Q: Woocommerce Custom Payment Gateway We are planning to use a payment gateway that does not have a standard woocommerce plugin. Before we did that, I wanted to know is it even possible to do this? 
Basically we will have the API from the Payment gateway (in PHP) and will need to make calls to get a payment processed and send a success / failure response to Woocommerce - 
Is this even possible? If so, any leads / documentation on how to do this would be highly appreciated.
