UiPath-ADAv1 API-Based Automation Practice Question
Exhibit
Response Body: {"status": "success", "data": {"id": 101, "user": "admin"}}Refer to the exhibit. After invoking an API, you receive the JSON structure shown. Which activity and property configuration is required to extract the 'id' value into a variable?
⚠ Common exam trap
Candidates frequently try to access JSON values directly from the raw string output of the HTTP Request without using the 'Deserialize JSON' activity first to create a usable object.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use 'Deserialize JSON' then access via 'jsonObject("data")("id").ToString'.
To extract nested values from a JSON response, one must first convert the string response into a JObject using the Deserialize JSON activity. Once in object form, the JObject can be navigated using standard dot notation or string indexing. This is a fundamental skill for API-based automation because it allows robots to programmatically access specific data fields needed for subsequent logic or UI-based interactions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use 'Get Text' activity with 'data.id' as the selector.
Why it's wrong here
Get Text is a UI Automation activity used for interacting with browser elements or desktop windows. It cannot parse or manipulate raw JSON response strings returned from web services. It requires a valid UI selector to function, which is not applicable when dealing with raw data structures like JSON objects.
- ✓
Use 'Deserialize JSON' then access via 'jsonObject("data")("id").ToString'.
Why this is correct
The Deserialize JSON activity converts the raw string into a JObject. By accessing the root object, you can traverse the hierarchy using the keys 'data' then 'id'. Converting the final result to a string allows the value to be stored in a standard UiPath string variable for later processing.
- ✗
Use 'Assign' activity to read the response string directly using string splitting.
Why it's wrong here
String splitting is highly fragile and prone to errors if the JSON format changes slightly, such as whitespace variations or key ordering. It does not parse the underlying data structure correctly. Using formal JSON parsing activities ensures the automation remains resilient to minor formatting changes in the API response.
- ✗
Use 'Deserialize JSON Array' to extract the 'id' field.
Why it's wrong here
Deserialize JSON Array is specifically for parsing JSON structures that start with square brackets, indicating a list of items. Since the exhibit shows a JSON object starting with curly braces, this activity will throw an invalid cast exception during execution because it expects an array type instead of an object.
