc.<\/p>\n

But, there's one ColdFusion specific "issue" that many posts neglect.<\/p>\n

That "issue" is the way ColdFusion stores structure keys – all uppercase.<\/p>\n

If you've Serialized a Structure to a JSON object, the keys will be all uppercase. Furthermore, if you are sending parameters that come from a structure, they need to be properly "cased".<\/p>\n

See the example below:<\/p>\n

<cfset oRequest[1] = {method = "GET", relative_url = "me"}>
\n\t<cfset oRequest[2] = {method = "GET", relative_url = "me\/friends?limit=50"}><\/code><\/p>\n

\t<cfset oRequest = SerializeJSON(oRequest)>
\n\t<cfset oRequest = Replace(oRequest, "METHOD", "method", "ALL")>
\n\t<cfset oRequest = Replace(oRequest, "RELATIVE_URL", "relative_url", "ALL")><\/code><\/p>\n

<cfhttp url="https:\/\/graph.facebook.com" method="POST">
\n\t    <cfhttpparam type="url" name="access_token" value="#arguments.access_token#">
\n\t    <cfloop collection="#postParams#" item="param">
\n\t        <cfhttpparam type="url" name="#lcase<\/strong>(param)#" value="#postParams[param]#">
\n\t    <\/cfloop>
\n\t<\/cfhttp>   
\n\t<\/code><\/p>\n

Note the lcase wrapping the parameter. This may not apply to all parameters, but it's important to note that the parameter is case-sensitive.<\/p>\n","protected":false},"excerpt":{"rendered":"
