How To Find a Shopify Collection ID

1. From your Shopify admin, go to Products > Collections.
2. Click the collection you want to find the ID for. 
3. Examine the URL in your browser's address bar. Your URL should be similar to the following URL example:

https://my-shop-name.myshopify.com/admin/collections/123456789	

The number after /collections/ is the Collection ID number. In this example, the Collection ID is 123456789.
