# Terminology ## Action *Action* in the Session API context means fetching recommendations for a specific view. For example when a visitor navigates from the front page to a product view you would most likely fetch recommendations related to a [product](/techdocs/apis/frontend/implementation-guide-session-api/spa-basics-tracking-events.md#upon-viewing-a-product). This would be considered as an *Action*. Setting the [cart contents](/techdocs/apis/frontend/implementation-guide-session-api/spa-basics-managing-sessions.md#setting-the-cart) however would not be considered as action. It's also good to keep in mind that each *Action* is considered as a page view in Nosto's analytics. It's recommended to perform an action only once per route change to keep the analytics consistent and comparable to traditional "static" e-commerce stores. ## Route change *Route change* in the context of this documentation means, as it stands, when the navigational route (url) of the application is changed. In traditional web sites this would be a (full) page load. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
