Integrate our Shopify Store with Ongoing Warehouse API

Integrate our Shopify store with Ongoin Warehouse API, Ongoing system shouldn't not pull changed information from Shopify column such as SKUs, Barcode (EAN) so that information of SKUs and EAN at ongoing system should always be the same. Shopify should also be able to detect various carrier services based on weight and forward this information to Ongoin Warehouse 3PL. Example -> Customer pick product that weight 50kg -> Shopify detect that it over 50kg and auto select carrier -> Shopify then send this information to Ongoing warehouse system. - Fulfilled orders must be automatically reported to Shopify as fulfilled. - When a tracking number has been received from the TA-system (e.g. Unifaun) then the order should be reported as fulfilled in Shopify - Tracking numbers should be transferred to Shopify - The customer should be notified about the delivery by Shopify. - The status that the order should have in Shopify to be transferred by the WMS is Order status "open", financial status "authorised" and fulfilment status "unshipped". - Synchronization interval should be real time or close to real time. Changed in Shopify product colum or in the product pages should not be able to change anything at our Ongoing warehouse system. When Order are made and personnel at the warehouse remove the stock from the system only then should Shopify pick up the info and auto change the stock in the Shopify eCommerce platform both frontend and backend We require that API need to be reliable to use and the API connection needs to be QA before release such as Functionality testing, Reliability testing, Creativity testing, Proficiency testing.
