Configure error message responses, and make sure that they dont show any sensative information to the user, but also explains what the issue was (e.g. "username is taken", "email already registered").
Create response classes to be able to configure what is being sent back as response in postman when a correct request is made:
gameAdsResponse - Show = full gameAd + only username of seller.
orderResponse - Show = buyer_username, seller_username, gameAd_title(s), gameAd_price(s), orderDate.
