Ty Salva, For this I need the premium version or the Free version supports it?
The ATUM API is included with the free version. The premium add-ons add extra endpoints to it though.
Salva, I've checked this with my developer and looking the documentation it only support an integration with another woocommerce base platform. In Our case the stock administration is from an external platform (Not WP or WC). So the thing we are looking for is a query from WC to this external platform of the stocks (Online). Let me know if this explanation is clear for you. Thanks
Sorry. I don't understand what you mean with "it only support an integration with another woocommerce base platform".
This is an API that extends the official WC API v3 (latest version) and can be used to Read/Write/Update/Delete from and to your WooCommerce. So if you need to query something from WC, you can use the API. I don't understand what's the problem.
