Parsing data from HTTP Request in Handlebars

I have built (my programmer has) a Node API that communicates with a few other proprietary APIs for signing up to a service. Where we are stuck is at the payment page. To be compliant with our Credit Card provider we cannot have credit card data on our server so we send the client to an HPP (Hosted Pay Page) using a good old fashioned HTML form with some hidden fields. The HPP page takes the customer’s money and sends a response also using a HTTP POST form data. Is there a way to parse HTTP Form Post data in a handlebars theme?

No, handlebars can only generate html. Is there a reason the post request can’t be sent to the Node API?

Thanks for the response. I don’t see any reason the response cannot go back to our NODE API. My programmer is doing this now.
