API Conventions for Alexa Conversations
If you're interested in localizing your skill to
ja-JP, please sign up at Alexa Conversations Interest.
Alexa Conversations elements, such as annotated dialogs and response templates, use the following conventions.
Variable and type names can start with a letter or an underscore, and can be composed of any alphanumeric characters, as well as the underscore (
_) and hyphen (
-). To maintain readability and consistency, Alexa Conversations adheres to the following convention for the naming of variables, types and members of types, and response templates within our example mark-up use cases. This convention isn't mandatory.
- camelCase for variables/arguments
- PascalCase for types
- _camelCase for type members/properties
- snake_case for response templates
Referencing variables in conversations
Annotated dialogs use the following operators to reference variables from the current dialog state and to guide the Alexa Conversations model to select the correct values for API calls.
- The dot operator (
.) is the separator for accessing the properties of a custom slot type.
- Brackets (
) with an index indicate a particular element of a list. The index of the first element of the list is 0. For example,
$items._quantityrefers to the quantity of the first item in the list.
