We need help working with Popshops Datafeed API calls. We have the template built on our end and making API calls based on a Popshops sample script. We need to make this script more robust. We need you to take the existing template and add more functionality such as a call for product comparisons and coupons. We have attached a MS Doc file explaining everything that we need.
