I am having trouble sending URL encoded payload to eFax in FormData. Does anyone have experience working with the eFax? Their support is not the greatest. This is what I am trying to send

s rObj.ContentType="application/x-www-form-urlencoded"

d rObj.InsertFormData("id", "123456789")

d rObj.InsertFormData("xml", $zcvt(filestring,"O","URL"))

Any suggestion would be greatly appreciated.
