Activemerchant Barclays EPDQ

Hi Guys,

I was just wondering if anyone has got activemerchant to work with
epdq payment gateway. There is a billing gateway for it
but there are no examples or topics of people using it(probably because
one of the more expensive options). Ive successfully used other
payment gateways fine but this is proving quite troublesome.

It seems im connected ok but im getting back an unhelpful response

“action”=>“purchase”, “amount”=>100, “success”=>false,
“authorization”=>nil, “message”=>“The HTTP content is not valid.”,

Im going through the barclays documentation and think i have everything
setup correctly but cant seem to get past this no matter what i try.

Any help would be appreciated,
