OmniStudio-Developer Salesforce Certified OmniStudio Developer Plat-Dev-210 Question and Answers

In OmniStudio Integration Procedures, when referencing data from a prior step in the HTTP Action URL, the correct merge code syntax is:

%ElementName.PropertyName%

So, referencing a value called Date from a step named SetValues must be written as:

%SetValues.Date%

This is the format recognized by the OmniStudio Merge Language (OML) for dynamic value substitution in URLs or headers.

Incorrect Options:

A. Invalid syntax – not recognized by OmniStudio merge logic.

B. {{SetValues.Date}} is used in FlexCards, not in Integration Procedures.

D. %SetValues: Date% is incorrect merge syntax due to space and colon use.

Salesforce OmniStudio Documentation → Merge Code Syntax for Integration Procedures

The best available answer is A, but the wording is not perfect. The safe testing pattern is to avoid changing the published cache configuration used by production users. Changing Cache Duration to 0 or disabling the Cache property would alter runtime behavior for everyone using that active Integration Procedure. Changing Type/SubType is also a bad workaround because it changes the component identity and can break callers. A throwaway test input is the least disruptive option because it lets the developer create an isolated request path for testing rather than clearing or disabling shared production cache. In a real implementation, the test value must affect the effective cache signature; if an explicit Cache Key Property is configured and the throwaway value is outside that key, it will not bypass the cached entry.

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

For an active OmniScript, the correct practice is to create a new version, make the change in that new version, test it, and activate it only when it is ready. Editing the active version directly is risky because users can be affected immediately, and in-flight users may experience inconsistent behavior. Cloning creates a separate component and is useful when the new script must be independent, but it is not the best approach for a minor controlled change to the same OmniScript. Waiting for a Salesforce release is irrelevant because this is a configuration lifecycle issue, not a platform-release dependency. Salesforce’s OmniStudio versioning guidance supports using versions so changes can be validated before replacing the active version used by end users.

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

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 best practice for configuring the Input JSON for a DataRaptor Load is to copy the Input JSON from the OmniScript {Data} modal. This ensures that the Input JSON matches the data structure and format of the OmniScript data. The DataRaptor Action Debug node may not have the same data as the OmniScript data, and building the Input JSON node by node in an editor or in the DataRaptor Designer may introduce errors or inconsistencies.

 The Use Data JSON property must be selected in the properties of the Type Ahead Block in order to display the fetched data in the fields. The Lookup Mode property is used to specify the type of lookup to perform. The FirstName, LastName, and BirthDate fields can be placed inside or outside the Type Ahead Block. The typeHead key is in the correct format.

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.

According to the Integration Procedure Actions page, a Remote Action can use a function in an Additional Output value field or in a Remote Options value field. According to the Response Actions page, a Response Action can use a function in an Additional Input value field.

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.

 Checking the Send Only Additional Input checkbox allows the Remote Action element to send only the key/value pairs specified in Additional input to the Apex method. The Additional input should have the same keys as the method parameters, and the values should be set to {{InputData.node}} for each node. For example, AccountId: {{InputData.AccountId}} and ProductId: {{InputData.Details.Products}}.

In OmniStudio, the Invoke Mode: Fire and Forget setting allows an OmniScript to call an Integration Procedure asynchronously, meaning it does not wait for the response to complete before continuing user interaction.

C. Invoke Mode Fire and Forget – This is the correct setting. It’s designed specifically for use cases where the user experience should not be blocked by backend processing.

Incorrect Options:

A. Use Future is not a valid OmniScript configuration option.

B. Invoke Mode Non-Blocking is not an official setting in OmniStudio terminology.

D. Toast Completion is a UI notification setting and does not impact execution behavior.

OmniStudio Developer Guide → Integration Procedure Actions in OmniScripts

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.

Versioning a FlexCard allows the developer to make changes to the FlexCard without affecting the existing instances of the FlexCard. The developer can choose to update all instances of the FlexCard with the new version or keep them as they are. This is useful when the changes are minor and do not affect the functionality or layout of the FlexCard. Cloning a FlexCard creates a copy of the FlexCard with a new name and ID. The developer can make changes to the cloned FlexCard without affecting the original FlexCard. This is useful when the changes are major and require a different configuration or design of the FlexCard1. In this case, since all instances of the FlexCard must be updated with the changes, versioning is the best course of action.

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 Repeatable Mode property on the data table elements allows the developer to display multiple records in a single data table. The Repeat Records feature on the FlexCard Setup tab is used to display multiple FlexCards for each record in a data source. The Record Looping feature on the data table elements is used to iterate over a list of records and perform actions on each record. The Overwrite Target for all Null input checkbox on the Account id field is used to overwrite the existing value in the target object with null if the input value is null.

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 Additional Input property allows the developer to specify additional input parameters to be sent to the Integration Procedure element. The input parameters can be specified as a JSON object or as a list of key-value pairs. If the developer checked Send Only Additional Input, then only the input parameters specified in Additional Input are sent, and the SEND/RESPONSE TRANSFORMATIONS are ignored. Therefore, the developer needs to specify the same input parameters as in the SEND/RESPONSE TRANSFORMATIONS in Additional Input. Option C shows how to do this using a JSON object with two properties: “DBExtractAction:Account” and “DBExtractAction:SecondaryAccount”. The values of these properties are the same as in the SEND/RESPONSE TRANSFORMATIONS. 

The Timeout property on the HTTP Action in the Integration Procedure specifies how long to wait for a response from the external system before throwing an error. The Chain On Step checkbox on the HTTP Action in the Integration Procedure indicates that the next action should be executed only if the current action is successful. These two configurations should be used to implement the call to the external system given its known performance issues. 

The intended answer is C, but the wording is sloppy. A true HTTP 401 normally comes from the external service and usually means authentication headers, tokens, or credentials are rejected. However, OmniStudio/Salesforce outbound HTTP calls also require the target endpoint to be allowed through Remote Site Settings or an equivalent named credential setup. If the API key is confirmed correct and the available choices focus on Salesforce configuration, the most probable platform-side cause is that the external URL is not trusted in Remote Site Settings. API Access permission on the user profile does not authorize an external endpoint. Chainable execution does not cause endpoint authorization failure. Missing Set Values would affect input construction, not Salesforce’s permission to call the URL.

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

A Data Mapper Transform is used to restructure input JSON into the output JSON format required by a target system. Since the target requires a nested array of objects, the developer must map the source value into the correct nested target path so the Data Mapper output structure creates the ContactDetails array and Phone object. A flat direct mapping does not describe the required parent array and child object structure. A Formula is not required just to place an existing source value into a nested output structure; formulas are used when the value itself must be calculated or transformed. Mapping to the root node would lose the required ContactDetails and Phone hierarchy. The correct method is nested target path mapping.

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

After defining a formula, the result must be stored and made available in the Data Mapper output structure. In the current Data Mapper design pattern, the formula result path creates a JSON node, and the developer then maps that result into the final output through the mapping configuration. This is why option B is the best answer: the formula is not useful to downstream actions until it is mapped to the required target output. The Extract tab is used to define source data retrieval, not to map formula results. The Output tab applies to specific Extract-style mappings in older terminology, but the question uses the generic Data Mapper mapping workflow. The essential step is to map the formula result into the JSON.

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

To launch an OmniScript from a FlexCard, the Action element must identify the target OmniScript by its Type, SubType, and related configuration. Because the OmniScript requires the Case ID, the developer must explicitly pass the FlexCard data value, such as CaseId, through the action’s input mapping. Option D is unsafe because the OmniScript does not automatically know which Case ID to use unless the value is passed through context or input parameters. Option B confuses launching the OmniScript with saving Case data; the Data Mapper Load would be used later inside the OmniScript or Integration Procedure. Option C describes a more custom LWC-style configuration, not the standard OmniScript Action setup from a FlexCard.

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

 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 three elements: Step, Block, and Telephone. The Step element is an empty object, the Block element is an object with two properties: Text and Telephone, and the Telephone element is a string. Therefore, the JSON code that correctly represents the step in the OmniScript Structure panel 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.

A DataRaptor Transform can be used to transform data from one format to another, such as JSON, XML, or CSV. The developer can specify the input and output paths for each field in the Transform tab. The developer can also use formulas to manipulate data in the Formula tab1. To transform contact data into a JSON array, the developer can use either of these methods:

Use a formula LIST(Contact), and add the output of the formula as the input in the Transform tab. This will create a list of contact objects from the input JSON and output it as a JSON array.

Set the Input JSON Path as Contact, the Output JSON Path as Contact, and the Output Data Type as List. This will output each contact object as an element of a JSON array.

The Remote Action node is identified by the element name configured in the Integration Procedure. Since the Remote Action is named FetchCart, the relevant Preview JSON node for that action is FetchCart. The debug-specific node, such as FetchCartDebug, is used for diagnostic details, not as the primary action node being evaluated in this question. ResponseCart and ResponseCartDebug belong to the Response Action, not the Remote Action. Salesforce documentation confirms that a Remote Action in an Integration Procedure calls the specified Apex class, method, or invocable action, and Integration Procedure actions are configured and executed as named elements in the procedure sequence.

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

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

A contextual cache key partitions cached Integration Procedure data by the key value. Since the first request used AccountId = 001A, that cache entry is valid only for that contextual value. A later request using AccountId = 001B is a different context, so OmniStudio should not return the 001A response. Instead, the Integration Procedure runs again and creates a separate cache entry for 001B. This is the point of contextual caching: improve performance without mixing data across records or users. Option A is wrong because a new key does not clear the previous key. Option B is wrong because contextual keys are valid cache configuration. Option C would be a serious data leakage issue.

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

The correct answer is A. In a parent-child FlexCard design, attributes are passed from the parent FlexCard to the child FlexCard and referenced in the child using the Parent context variable. Salesforce documentation states that the Parent context variable is used to reference attributes from the parent FlexCard on the child FlexCard, and child FlexCard properties allow passing data from the parent by creating attributes and assigning data merge field values. Therefore, when the postal code is passed as a parent attribute, the child FlexCard should reference it as {Parent.postalcode}. {Params.postalcode} is used for URL or runtime parameters, {postalcode} references local data only, and {attr.postalcode} is not the correct OmniStudio parent context syntax.

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

This scenario relates to FlexCard preview behavior and data mapping issues.

B. There is no Salesforce record for the FlexCard based on the RecordId in the layout ' s Test Data Source Settings – If the test record does not exist, the FlexCard will not display any data during preview. This is a common setup mistake.

C. The Data Node field for the FlexCard is empty – The Data Node field must be set correctly to match the JSON node where the expected data resides. If it is empty or incorrect, the FlexCard won’t bind data to UI elements.

Incorrect Options:

A. Even if the RecordId is from a different record type, as long as the data structure aligns, it would still render; it’s not a definitive reason for the card failing to display.

D. Attributes are not required to display field values directly; they are used for passing data between cards or from context, not for direct field rendering.

Salesforce OmniStudio → FlexCard Data Source Setup & Troubleshooting

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 Output JSON Path is input:BasePrice. The required JSON places BasePrice inside the lowercase input node, so the path must preserve both the correct parent node and the exact field name casing. Option A is wrong because it uses dot notation and incorrectly lowercases BasePrice as baseprice. Option B is wrong because it uses Input with an uppercase I, while the JSON node is input. In JSON-based mappings, path and field names must match the expected output structure. Salesforce’s Data Mapper Transform documentation states that the Output JSON Path defines the desired output path and that path levels are separated using colon syntax, for example Contact:LastName. Therefore, C is the only mapping that correctly targets the BasePrice node under input.

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

A DataRaptor Load Action can be used to retrieve data from a Salesforce object by specifying the object name, fields, and filter criteria. A Lookup Input Element can be used to retrieve data from a Salesforce object by allowing the user to search for a record using a lookup field

Multi-language OmniScripts use Salesforce translation infrastructure and custom labels. In normal Salesforce runtime usage, the language shown to the user is driven by the user’s Salesforce language setting, not simply by the browser language or by a random session variable. The default OmniScript language is only the fallback/base design language; it does not decide which translated bundle is displayed for each user when translations exist. Option A is wrong because a global Session Variable is not the standard translation selector. Option B is also wrong in this context because OmniScript translations are tied to Salesforce language and Translation Workbench/custom-label behavior. Therefore, the user’s Salesforce language setting is the correct controlling source for displayed translations.

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

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.

A DocuSign Envelope Action can be used to create and send a document for signature using a DocuSign template. The developer can specify the template ID, recipient details, and prefill data in the action configuration

 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 Node field for the parent FlexCard should be set to {Records}, which is an array of all the records retrieved by the parent FlexCard data source. This will allow the child FlexCard to access the records and display them in a DataTable.

The verified answer is A, not the mock-highlighted C. FlexCard States display based on conditions configured on the state. For this scenario, the Active, Warning, and Critical states should each have a condition that evaluates the RiskLevel value. For example, Active can evaluate RiskLevel = Low, Warning can evaluate RiskLevel = Medium, and Critical can evaluate RiskLevel = High. At runtime, OmniStudio evaluates the state conditions, and the matching state is displayed. A Set State Action on a button is user-driven and does not automatically evaluate RiskLevel. “Conditional State Logic on the Base FlexCard” is not the precise configuration item used here. A main Block state variable is also not what controls card-level state selection.

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

According to the Transform External Data Unit, the Expected Output JSON should match the Output Path of the DataRaptor Transform. In option D, the Output Path is Current:CityState, which matches the Expected Output JSON. The other options have different Output Paths that do not match the Expected Output JSON. Therefore, the correct answer is D.

A DataRaptor Turbo Extract is a simplified version of a DataRaptor Extract that can retrieve data from a single object without changing the structure of the output data. It is easier to configure because it does not require defining extraction steps or JSON paths. It also has better performance at runtime because it uses a native query engine instead of a custom one

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 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.

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.

OmniStudio best practices dictate that versioning is used when enhancements are required within the same logical flow, while cloning is preferred when the new flow is functionally different and used separately.

B. The new Integration Procedure will be used independently – Correct. Cloning creates an entirely new IP definition, ideal for building a similar but standalone process, rather than altering behavior for an existing process.

Incorrect Options:

A. Using a Cache Block is unrelated to cloning vs. versioning.

C. Replacing stub data does not require cloning; could be done in a version.

D. Chainability does not influence whether you should clone or version.

Salesforce OmniStudio Guide → Cloning vs. Versioning Integration Procedures

 Using two separate Calculation Steps with the Conditional Step property selected allows the developer to specify different formulas based on different conditions. The ISTRUE(isCustomer) and NOT(ISTRUE(isCustomer)) functions are used to evaluate the Boolean variable in the Condition syntax. The other options are either missing the Conditional Step property, using incorrect comparison operators, or using an IF statement instead of separate Calculation Steps.

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: ContactName, ContactPhone, ContactEmail, CaseNumber, CaseSubject, and CaseStatus. The DRGetContactDetails action is a DataRaptor Extract action that retrieves data from the Contact and Case objects in Salesforce. The BlkCases element is a Repeat Block that displays a list of cases related to the contact. Therefore, the JSON from the DRGetContactDetails action that would display all six values correctly shown is option A, which has the following structure:

The other options have different structures that do not match the OmniScript structure shown.

The data action should be placed where the step can retrieve the required data before the user needs to see or use it. Placing the Data Mapper Extract Action on the same relevant step keeps the data retrieval close to the UI elements that depend on it and avoids loading unrelated data globally in the Header. Placing the action after the data usage is obviously too late because the fields or options would already be rendered without the needed values. A Set Values element cannot execute a Data Mapper Extract; it only sets or changes values in the OmniScript data JSON. Salesforce’s OmniScript action-element documentation explains that action elements are used to get, modify, and write data during the OmniScript process.

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

A Sub-Integration Procedure Action lets a parent Integration Procedure call another Integration Procedure, so shared logic can be built once and reused wherever needed. This improves maintainability because future changes are made in the child Integration Procedure instead of being copied manually across many parent procedures. It also supports cleaner modular design: one procedure can handle a specific reusable operation, while parent procedures orchestrate the overall flow. Option A is not the key advantage because asynchronous behavior depends on specific chainable or queueable configuration. Option B is wrong because exception handling may still be required. Option C is not guaranteed, especially when chainable execution is used. The central design benefit is reuse and modularity of server-side logic.

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

A Data Mapper Transform controls output structure through its mappings. If the generated XML is flat instead of nested, the developer should first inspect the target path used in the transform mapping. Nested structures require hierarchical output paths, commonly expressed with path notation that represents parent and child nodes. If the target output paths are configured as flat fields, the transform has no instruction to create the required nested XML hierarchy. Missing formulas would affect calculated values, not the tag hierarchy. A missing root node can cause a different structural issue, but the question says output is generated and specifically flat. The best answer is therefore to correct the target path so the mapping represents the required nested schema.

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

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

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.
