Free Practice Questions for the Salesforce Developer OmniStudio-Developer Exam (2026 Updated)

The first responsible action is to validate the Data Mapper query design before committing to the implementation. Prefilling 15 user-based fields can be efficient, but only if the query is selective, returns only needed fields, and uses appropriate filters. Salesforce’s Data Mapper best practices warn developers to avoid server performance problems and to ensure filtering and sorting operations use indexed fields where possible. A Data Mapper Load is wrong because the requirement is to read current user data, not write data back to the User object. Converting the process to a FlexCard does not solve the prefill query risk. A Formula element cannot query Salesforce records. Therefore, option A is the correct risk-reduction step before development proceeds.

The JSON code correctly represents the step in the OmniScript Structure panel shown. The JSON code has the following properties:

The type is “Step”, which indicates that this is a step element in the OmniScript.

The label is “Step 1”, which matches the label shown in the panel.

The name is “Step1”, which matches the name shown in the panel.

The elements property is an array that contains one element, which is a text field.

The text field element has the following properties:

The type is “Text”, which indicates that this is a text field element.

The label is “Text Field 1”, which matches the label shown in the panel.

The name is “TextField1”, which matches the name shown in the panel.

The value property is an empty string, which indicates that this text field has no default value.

The merge code syntax for accessing a node from an Integration Procedure output is {{ProcedureName:NodeName}}. In this case, the ProcedureName is HTTPGetCaseDetails and the NodeName is CaseData. The % sign is used for single-value merge codes, not node merge codes. The $ sign is used for variables, not merge codes.

 Deleting a row in Version 3 will only affect that version, not any previous or future versions. The row that contains the Code CA-SF will remain in Versions 1 and 2, as well as any versions created after Version 3. The other options are incorrect because they imply that deleting a row in one version will affect other versions as well.

The required SOQL behavior has two separate parts: ORDER BY and LIMIT. Ordering controls the sort sequence, such as sorting Tasks by CreatedDate descending so the newest Tasks appear first. Limit restricts how many records are returned, so setting the limit to five produces only the five most recent records. Filter is used to define matching criteria, such as records related to a specific Contact, but it does not create a LIMIT clause. Output Path controls where returned data appears in the JSON structure, not the query ordering or row count. Therefore, the necessary properties are Limit and Ordering. Salesforce’s Data Mapper configuration guidance confirms that Extracts read Salesforce data, can filter/select returned fields, and support extract configuration properties for returned records.

================

According to Salesforce OmniStudio Integration Procedures documentation, when working with deeply nested JSON, Integration Procedures are ideal. They allow developers to flatten and manipulate JSON data, especially when handling external responses.

C. Integration Procedure – This is correct. IPs provide Response Transformers, DataRaptor Transforms, and Response Actions to reshape and simplify nested data structures for consumption by front-end components.

Incorrect Options:

A. DataRaptor Transform is used inside IPs but cannot directly handle external HTTP calls or manage complex orchestration.

B. HTTP Action Element is used inside an Integration Procedure, but by itself, it does not process or simplify the data.

D. Guided Workflow is not a recognized OmniStudio component for data transformation.

OmniStudio Integration Procedures Guide → Handling Nested JSON

To retrieve (read) data from Salesforce objects:

A. Data Mapper Extract Action – Correct. A DataRaptor Extract is specifically used to retrieve data from Salesforce, based on input parameters or context.

C. Lookup Input Element – Correct. This is used within OmniScripts to look up a record by matching input data, essentially performing a read operation.

Incorrect Options:

B. DataRaptor Post is not a valid DataRaptor type.

D. DataRaptor Load Action is used for writing/updating data, not retrieving it.

Salesforce OmniStudio Guide → DataRaptor Types and Lookup Input Element Usage

The JSON data structure in option C supports the card layout and follows best practices. It has a list of objects, each representing a product, with the properties “ProductCode”, “ProductName”, “ProductDescription”, and “ProductPrice”. These properties match the fields in the card layout. The JSON data structure also follows the naming convention of using camel case for property names. The JSON data structures in options A and B do not match the fields in the card layout and do not follow the naming convention.

In OmniScripts, if you need to apply a function (like COUNTIF) to dynamic data and show the result immediately, the Formula element is the correct choice.

B. Formula element – The Formula element supports real-time calculation using OmniStudio expression functions (like COUNTIF, SUM, etc.) and updates values instantly on the screen without the need for server calls.

Incorrect Options:

A. Set Values element is used to set static or conditional values but doesn’t support formula evaluation.

C. Range element is used for value comparisons and conditions, not for calculations.

Salesforce OmniStudio Developer Guide → OmniScript Formula Element

The correct syntax for the Send JSON Path is ActionName: BlockName, where ActionName is the name of the action element and BlockName is the name of the block element that contains the output data. The other options are either missing the colon or using incorrect names.

The PREVIEW tab in OmniScript allows the developer to test the DataRaptor Extract by providing a record ID and viewing the output data. This is a quick and easy way to troubleshoot whether the DataRaptor Extract is retrieving data correctly.

The LWC PubSub Message flag in the Set Values action of the parent OmniScript enables the parent OmniScript to send data to the embedded OmniScript using a custom event. If this flag is not set, the data will not be passed to the embedded OmniScript.

In OmniStudio Integration Procedures, when you want to reference the output of an element in a nested block (e.g., for use in a Remote Action or another step), you must use dot notation that mirrors the block structure hierarchy.

In the exhibit:

Action1 is nested inside:

BlockB, which is nested inside:

BlockA

Therefore, the correct Send JSON Path to access the result of Action1 is:

CopyEdit

BlockA.BlockB.Action1

This format complies with the standard output reference syntax in Integration Procedures, which follows the pattern:

php-template

CopyEdit

< ParentBlock > . < ChildBlock > . < ActionElement >

Incorrect Options:

B. BlockA:BlockB:Action1 – Uses colons instead of dots. This is invalid syntax in JSON path resolution within Integration Procedures.

C. Action1:BlockB:BlockA – Incorrect order and invalid separators.

D. Action1.BlockB.BlockA – Incorrect order (reversed path).

 The correct syntax for passing all of the parent FlexCard’s records to a child FlexCard is {Records}, which represents an array of records. The other options are incorrect because they either use an invalid syntax or refer to a single record instead of an array of records.

The requirement is only to show or hide a section based on a value already present in the OmniScript data JSON. That is exactly what Conditional View is designed for. It evaluates client-side conditions and controls whether a step, block, or element is displayed, editable, or required. Using an Integration Procedure would add unnecessary server-side processing because the required VIP value is already available in the OmniScript. A Data Mapper Transform is also unnecessary because there is no structural transformation requirement. Creating a new version may be part of the deployment process, but it is not the functional configuration that controls visibility. The best implementation is to place the special offers section in the script and configure Conditional View logic against the VIP member value.

================

The Id Field for Actions in the FlexCard specifies which field from the FlexCard data source will be used as the record ID for the OmniScript. If this field is blank, the OmniScript will not receive any record ID and will not be able to retrieve any Salesforce data. In the DataRaptor Extract Action, the Input Parameters Filter Value determines how to filter the data based on the record ID. If this value is misspelled, the DataRaptor Extract will not be able to match the record ID and will not return any data.

A DataRaptor Transform can simplify nested data by transforming it into a flat structure. The developer can use JSON paths to map the input data to the output data and define the output structure.

The best design is to combine a Loop Block with calculation-oriented actions. A Loop Block iterates over each item in a data array, allowing the actions inside the block to repeat for every element. A Set Values element inside the loop can set intermediate values, reshape nodes , or apply simple formulas per array item. For more complex, multi-step calculation logic, an Expression Set Action is appropriate because it invokes a configured Expression Set and returns calculated results to the Integration Procedure. A Decision Matrix is mainly for table-driven decision lookups, not general multi-step per-item calculation. A List Action can merge or manipulate lists, but it does not perform the required calculation on every array element.

The minimum access is the OmniStudio User permission set license plus the OmniStudio User permission set. This user only executes guided flows; they do not build or modify OmniScripts, FlexCards, Data Mappers, or Integration Procedures. Assigning OmniStudio Admin would over-permission the user because Admin access is intended for users who create and manage OmniStudio components. A developer permission set would also be excessive and is not the minimum runtime configuration. A PSL alone is not enough because it entitles the user to the feature set, while the permission set grants usable permissions. Salesforce permission guidance states that users must have the appropriate OmniStudio permission set assigned, and the OmniStudio User assignment is appropriate for runtime users rather than designers/admins.

According to the Troubleshoot Flow Errors page, one way to troubleshoot errors is to “check the debug logs for the community”. Another way is to use the Action Debugger tool, which “lets you test and debug actions in OmniStudio”. 

 According to the OmniStudio Developer Guide, “To upsert a record, select the Upsert Key checkbox for the field that contains the unique identifier for the record. If you want to create a new record when no match is found, select Is Required for Upsert.” Therefore, the correct answer is B.

According to the OmniStudio Developer Guide, “DataRaptor Transform actions can convert JSON to XML and vice versa.” Therefore, the correct answer is C.

The Conditional View property on the Step elements is the correct client-side control. The branching depends on a value selected earlier in the OmniScript, and the constraint explicitly says not to use server-side logic. Conditional View can hide or show elements, blocks, or steps based on conditions in the OmniScript data JSON. Pub/Sub on FlexCard elements is unrelated because this is an OmniScript step-visibility problem, not inter-component messaging. An Integration Procedure conditional block would push the path decision to server-side logic, violating the requirement. A Data Mapper does not control UI step visibility. Salesforce documentation states that Conditional View hides an element or group of elements in a block or step based on specified conditions, which fits this scenario precisely.

================

FlexCards support embedding a custom Lightning web component through the Custom LWC element. The developer should drag the Custom LWC element onto the FlexCard canvas and configure the component name so OmniStudio knows which Lightning web component to render. Using an HTML element with an lwc tag is not the supported declarative method and can create security, rendering, and maintenance problems. An Action element is used to trigger behavior such as launching flows, OmniScripts, or navigation, not to host an LWC visually inside the card. Option D is also wrong because the configuration does not point to a “Card” property for the Lightning web component. The required implementation is the Custom LWC element with the component name configured.

================

A Remote Action is the Integration Procedure element designed to call custom Apex logic. This scenario requires execution of an Apex method that performs custom authentication and token generation before later data retrieval, which is exactly the type of server-side custom logic handled by a Remote Action. A Data Mapper Transform restructures data; it does not execute Apex. A Sub-Integration Procedure calls another Integration Procedure, not an Apex method directly. An HTTP Action calls an external REST endpoint, which is useful after token generation but does not execute local Apex code. Salesforce documentation explicitly states that the Remote Action element calls the specified Apex class and method or an invocable action.

================

According to the OmniScript Data JSON page, the OmniScript structure JSON defines the data elements and their properties that are used in an OmniScript. The exhibit shows an OmniScript structure JSON with six elements: AccountName, AccountNumber, AccountType, AccountOwner, ContactName, and ContactPhone. The DRGetAccountDetails action is a DataRaptor Extract action that retrieves data from the Account and Contact objects in Salesforce. The BlkContacts element is a Repeat Block that displays a list of contacts related to the account. Therefore, the JSON from the DRGetAccountDetails action that would display all six values correctly in the OmniScript structure shown is option C, which has the following structure:

{ The other options have different structures that do not match the OmniScript structure shown. Therefore, the correct answer is C.

Seed Data JSON inserts static launch-time values into the OmniScript data JSON. These values are not stored under a node named “Script Configuration”; that is only where the developer configures the seed data in the designer. At runtime, the seeded key/value pairs are placed into the OmniScript’s data JSON under the seed structure, so the correct representation is option B. This is useful when an OmniScript must start with hidden or prefilled values before any user interaction occurs. Salesforce documentation explains that the Seed Data JSON property is used to prefill OmniScript fields or add hidden nodes to the OmniScript Data JSON during initial load.

================

Option C is the correct way to configure Additional input to send exactly the same data as Input Data. The Additional input should have a key/value pair for each field in Input Data, and the value should be set to {{InputData.field}} for each field. This will pass the value of Input Data for each field to Additional input.

QUESTIONNO: 23

A healthcare company wants to enable its subscribers to add, edit, or delete dependents related to their policy Community portal. The developer on the project decides to use an MniScript.

How should the developer configure the OmniScript to providethis functionality?

A. Use an Edit Block element configured with Remote Actions.

B. Use an Edit Block element configured with SOQL statements.

C. Use an Input Block element and a DataRaptor Post Action element.

D. Use a Text Block element and a Remote Action element.

Answer: A

An Edit Block element configured with Remote Actions allows the developer to create a dynamic table that can display, add, edit, or delete records from a Salesforce object. The Remote Actions can be configured to perform CRUD operations on the object using SOQL or Apex.

 The Send JSON Path syntax for accessing an element from an Integration Procedure structure is BlockName.ElementName. In this case, the BlockName is BlockX and the ElementName is ActionZ. The colon (:) is used to separate the input and output parameters, not the block and element names. The order of the block and element names should follow the hierarchy of the structure, from top to bottom. The Additional input parameter is not needed in this case, as it is already included in the Send JSON Path.

An Integration Procedure that calls a Remote Action depends on the referenced Apex class existing in the target org. If the Apex class is missing, the Integration Procedure cannot resolve that dependency during deployment or execution. The required fix is to deploy the Apex class first, then deploy the Integration Procedure that references it. Cache Duration has no relationship to metadata dependency resolution. Chainable configuration controls long-running transaction behavior and governor-limit handling, not missing Apex metadata. A Try-Catch Block can help handle runtime failures, but it does not solve a deployment failure caused by an absent Apex class. Salesforce’s OmniStudio deployment guidance specifically includes considerations for Apex class checks and dependencies when deploying Integration Procedures.

The input JSON paths In the DataRaptor Load must match the JSON from the OmniScript, otherwise the data will not be mapped correctly to the Salesforce fields. ContextId must be spelled correctly in the merge code that passes the Recordld to the DataRaptor, otherwise the DataRaptor will not be able to identify which record to update. The fields that are not updated are not necessarily read only in Salesforce, as they could be editable by other means. In the DataRaptor Load, in the Preview tab, the Record is from the wrong record type has no effect on updating data in Salesforce, as it is only used for testing purposes.

A Data Mapper Extract Action is the correct choice when an OmniScript must retrieve many fields from a Salesforce record. Data Mapper Extracts are built specifically to read Salesforce data, select the required fields, apply filters, and return the data in JSON, XML, or another configured output structure. A Lookup element is appropriate for retrieving or selecting a single record or field value, but it is not the best tool for pulling many fields. HTTP Action is for calling external HTTP endpoints, not directly querying Salesforce records. Select is a user-input element, not a Salesforce data retrieval tool. For a multi-field Salesforce record retrieval requirement, Data Mapper Extract provides the correct declarative query and mapping capability.

================

An OmniScript and a Child FlexCard are both valid components that can be embedded in a flyout. An Integration Procedure and a DataRaptor are not components, but actions that can be performed within an OmniScript or a FlexCard.

The strongest listed choice is a Try-Catch Block, but the real implementation must also use Rollback On Error in the Integration Procedure configuration. Salesforce’s OmniStudio training states that Rollback On Error commits database changes only if the entire transaction completes successfully; otherwise, intermediate database changes are rolled back. A Try-Catch Block is used to run steps and catch failures, and with failure handling configured correctly, the failed block can return a controlled error response. A generic Group element only organizes or conditionally runs steps; it does not provide rollback by itself. Chainable processing intentionally splits work into separate transactions, which is the opposite of the requirement. Continue on Error only addresses Data Mapper behavior, not full transaction integrity.

================

The correct answer is JSON. Vlocity Build Tool, also called the OmniStudio Build Tool in newer documentation, exports and deploys OmniStudio/Vlocity DataPacks in a source-control-friendly structure. A Data Mapper, FlexCard, OmniScript, or Integration Procedure is represented as DataPack metadata, and the component definition is stored in JSON-based files, while job or manifest configuration can use YAML. DOCX is a document format and has no role in OmniStudio deployment metadata. CSV can hold tabular data, not a full component definition. XML is used in some Salesforce metadata contexts, but DataPacks for OmniStudio deployment are not typically represented as XML component files. Therefore, JSON is the correct deployment metadata format.

================

The correct answer is Option B, which shows a FlexCard with a header, a body, and a footer. The header contains the title and the icon of the FlexCard. The body contains a Data table element that displays the records from the parent FlexCard. The footer contains a navigation Action that invokes an OmniScript. Option A is incorrect because it shows a FlexCard with only a header and a body, and no footer.

Cloning an Integration Procedure creates a copy of it that can be modified and used independently from the original one. This is useful when the new Integration Procedure has a different purpose or functionality than the original one

OmniScript is the correct tool because the scenario describes an end-to-end guided business process: collecting property details, applying conditional steps, calling calculation logic, and submitting the final application. Integration Procedures are excellent for server-side orchestration, integrations, and calculations behind the scenes, but they do not provide the user-facing guided interaction by themselves. Data Mappers retrieve, transform, or save data; they are not the process UI. FlexCards display contextual information and actions but are not designed as the primary multi-step application workflow. Salesforce describes OmniScripts as guided, interactive processes that help users complete business tasks and collect data across channels. Therefore, the core component controlling this process is an OmniScript.

Checking the Enable Cancel checkbox in the Setup tab under Cancel Options allows the developer to enable the cancel functionality for all steps in the OmniScript. The user can cancel the OmniScript at any time by clicking the Cancel button in the top right corner of the OmniScript. Adding a navigation Action inside each step is not necessary and would clutter the OmniScript design. Setting the Component name or Element Name to ‘’Cancel’’ has no effect on enabling the cancel functionality.

The correct answer is D. Data Mapper Turbo Extract, based on best practices in the official OmniStudio documentation.

From the OmniStudio Developer Guide → DataRaptors → Turbo Extract:

DataRaptor Turbo Extract is a lightweight, high-performance extract designed specifically for retrieving data from a single Salesforce object, where no data transformation or complex joins are required.

It is recommended over DataRaptor Extract for performance reasons when only one object and minimal transformation is needed.

Why not the others?

A. DataRaptor Load is used for writing data to Salesforce, not retrieving.

B. DataRaptor Transform is used when you need to transform data, not simply extract it.

C. DataRaptor Extract can be used, but Turbo Extract is preferred for the use case of single object, no transformation — per best practices.

Salesforce OmniStudio Developer Guide → DataRaptor Turbo Extract Best Practices

OmniStudio Certification Study Guide → " When to use Turbo Extract "

The Data Node field for the FlexCard is required to specify which data source will be used to populate the FlexCard. If it is empty, the FlexCard will not display any data. The Record Id in the Test Data Source settings is used to preview the layout with a specific record. If there is no Salesforce record for that Record Id, the FlexCard will not display any data either.

A FlexCard is the correct user-interface component for displaying summarized, contextual, responsive information from one or more data sources. The scenario is not asking for a guided form or step-by-step process; it asks for a single-page health summary with list-like lab results and interactive display behavior. An Integration Procedure can absolutely be used behind the FlexCard to aggregate Salesforce demographic data and EMR lab results, but the component that displays and manages the responsive interaction is the FlexCard. A Data Mapper Extract only retrieves Salesforce data and does not handle external EMR data or UI interaction. OmniScript is better for guided data collection and process automation, not a compact summary card. Therefore, the front-end OmniStudio component should be a FlexCard.

================

The correct design is to call the second Integration Procedure as a Sub-Integration Procedure and enable chainable execution. Chainable Integration Procedures are specifically used to split long-running processing into multiple transactions to avoid Salesforce governor limits. A plain Sub-Integration Procedure Action promotes reuse, but without chainable configuration it does not necessarily create the separate transaction behavior required here. An HTTP Action is for making HTTP callouts, not the cleanest way to invoke internal OmniStudio transaction chaining. A Set Values element only changes data JSON values and cannot execute another Integration Procedure. Because the requirement explicitly says separate transaction context and governor-limit prevention, chainable execution through the Sub-Integration Procedure call is the best answer.

================

 The merge code syntax for passing data from a DataRaptor Extract Action to an HTTP Action is %DataRaptorName: NodeName%. In this case, it is %DRReadCase: CaseNumber%.

The FlexCard Player component is used to display FlexCards in a community page. The developer needs to add the FlexCard’s API name to the FlexCard Player component to configure the FlexCard for deployment in a community.

The child OmniScript must receive specific nodes from the parent OmniScript’s data JSON, so the developer should pass them through Additional Input key/value pairs on the child OmniScript element. Additional Input is used to pass named values into an action or embedded component when the child process needs specific data from the current script context. ContextId would pass only a record identifier, not full Address and Contact JSON nodes. PreFill is used to populate data into an OmniScript, but the question asks which property on the child OmniScript element should be used to pass parent nodes. LWC Component Override is unrelated because it replaces rendering behavior rather than mapping parent script data. Therefore, Additional Input is the correct configuration.

================

The correct tool is the Test Data and Parameters panel in the FlexCard Designer. The requirement is specifically to test the FlexCard directly in its designer with different JSON inputs before deployment. The OmniScript Test Console is for OmniScript logic, not FlexCard data rendering. IDX Workbench is a migration/deployment tool, not the FlexCard’s built-in data-testing panel. A Data Mapper Turbo Extract preview only tests the Data Mapper query output; it does not validate how the FlexCard processes different JSON structures and renders states, fields, or conditional elements. Salesforce documentation for FlexCard testing describes adding test parameters in the FlexCard Designer and previewing/debugging the card using those values, which directly supports option C.

================

According to the OmniStudio DataRaptor Extract documentation, if a developer wants to limit the number of records returned, the best way is to set the " Limit " property on the element or action that is calling the DataRaptor, such as in an Integration Procedure or OmniScript Action.

A. Set the Limit property on the action that calls the Data Mapper Extract – This is the correct method. The calling context (e.g., OmniScript Action or Integration Procedure) includes a property for setting the limit on query results, which is a recommended and clean method to ensure only one record is retrieved.

Incorrect Options:

B. There is no " LIMIT " clause within the DataRaptor Extract definition UI or JSON definition itself.

C. Custom Output Type controls the structure, not the quantity of output.

D. The Filter function applies conditional logic, not record count.

Salesforce OmniStudio Developer Guide → DataRaptor Extract Configuration

The Target property in publishing Options determines where the FlexCard will be displayed. Setting it to the Community page will make the FlexCard available in the community

The correct answer is D, but with one serious qualification: the Data Mapper must be configured with the proper security controls. Data Mapper Load is the OmniStudio component used to write JSON, XML, or custom input data to Salesforce objects. For secure storage, the save operation should rely on Salesforce object access, field-level security, sharing, and OmniStudio security settings rather than storing sensitive values in temporary session variables or assuming the UI framework handles everything automatically. Validation rules help data quality, not full access control. Session Variables are not the correct place to persist sensitive business data. Therefore, Data Mapper Load is the correct saving mechanism, supported by Salesforce security configuration.

================

The Debug Console, or Test Panel, is the correct browser-based tool for testing OmniScript logic and data integration during development. Salesforce CLI and Vlocity Build Tool are deployment or source-control tools; they are not the interactive runtime testing panel inside the OmniScript Designer. Developer Console can inspect Apex and logs, but it is not the built-in OmniScript testing interface. The OmniScript designer preview/debug capability lets the developer execute actions, inspect action requests and responses, and verify how data moves through the script before deployment. Salesforce documentation specifically describes opening the Action Debugger from Preview to view and debug action request and response data, which directly matches the requirement to test script logic and integration behavior.

================
