Free Practice Questions for Salesforce OmniStudio-Developer Exam

OmniStudio does not natively support direct JSON-to-XML transformation using DataRaptors. When a transformation to specific XML formats is needed for integration with external web services, it is recommended to use Remote Actions that invoke custom Apex classes.

A. Use a Remote Action that calls the XMLStreamWriter class – Correct. The XMLStreamWriter Apex class provides precise control over XML structure and is the Salesforce-recommended way to programmatically generate XML from data within a Remote Action step in an Integration Procedure.

Incorrect Options:

B. The XML checkbox in DataRaptor does not convert JSON to XML; it defines output data format for display or API serialization.

C. XMLStreamReader is used for parsing XML, not for generating it.

D. DataRaptor Transforms only manipulate JSON structure; they do not support converting JSON into XML format.

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

A Set Values Action in a Value field and a Remote Action in an Additional Output value field can execute a function like CONCAT or DATEDIFF by using the syntax {{function(parameters)}}. For example, {{CONCAT(‘Hello’, ‘World’)}} or {{DATEDIFF(‘2021-01-01’, ‘2021-01-31’)}}.

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.

 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 Integration Procedure Actions page, “To pass data from a Set Values action to a DataRaptor action, add the Set Values action name to the Additional Input field of the DataRaptor action.” 

From the OmniStudio OmniScript Documentation:

A Repeat Block (like BlkContacts) expects an array of objects.

Each item in the array must contain fields that exactly match the UI elements inside the block.

The parent JSON must include any top-level values used by individual input fields (like AccountName, AccountPhone).

Why the Other Options Are Incorrect:

B. Uses Contacts instead of BlkContacts, and is incomplete/malformed.

C. Repeats keys at the same level instead of using an array structure. This causes the data to overwrite and fail to display properly.

D. Uses incorrect keys like "Name" and "Phone" instead of expected "ContactName" and "ContactPhone", breaking field binding.

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 calculation procedure version that would execute on 2/15/2020 at 12:00 PM is the one that has the start date time and end date time that include that date and time, and also has the highest priority among the enabled versions. In this case, only version number 4 meets these criteria, as it has a start date time of 2/1/2020 12:00 AM, an end date time of 4/1/2020 12:00 AM, a priority of 1, and is enabled. The other versions either have a different start or end date time, a lower priority, or are not enabled.

 Using the LIMIT filter on the Extract definition allows the developer to specify the maximum number of results to return from the DataRaptor Extract. Defining a formula with the Filter function is used to filter the results based on a condition. Using a Custom Output Type when creating the DataRaptor is used to define the structure of the output data. Setting the Limit Property on the Action that calls the DataRaptor Extract has no effect on limiting the results.
