The http module doesn't seem to properly send the headers so all attempts at authentication for both an OAUTH2 and Basic Auth APIs failed. I verified all functionality with Postman and also my own PHP scripts. First email to support received a reply, "Just checking if you solved this issue" but they did say they are investigating on their end. After 8 days and 3 (4 counting the last message when I told them I refunded the product) emails, still no response. This product had so much potential but the support just wasn't there. I'm editing here as there is no way for me to respond to your reply. You replied and said problem resolved internally and you would help with a solution yet you've still done nothing. No responses any emails or help requests and haven't reached out as stated. The problem of the http request node remains. So the original review stands.
