Moltin, a great service to consider for creating E-Commerce
I have not personally used Moltin, however, based on my intraction with it so far it looks like a good service to consider when building an E-commerce platform. It is designed to take stress away from creating E-Commerce sites by letting the programmer focus on the creative and fun parts.
So what service do they actually provide? Well they allow you to configure everything, e.g. add categories to databases via UI on their site. Then later you can access it as an API call, so any data stored can be retrieved using a provided API. Database management and API creation is no longer your concern. Neither is the security and compliances for that matter, free account has 30, 000 API per month which is more than enough to get started with.
