# Testing fetching product identifiers

Verify that your app receives the correct product identifiers by inspecting or replicating your app’s process for retrieving the identifiers.

## Overview

Overview If you embed your product identifiers in your app, set a breakpoint in your code after the code loads the identifiers. Verify that the instance of NSArray contains your expected list of product identifiers. note: Changes that you make to product metadata in App Store Connect can take up to one hour to appear in the sandbox environment. If your app fetches your product identifiers from a server, manually fetch the JSON file using a web browser such as Safari, or a command-line utility such as curl. Verify that the data your server returns contains the expected list of product identifiers and that your server correctly implements standard HTTP caching mechanisms. For more information on fetching product identifiers, see Loading in-app product identifiers.
