OmniStudio Patterns
Based on Real Implementation Experience: These patterns come from public sector and education implementations using OmniStudio for complex intake and case processes.
Overview
OmniStudio provides:
- OmniScripts for guided, multi-step workflows.
- FlexCards for configurable UI cards that surface data from multiple sources.
This document focuses on when to choose OmniStudio vs LWC or Flow, and on structural patterns for maintainable OmniScripts and FlexCards.
Prerequisites
- Required Knowledge:
- Basic Lightning Experience navigation.
- Understanding of the underlying data model used in the process.

When to Use OmniStudio
Use OmniStudio When
- You need highly guided user journeys with multiple steps and branching.
- Requirements are heavily configuration-driven and likely to change frequently.
- You are integrating data from multiple systems in a single UI.
Prefer LWC or Flow When
- You need lightweight components embedded in record pages.
- Logic is primarily record-triggered and back-end oriented.
- You require fine-grained control over UX and performance beyond OmniStudio’s abstraction.
Core Concepts
OmniScript Design
- Break complex scripts into modular sub-scripts where possible.
- Use DataRaptors and Integration Procedures to abstract data access and transformations.
FlexCard Design
- Keep FlexCards focused (single purpose per card).
- Avoid overloading cards with too many states or actions.
Patterns and Examples
Pattern 1: Guided Intake OmniScript
- Multi-step form capturing data across several related objects.
- Uses DataRaptors to prefill and save data.
- Includes draft-save and resume later when supported.
Pattern 2: Summary FlexCard
- Combines data from multiple related records.
- Provides quick actions (launch OmniScript, open record, start Flow).
Edge Cases and Limitations
- OmniStudio components can have heavier page load than simple LWCs.
- Some advanced behaviors may still require custom LWCs embedded inside OmniStudio.

Q&A
Q: When should I embed a Flow or LWC inside OmniStudio?
A: Embed when you need capabilities not easily modeled in OmniStudio alone (e.g., complex custom validation, performance-optimized UI). Keep OmniStudio responsible for orchestration, while LWC/Flow handle specialized tasks.
