Exam OmniStudio-Developer Topic 4 Question 51 Discussion

Integration Procedure is the correct tool because the requirement goes beyond a simple Salesforce record extraction. Complex filtering, sorting, aggregation, orchestration, and preparation should be handled server- side before the OmniScript displays the result. A Data Mapper Extract is appropriate for retrieving Salesforce data, but it is not the best orchestration layer when multiple operations and preparation logic are required. An HTTP Action only calls an external endpoint; it does not by itself manage the full data-preparation workflow.
A Set Values Action is useful for assigning values in the OmniScript data JSON, not for complex server-side data shaping. Salesforce describes Integration Procedures as server-side processes used to automate data operations between Salesforce and external systems, which matches this requirement.
