API Automation

An automation developer is using the HTTP Request activity in UiPath Studio to call a REST API that requires a bearer token. The token is stored in Orchestrator as an asset named "APIToken". The developer needs to include the token in the request header. Which approach should be used?

A developer is building a UiPath automation that consumes a REST API. The API returns a JSON response with a 'status' field and a 'data' array. The developer needs to handle both successful responses and error responses gracefully. Which two actions should the developer take to ensure robust error handling? (Choose two.)

A developer is using the HTTP Request activity to call a REST API that returns a 401 Unauthorized response. The API documentation states that the access token must be included in the 'Authorization' header as 'Bearer <token>'. The developer has already obtained a valid token and stored it in a string variable named 'accessToken'. Which configuration should the developer apply to the HTTP Request activity to ensure the token is sent correctly?

A developer is building an API workflow that must call a protected endpoint. The API requires a Bearer token that expires every 60 minutes. The developer uses the HTTP Request activity in a UiPath Studio project and wants to avoid hardcoding credentials. They have already configured an Orchestrator asset of type Credential named 'ApiUser' that stores the client ID and secret. Which approach should the developer use to obtain and attach the token to each request?

A developer is configuring OAuth 2.0 authorization code flow within UiPath Orchestrator and API activities to connect securely to a corporate CRM system. The security team mandates that client secrets must never be exposed or stored in plain text configuration files. Which authentication mechanism or credential management pattern should the developer implement?

A developer is using the UiPath HTTP Request activity to call a REST API that returns a JSON response. The developer needs to extract a specific value from the response body. Which activity should be used to convert the JSON response string into a manipulable object?

A developer is using the UiPath HTTP Request activity to send a POST request to an API that expects a JSON payload. The developer has a Dictionary(Of String, Object) variable named payloadDict containing the data to send. Which approach correctly serializes the dictionary and configures the request?

A developer is automating a process that calls a REST API which returns a large JSON response containing a 'results' array with 10,000 objects. The developer uses the Deserialize JSON activity and then a For Each loop to process each object. The workflow is running slowly and consuming high memory. Which approach should the developer take to improve performance while still processing all objects?

A developer has built a UiPath API workflow that calls a vendor's REST endpoint returning a JSON object with a nested 'items' array. The response is large, and the developer needs to extract only the 'id' field from each element in 'items' to feed a downstream process. The HTTP Request activity's output is stored in a variable of type String. Which approach should the developer use to reliably extract the required values?

An automation developer is troubleshooting an API workflow where a POST request to an external service intermittently returns a 429 Too Many Requests status code. Which TWO strategies should the developer implement in UiPath Studio to handle this rate-limiting scenario gracefully? (Choose two)

A developer is using the UiPath HTTP Request activity to call a REST API that returns a JSON array of customer records. The API paginates results and includes a 'nextPageToken' field in the response body when more data is available. The developer needs to retrieve all pages and aggregate the results into a single DataTable. Which approach should the developer use in the UiPath workflow?

A developer needs to call a REST API that requires an API key to be passed as a query parameter named 'api_key'. The developer is using the UiPath HTTP Request activity. Which property should the developer use to add this parameter?

An automation developer is building an integration with a third-party REST API that returns a JSON payload containing over 50,000 transaction records per request. The process frequently throws an OutOfMemoryException inside UiPath Studio when attempting to parse the entire response string using standard string manipulation. Which approach should the developer use to handle this large response efficiently?

A developer is using the UiPath HTTP Request activity to call an API that requires a bearer token. The token is obtained from an authentication endpoint and stored in a String variable named authToken. The developer must ensure that the token is sent in the Authorization header for every subsequent request. Which configuration in the HTTP Request activity correctly achieves this?

A developer uses the HTTP Request activity in a UiPath Studio project to call a REST API that returns a deeply nested JSON response. The developer needs to extract a specific value located at a path of several levels, and the response structure may vary slightly between calls. The developer wants to avoid deserializing the entire payload into custom classes. Which approach is most appropriate?
