Localization

Message Templates provide localization support out-of-the-box. Message Templates sent to a user will be localized according to the device locale settings. A business can also optionally specify a fallback locale for displaying the message if a translation does not exist.

This document covers:

Localizable Parameters

Some Message Template parameters (e.g., date/time, prices, etc.) should be displayed differently depending on the client's language/locale. See the Localizable Parameters documentation for more information.

If the device is unsuccessful in localizing a parameter, it should fall back to using the HSMLocalizableParameter's default string.
