If you’re preparing for an OmniStudio developer, consultant, or architect role, these basic interview questions and answers will help you build strong foundational knowledge.
1. What is Salesforce OmniStudio?
Answer: Salesforce OmniStudio is a low-code toolset within Salesforce Industries that enables developers and consultants to design guided user flows (OmniScripts), dynamic UI components (FlexCards), and scalable data integrations without writing extensive Apex code. It is optimized for industry-specific business processes.
2. What is OmniScript?
Answer: OmniScript is a step-by-step guided UI that collects user input and executes backend logic such as data fetch, validation, and updates.
3. What is FlexCard?
Answer: A FlexCard is a UI component in Salesforce OmniStudio used to display data in a structured, responsive, and reusable card-based layout. It can show data from Salesforce objects, Integration Procedures, or DataRaptors and is commonly used in Lightning Experience, Communities, and OmniScripts.
4. What is an Integration Procedure?
Answer: An Integration Procedure is a server-side OmniStudio component used to fetch, transform, and send data between Salesforce and external or internal systems without writing Apex code.
5. What is DataRaptor?
Answer: DataRaptor is an OmniStudio component used to extract, load, update, or transform Salesforce data. It provides a declarative way to handle data operations without writing Apex code.
6. Types of DataRaptors?
- Extract
- Load
- Transform
- Turbo Extract
7. What is Turbo Extract?
Answer: Turbo Extract is a high-performance DataRaptor designed for simple, single-object queries.
8. What is OmniStudio Designer?
Answer: A unified interface to design OmniScripts, FlexCards, and Integration Procedures.
9. Difference between OmniScript and Flow?
| OmniScript | Flow |
|---|---|
| UI-centric | Automation-centric |
| Used for guided industry processes | Used for backend and UI automation |
| JSON-based data handling | Variable-based |
| Requires Industries license | Available in standard Salesforce |
| Better for complex guided UI | Better for backend logic |
10. What is Cache in OmniStudio?
Answer: Caching in OmniStudio stores data temporarily at the server level to improve performance and reduce repeated API or database calls, especially in Integration Procedures.
11. What are the main OmniStudio components?
- OmniScript
- FlexCard
- Integration Procedure
- DataRaptor
12. Difference Between LWC and FlexCard
| Aspect | Lightning Web Component (LWC) | OmniStudio FlexCard |
|---|---|---|
| Type | Code-based UI framework | Low-code / No-code UI component |
| Developed Using | JavaScript, HTML, CSS | Configuration (UI designer) |
| Skill Required | Strong coding knowledge | Minimal coding knowledge |
| Performance | Very high (native framework) | High, optimized for UI |
| Customization | Unlimited | Limited to supported features |
| Backend Calls | Apex, REST APIs | Integration Procedures, DataRaptors |
| Reusability | High (custom components) | High (cards & child cards) |
| Development Speed | Slower | Faster |
| Maintenance | Code maintenance required | Easy to maintain |
| Best For | Complex logic & custom UI | Data display & guided UI |
| Responsive Design | Manual handling | Built-in responsiveness |
| Debugging | Developer Console, VS Code | OmniStudio Debugger |
| Deployment | SFDX, Metadata API | OmniStudio Data Packs |
13. Difference between Extract and Turbo Extract
| Extract | Turbo Extract |
|---|---|
| Multiple objects | Single object |
| Complex queries | Simple queries |
| Slower | Faster |
| Flexible | Limited |
14. What are the main components of a FlexCard?
Answer: The main components of a FlexCard are:
- Styles – Control look and feel
- Data Source – Defines where the data comes from
- States – Control different views of the card
- Fields – Display individual data elements
- Actions – Buttons or links for user interaction
15. What data sources can a FlexCard use?
Answer: A FlexCard can get data from:
- Parent OmniScript
- Salesforce Objects
- Integration Procedures
- DataRaptors (Extract)
- Static JSON
16. What is a State in a FlexCard?
Answer: A State represents a specific view or layout of a FlexCard. Multiple states can be created to show different data views, such as summary view, detail view, or edit view, and can be switched using actions.
17. Can we use conditional visibility in FlexCards?
Answer: Yes, FlexCards support conditional visibility using expressions. Fields, actions, or entire states can be shown or hidden based on data values.
18. Can FlexCards be reused?
Answer: Yes, FlexCards are reusable components and can be deployed across multiple pages, apps, and OmniScripts.
19. What is the advantage of using FlexCards?
Answer: FlexCards provide:
- Faster development
- Low-code UI
- Reusability
- Consistent design
- Easy integration with backend services
20. What are the best practices for FlexCards?
Answer:
- Use Integration Procedures for complex logic
- Keep cards lightweight
- Reuse child cards
- Use states instead of multiple cards
- Apply conditional visibility carefully
21. Difference Between OmniScript and FlexCard
| Aspect | OmniScript | FlexCard |
|---|---|---|
| Purpose | Guided user interaction | Data display |
| Type | Process-driven UI | Card-based UI |
| User Input | Yes (forms, steps) | Limited / Mostly read-only |
| Logic Handling | Supports complex flow logic | Very limited logic |
| Data Processing | Integration Procedures, DataRaptors | Integration Procedures, DataRaptors |
| Navigation | Step-by-step | Click-based |
| Validation | Strong validation support | Basic / conditional visibility |
| UI Structure | Steps and blocks | Cards and states |
| Best For | Business processes | Dashboards & summaries |
| Reusability | High | High |
| Mobile Friendly | Yes | Yes |
| Deployment | OmniStudio Data Packs | OmniStudio Data Packs |
22. Difference Between OmniScript and LWC
| Aspect | OmniScript | Lightning Web Component (LWC) |
|---|---|---|
| Type | Low-code guided UI | Code-based UI framework |
| Purpose | Business process orchestration | Custom UI & logic |
| Development | Configuration-driven | JavaScript, HTML, CSS |
| User Interaction | Step-by-step forms | Any UI interaction |
| Logic Handling | Configuration-based rules | Full JavaScript logic |
| Backend Integration | Integration Procedure, DataRaptor | Apex, REST |
| Validation | Built-in validations | Custom validations |
| Reusability | High | Very high |
| Customization | Limited | Unlimited |
| Performance | Good | Excellent |
| Debugging | OmniStudio Debugger | Browser DevTools, VS Code |
23. Why do we use Integration Procedures?
Answer: We use Integration Procedures to:
- Improve performance
- Reduce Apex code
- Orchestrate multiple backend calls
- Apply business logic

- Remote Action
- Integration Procedure Action
- Loop Block
- Set Values
- Conditional Block
25. What is a best practice for Integration Procedures?
Answer:
- Keep IPs small and reusable
