# StoreKit external purchases or offers entitlement An entitlement that enables a qualifying app to offer external purchases within app or at a website, in specific regions. ## Discussion This entitlement enables a qualifying app to offer external purchases within the app or at a website of its choice, in specific regions. If your account receives this entitlement, you can add it to your app by opening the project’s `.entitlements` file in Xcode. Then, add a key named `com.apple.developer.storekit.custom-purchase-link.allowed-regions`, followed by an array that enumerates the two-letter ISO-3166-1 country codes for the allowed regions. The example below describes an entitlement that includes Brazil and Japan as the allowed regions that the app supports. ``` com.apple.developer.storekit.custom-purchase-link.allowed-regions br jp ``` > Important: Provide the regions where you intend to offer this functionality. This must only include regions where Apple supports custom purchase link options. In addition to Brazil (br) and Japan (jp), the permitted EU country codes include: Austria (at), Belgium (be), Bulgaria (bg), Croatia (hr), Cyprus (cy), Czechia (cz), Denmark (dk), Estonia (ee), Finland (fi), France (fr), Germany (de), Greece (gr), Hungary (hu), Ireland (ie), Italy (it), Latvia (lv), Lithuania (lt), Luxembourg (lu), Malta (mt), Netherlands (nl), Poland (pl), Portugal (pt), Romania (ro), Slovakia (sk), Slovenia (si), Spain (es), Sweden (se).
