I am trying to develop a clover app where I would like to charge merchants on purchase of certain supplies. The app itself will be free and they will only be charged when they buy via the app. Instead of integrating a solution like stripe to charge the merchant I was wondering how I can charge the merchants via Clover. I was reading about the Ecommerce API but that seems to pay the merchant that has the app installed and not the developer. Is this use case possible and if so how?
