Overview

OmniStudio is a modular system assisting in designing reusable industry-specific solutions on Salesforce. As a result, complex processes are built with significant development time savings.
It includes standard components that make this possible: Flex cards, OmniScripts, OmniStudio DataRaptors, and Integration Procedures.

OmniScripts

This is new declarative tool that can create pixel-perfect, dynamic guided digital experiences embedded in a website or your console, and should be the default option for external personas and industry-specific use cases. It guides users through complicated sales or service processes. A drag-and-drop editor helps you design customer interactions by creating specific sequences with its elements.

You create OmniScripts using an intuitive drag-and-drop editor that enables you to group various elements such as actions (extract data, send email), functions (formulas), input fields, and branching logic. In the end, you get an LWC component that you can deploy and launch from Communities, Object detail pages, and FlexCards.

Data Raptors

In 99% of any business process or customer interaction there is a need to extract data, display data, or save data after the user changes it. DataRaptor provides a configurable (there’s a theme here) service for retrieving, transforming, and updating data.

DataRaptor has three components:
DataRaptor Extract —
Retrieve and transform data from Salesforce. With DataRaptor Turbo Extract (a relatively new offering) you can retrieve data from a single Salesforce object type. It has a simpler configuration and better performance at runtime.
DataRaptor Load —
Transform and save data to Salesforce.
DataRaptor Transform —
Transform any data.

Dataraptor is typically used to provide data to an OmniScript or FlexCard from Salesforce and write updates from an OmniScript or FlexCard back to Salesforce. A DataRaptor or Integration Procedure (covered next) can also auto-generate Apex REST endpoint so it can be invoked from external systems.
