Magento2 API update multiple inventory items

Question

I'm developing integration with magento. My client want to update his inventory via REST or API, the problem is that he has thousands of products and it will take a lot of time to update them one by one. I didn't found the way to update many inventory items neither from SOAP nor from REST. (For previous versions i used catalogInventoryStockItemMultiUpdate)

How to update a lot of inventory items in 1 call?

Answer 1

There is no Multiupdate. You would need to create such a Module. However a faster option to update only the stock is this: [PUT] /V1/products/{productSku}/stockItems/{itemId}

If you will develop such a Module, you should also make your code to do something similar to the code behind that call.
