Connect REST API Features | Connect REST API Developer Guide

Action Links
An action link is a button on a feed element. Clicking an action link can take a user to a Web page, initiate a file download, or invoke an API call to Salesforce or to an external server. An action link includes a URL and an HTTP method, and can include a request body and header information, such as an OAuth token for authentication. Use action links to integrate Salesforce and third-party services into the feed so that users can drive productivity and accelerate innovation.

Customer Asset Lifecycle Management
Use Customer Asset Lifecycle Management resources to make lifecycle-managed asset data available for sales and account reps to view in Lightning Experience.

Experience Cloud Sites
Salesforce Experience Cloud lets you create branded digital experiences to share information and collaborate with people who are key to your business processes, such as customers, partners, or employees. Whether you call it a portal, help forum, support community, or something else, an Experience Cloud site is a great place to connect with the important folks in your life.

Feeds and Feed Elements
A feed is a container of feed elements. Feed elements can be feed items, such as specific posts, or generic feed elements, such as bundled posts or recommendations in the feed.

Recommendations
Salesforce provides several types of recommendations, and Connect REST API supports Einstein Next Best Action, custom recommendations for Experience Cloud sites, and Chatter recommendations.

Salesforce Files
