 **Make as few calls as possible; request only information that your app requires to function.**
 
-When interacting with a resource on a store, consider how many calls it takes to accomplish the goal. When you fetch information, investigate whether you can use a bulk endpoint instead of retrieving resources one by one. If possible, use the bulk endpoint and filter the data to retrieve only what you need. For example, the [REST Catalog API](/docs/rest-catalog/products) contains both [Get a product](/docs/rest-catalog/products#get-a-product) and [Get all products](/docs/rest-content/pages#get-pages). If your app or storefront requests one or more products, you can use [Get all products](/docs/rest-content/pages#get-pages) and filter which products you'd like to retrieve using the `id:in` query parameter.

 The same principle applies to bulk endpoints. The base number of resources returned from a bulk request is 50. If you need to retrieve 5,000 products, the default response pagination limit requires you to make 100 API calls to the bulk endpoint. Instead, you can use query parameters to set the response limit to 250 and request the same information in 20 calls.

The initial testing process and delta migration will look very similar to those steps in the products migration process, so you can refer back to them as needed.
