WooCommerce Stock Management can be easy when you have digital products or products that are by your side, which you store. But what if the products are stored somewhere else, at a wholesaler or some other service? You will need to get the stock level from the service. In this tutorial, we will look into how this can be done.
This tutorial will just show a way on how you can do that but since there are many services and they are all different, I won’t be getting into how to create a complete solution for it but rather show you a guideline on how you can do that.
At the bottom of this tutorial you will also see two videos that I have recorded for this tutorial.

WooCommerce provides hooks to create the fields on various sections. For making the WooCommerce Stock Management easier, we want to hook our field into the inventory section. Here is the hook which we can use:
Inside that hook, we have a function that should create a WooCommerce field. For various field functions, you can view the file at
For the ID we can use the function
woocommerce_wp_text_input( $args ).
You also need a way to save the ID of our Product. We can do that by hooking into:
I have also create two short videos for this also which you can view on my channel or here:
The code that you have seen here and much more (functions, api connection example) can be read in my eBook:
