Configuring the SDK

Configuration is used by the SDK for rendering UI components with the correct branding and assets, T&Cs, web links, and currency formatting.

For version 2 of Checkout a configuration is required to determine the endpoint and environment. Your configuration should be formed from the configuration API as well as the localization settings of your store. The locale determines the endpoint checkout v2 will use, for locales with a US region the US checkout URL will be used for instance. For environment we recommend using .sandbox in debug and .production for release builds.

For example:

let configuration = try Configuration(
  minimumAmount: response.minimumAmount?.amount,
  maximumAmount: response.maximumAmount.amount,
  currencyCode: response.maximumAmount.currency,
  locale: Locale(identifier: "en_US"),
  environment: .sandbox


You may also choose to send the desired locale and/or environment data back from your own API. This configuration should be cached by your application and an attempt to update it should be made once a day (or a frequency you determine acceptable based on your requirements). It is also recommended to include an initial version matching the live configuration in case the first time load fails.
