I want to integrate ETSY on my inventory management project but after little research I got to know that it didn't manage stock of variants for configurable product. It manages stock of overall product, not of its particular variant.
Now I am very curious how etsy seller manage stock particular variant?
Is there any way I can manage stock of my particular variant in etsy?
No, you cannot manage stock for a particular variant.
If it is really important you don't sell more than you have on stock (lots of time to make or impossible to reproduce) then it's best to make a different listing - this also has the advantage of SEO (you can add different keywords from the other variant).
