Which online store management system is best for integrating with an external API?

Question

API

Good afternoon, ladies and gentlemen!
The essence of the question is this. There is a very large domestic software distributor that provides APIs to its partners. This API allows resellers to trade software through their online store, uploading prices, product descriptions and other data directly from the distributor. The purchase (key) after the payment and verification is also issued via the API. According to this model, the online store itself acts, roughly speaking, as a layer between the client and the supplier. The product is not stored in the database of the store.
I wanted to ask if there is a sufficiently flexible system that would allow using the API in such a scheme?
I perfectly understand that you can’t do without outside help, but I would like to understand for a start: do you need a store completely written from scratch, or is it possible to use a certain system, finalizing it?

Answer 1

because of CRUD and other routines, no one writes from scratch
, you can modify anything, stupidly proxy - we take it from here, put it here (in the store database), well, there are modules from all sorts of providers
you are looking for which one is easier to maintain - progers are more accessible, etc.
