OS23: HOW TO USE APEX REST IN FLEX CARD || FLEX CARDS || OMNISTUDIO
In this session, we explore how to use Apex REST as a data source in Salesforce OmniStudio FlexCards. Unlike Apex Remote, which is used internally within Salesforce, Apex REST is ideal when you need to expose your Apex logic to external systems via REST APIs. We start by understanding the key differences between Apex Remote and Apex REST, and why Apex REST is the right choice when building publicly accessible APIs from Salesforce.
The tutorial then walks through the process of creating an Apex class with the @RestResource annotation, using a URL mapping to define the REST endpoint. In this example, we create an endpoint to fetch a list of Accounts using a simple SOQL query. The class uses @HttpGet to expose a GET method, and returns a list of Account records with fields like Id, Name, and AnnualRevenue.
This video not only demonstrates how to connect FlexCards to Apex REST APIs, but also gives a practical explanation of how external systems could interact with Salesforce through these exposed endpoints. It's a great starting point if you're building digital front-end experiences in Salesforce and want to integrate real-time data from Apex into your UI.
