Three of the 80 questions in this pack

Question 1

A developer is creating an OmniScript that provisions trial orgs to their customers. The following text block in the OmniScript uses a merge code to display the ID for the new trial org:

Welcome to Salesforce!

Your ID is %Details:Customer|0:ID% During testing, the developer notices that the ID does not display. The data JSON is structured as shown below.

How should the developer correct the merge code in order for the ID to display?

Exhibit for question 1

  1. To %Details:Customer|n:ID%
  2. To $Details:Customer|0:ID$
  3. To %Details:Customer|1:ID%
  4. To %%Details:Customer|0:ID%%
Show answer and explanation

Correct answer: C. To %Details:Customer|1:ID%

In OmniScript merge codes, the syntax %Details:Customer|index:ID% uses the index parameter to specify which element in an array to access. Since the JSON shows Customer as an array with a single object at index 0, the original merge code %Details:Customer|0:ID% attempts to access the first element. However, the developer needs to use index 1 to correctly reference the data in this context, as OmniScript array indexing for merge codes uses 1-based indexing rather than 0-based indexing. Therefore, %Details:Customer|1:ID% is the correct merge code to display the ID value.

Why the other options are wrong

  • A. Using 'n' as the index parameter is not valid OmniScript merge code syntax; numeric indices are required.
  • B. Dollar signs ($) are not the correct delimiters for OmniScript merge codes; percent signs (%) are required.
  • D. Double percent signs (%%) are not valid OmniScript merge code syntax; single percent signs (%) are the correct delimiters.

Question 2

A developer is building an OmniScript and needs to retrieve data from many fields in a Salesforce record.

Which OmniScript element does this?

  1. Lookup
  2. HTTP Action
  3. Select
  4. DataRaptor Extract Action
Show answer and explanation

Correct answer: D. DataRaptor Extract Action

DataRaptor Extract Action is specifically designed to retrieve data from multiple fields in a Salesforce record. It queries the database and extracts field values efficiently, making it the correct choice for retrieving many fields from a single record. Lookup is for finding specific records, HTTP Action is for external integrations, and Select is a UI element for user input.

Why the other options are wrong

  • A. Lookup is used to find and display a single record, not to retrieve multiple fields from an already-known record.
  • B. HTTP Action is for calling external APIs, not for retrieving data from Salesforce records.
  • C. Select is a UI component for user selection, not a data retrieval mechanism.

Question 3

A developer creates an OmniScript to display FirstName, LastName, and BirthDate of a contact using a Type Ahead Block. The DataRaptor used in the Type Ahead has been tested and fetches the correct data.

When previewing the OmniScript, the developer enters a name in the Type Ahead and makes a selection of a contact from the list. However, the text fields FirstName, LastName. and BirthDate are not getting populated with the data.

Refer to the exhibit below.

What is the reason that the fields fail to display the fetched data?

Exhibit for question 3

  1. Use Data JSON is not selected in the properties of the Type Ahead Block.
  2. The Typeahead Key is not in the correct format.
  3. Lookup Mode is not selected in the properties of the Type Ahead Block.
  4. FirstName, LastName, and BirthDate are not placed inside the Type Ahead Block.
Show answer and explanation

Correct answer: D. FirstName, LastName, and BirthDate are not placed inside the Type Ahead Block.

inside the Type Ahead Block. In OmniScript, when using a Type Ahead Block to fetch and populate data into other fields, those fields must be placed inside the Type Ahead Block itself for the data binding to work correctly. The exhibit shows FirstName, LastName, and BirthDate listed separately in the Script Configuration under Step1, outside of the TAContact Type Ahead Block. When fields are not nested within the Type Ahead Block, they cannot receive the data that the Type Ahead action returns upon selection. The Type Ahead must contain the target fields to establish the proper data flow from the DataRaptor response to those fields.

Why the other options are wrong

  • A. Use Data JSON is used for configuring the input data source for the Type Ahead, not for populating output fields after selection.
  • B. The Typeahead Key field appears empty in the exhibit but incomplete configuration would typically result in no suggestions appearing, not a failure to populate already- selected data.
  • C. Lookup Mode is not a standard Type Ahead Block property; this configuration option does not control data population to external fields.

What makes the OmniStudio Developer hard

OmniStudio Developer is the build exam for the Vlocity toolset that now underpins Salesforce Industries, and it is far more configuration-heavy than Platform Developer: the questions are about which OmniStudio component to use, how the JSON data flows between them, and what breaks when it is configured wrong, rather than Apex. It is 60 questions in 105 minutes with a pass mark of 72%, and Salesforce recommends at least six months of hands-on OmniStudio work before sitting it.

OmniScripts carry the largest share of the exam: the OmniScript structure, elements and steps, conditional views and branching, the JSON data model at each step, the Standard versus LWC runtime, reusable OmniScripts, and calling DataRaptors, Integration Procedures and Calculation Procedures from inside them. FlexCards covers card design, states and conditions, data sources, actions, flyouts, child cards and the Interaction Console. Data tools covers the four DataRaptor types (Extract, Turbo Extract, Load and Transform), formulas, relationship queries and the JSON they produce. Integration Procedures covers orchestrating multiple server-side actions, HTTP actions to external systems, caching, chaining and when an Integration Procedure should sit between the UI and the data. Web page integration and OmniStudio tools cover embedding components in Lightning pages, Experience Cloud and external sites, the debug and preview tools, and packaging and deploying components as metadata.

Expect questions that give a broken interaction and ask which element or mapping is wrong.
