Synchronize products between two separate instances

Hi,

I would like to know what are the options for synchronizing stock quantities between two instances of nopCommerce.

Basically, I do have separate webshops A and B with two databases with the same products in it.
In webshop A, I will add new products. I want these to be automatically available in webshop B as well after saving the new product in webshop A.

When in webshop B, a product is sold, I want webshop A to be notified of the sale and I also want the stock quantity to be corrected in shop A as well. I also want this working the other way. If A sells a product, then B should be notified and the stock quantity should be updated.

Currently, I thought of starting with the nopCommerce API Plugin in which I managed to do api calls from the client application using oauth2.

However, I was wondering if this is the right way to go?
Are there other and better options to be aware of?

Many thx in advance for your reply.

T.
