Why should I use an API?
An API is a way to plug in technology that is already built, into your new site. This means there’s no need to build systems from scratch. It’s often cheaper and more secure to use an API, especially when building an e-commerce platform. Some examples of good API’s are Moltin , Big Commerce and Snipcart.
Is there anything I need to worry about?
Not really. Your developer will have built e-commerce websites before, and will know their favourite API’s to integrate and ensure the best experience for your customers. All you need to do is think about how you want to set up your store and what would make sense for your customers - then let your developer do the rest!
