I'm building a REST API / SDK for a Full Stack JavaScript platform of boat booking, vessels management, but I don't know which Developer API I should use.
I'm doing it in JavaScript, with Angular, Firebase, Node.js and Paypal buttons.
There's an npm library in Angular that creates orders when we hit a button, but I think I shouldn't use this API because it's not for someone building a platform selling services, but DIGITAL_GOODS or PHISICAL_GOODS.
Also not for selling services from other buyers, i.e. I'm the Software Engineer, I don't have anything to offer, but my customers do. The users should buy it from them on my platform.
