# Product Dictionary Keys

Keys for identifying products and the tokens for affiliates and campaigns.

## Discussion

These dictionary keys are used in the parameter for the [`loadProduct(withParameters:completionBlock:)`](/documentation/StoreKit/SKStoreProductViewController/loadProduct(withParameters:completionBlock:)) method.

The [`SKStoreProductParameterITunesItemIdentifier`](/documentation/StoreKit/SKStoreProductParameterITunesItemIdentifier) key represents the product to display, and is always required. Other keys provide optional affiliate or promoted product information.
