20+ practice questions focused on API-Based Automation — one of the most tested topics on the UiPath Automation Developer Associate exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start API-Based Automation PracticeWhich activity should be used to securely pass a sensitive password to an API as part of a login request without exposing it in the logs?
Explanation: The 'SecureString' type is designed to store sensitive information in an encrypted format in memory. When a SecureString variable is used, UiPath handles it securely, and it will not be displayed in plain text in execution logs or the Locals panel, protecting it from unauthorized exposure. This is a standard security practice for handling credentials in UiPath.
An automation developer is designing a workflow to retrieve invoice data from a REST API that requires OAuth 2.0 authentication. Which approach is the most efficient and secure way to handle this in UiPath Studio?
Explanation: The 'HTTP Request' activity supports 'None', 'Basic', and 'APIKey' authentication types. OAuth 2.0 flows in UiPath are typically handled by using the 'UiPath.WebAPI.Activities' package's 'OAuth2Token' activity or by manually performing the token exchange via an HTTP Request activity and storing the result in a secure asset or variable. Option C describes a feature that does not exist in the standard activity properties.
A UiPath developer is building a workflow that calls a REST API which returns a JSON array of customer records. The developer needs to iterate over each customer record and extract the 'customerId' field. The HTTP Request activity has already been configured and the response content is stored in a variable named responseContent. Which two activities or steps are necessary to correctly parse and iterate through the JSON array? (Choose two.)
Explanation: To process a JSON array response, the developer must first deserialize the JSON string into a JArray using the Deserialize JSON activity. Then, a For Each activity with TypeArgument JObject can iterate over each element, allowing access to fields like 'customerId'. This combination leverages UiPath's built-in JSON handling capabilities and is the standard method for such scenarios.
A UiPath developer is automating a process that interacts with a REST API requiring OAuth 2.0 authentication. The developer needs to obtain an access token using the client credentials grant type, then use that token in subsequent API calls. The HTTP Request activity is used for both token retrieval and API calls. Which configuration correctly handles the token retrieval and usage?
Explanation: For OAuth 2.0 client credentials grant, the token request must be a POST to the token endpoint with the required parameters. The access token is then included in subsequent requests as a Bearer token in the Authorization header. This ensures secure and standard-compliant authentication with the API.
A UiPath developer is using the HTTP Request activity to call a REST API that requires a bearer token for authentication. The token is stored in a secure asset in Orchestrator. The developer wants to ensure the token is not exposed in logs. Which configuration should be used?
Explanation: The HTTP Request activity requires manual configuration of the Authorization header for bearer tokens. The token should be retrieved from a secure asset and added to the Headers property. To prevent exposure, developers must avoid logging the token and can control logging levels. UiPath does not automatically mask headers, so explicit care is needed.

Start with 10 questions to gauge your current understanding of API-Based Automation. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
API-Based Automation questions on the UiPath-ADAv1 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
