These solutions are based on my experience and best effort. Actual results may vary depending on your setup. Codes may need some tweaking.

1. What are the most common external systems UiPath integrates with?

  • Web APIs (REST/SOAP)
  • ERPs like SAP, Oracle
  • CRMs like Salesforce, Dynamics 365
  • Databases (SQL Server, Oracle DB, PostgreSQL)
  • Email servers (Outlook, Gmail via IMAP/SMTP)
  • Cloud services (AWS, Azure, Google Drive)
  • Excel, CSV, PDF file systems
  • Message queues like Kafka, RabbitMQ

2. How does UiPath communicate with a REST API?

  • Using HTTP Request activity from UiPath.Web.Activities
  • Supports GET, POST, PUT, DELETE
  • Headers and authentication tokens can be passed
  • JSON body for POST/PUT operations
  • Response saved as JSON string, then deserialized if needed

3. Can you explain how OAuth2 is handled in UiPath for API calls?

  • Use HTTP Request with Authorization header
  • First call token endpoint to get access token
  • Store token in Orchestrator Asset or Orchestration Process
  • Add token in headers: Authorization: Bearer <access_token>
  • Refresh token logic should be handled with retry/reconnect strategy

4. Give an example where integrating with SAP went wrong in production. What was the root cause?

  • Scenario: SAP login failed mid-process
  • Cause: SAP session timeout due to large unattended bot queue
  • Fix: Added retry scope with re-login logic using SAP Login activity
  • Scheduled SAP health-check job to keep session alive

5. What’s the difference between integrating via API and UI automation?

  • API is faster, reliable, structured, less UI-dependent
  • UI automation depends on selectors, fragile with UI changes
  • Use API when available; fall back to UI when API not exposed
  • API supports error handling via status codes, UI needs try/catch

6. What’s your approach if an API you’re consuming returns inconsistent data?

  • Validate schema using Deserialize JSON with schema option
  • Add retry with condition check
  • Log malformed responses for analysis
  • Notify source system team or auto-send email alerts

7. How do you handle throttling limits in external API calls?

  • Read rate limits from API docs
  • Use Delay, Retry Scope, or Do While to pause calls
  • Store call counts in Orchestrator assets or queue item metadata
  • If 429 response, wait and retry with exponential backoff

8. In a project, you need to integrate with Salesforce. Which activities or connectors will you use?

  • Use UiPath Salesforce Connector from Integration Service
  • Authenticate via OAuth2
  • Use pre-built activities like Get Record, Create Record
  • Alternatively, call REST API using HTTP Request if custom object

9. How do you store and secure API credentials in UiPath?

  • Store API keys/tokens in Orchestrator as Credential Assets
  • Use Get Credential activity to fetch securely
  • Avoid hardcoding in workflows
  • Use Windows Credential Manager in local unattended bots

10. Describe a time you integrated with a cloud file system like Google Drive.

  • Used UiPath Google GSuite package
  • Connected via OAuth consent flow
  • Downloaded invoice files from shared folder
  • Triggered bot when new file appeared using Orchestrator Trigger

11. How do you monitor if the external system is down before running a bot?

  • Use API heartbeat/ping endpoints
  • Run a pre-check workflow with HTTP Request (GET)
  • Validate status codes (200 OK vs 5xx errors)
  • Abort process early with proper logs if target is unreachable

12. When integrating with a database, what’s your preferred setup?

  • Use Connect, Execute Query, and Disconnect activities
  • Use parameterized queries (avoid SQL injection)
  • Store connection string securely
  • If bulk data, use stored procedures

13. Can UiPath call external DLLs or scripts during integration?

  • Yes, via Invoke Code, Invoke VBA, or Call DLL activities
  • Use cases: encryption libs, custom file parsers, legacy VB scripts
  • Must deploy DLLs alongside the bot in unattended setup

14. What if two systems are not directly integrable? How do you bridge the gap?

  • Use intermediary queue (Orchestrator, Kafka, Azure Queue)
  • Store data in a shared location (SFTP/DB) both systems can access
  • Build a middleware microservice to expose APIs
  • Use custom connector or Power Automate bridge

15. In your integration projects, how do you log and trace external calls?

  • Always log:
    • Endpoint
    • Request/Response body (mask sensitive data)
    • Status code
  • Use Orchestrator Logs + Elastic Stack or Insights
  • Create custom logs table in DB for critical flows

16. Can UiPath integrate with legacy systems that don’t have APIs?

  • Yes, via:
    • Screen scraping + keyboard automation
    • Reading/writing flat files (CSV, XML, INI)
    • Email-based communication
    • RDP/Remote App automation if UI is accessible

17. Have you ever used UiPath Integration Service? What are its benefits?

  • Yes, it provides:
    • Native connectors to platforms (Salesforce, SAP, ServiceNow)
    • Easy drag-drop activities without complex auth logic
    • Centralized credential/token management
    • Faster setup for citizen developers

18. What precautions do you take while handling XML-based API responses?

  • Use Deserialize XML activity
  • Use XPath to extract values
  • Handle namespaces carefully
  • Validate schema (XSD) if available

19. How do you integrate UiPath with messaging systems like Kafka or RabbitMQ?

  • Use custom libraries or HTTP interface
  • Push/consume messages with specific keys
  • Ensure idempotency in processing
  • Use transaction status to control re-processing

20. What’s the role of Swagger/Postman when setting up API integrations?

  • Helps:
    • Understand endpoints
    • Generate sample requests
    • Validate headers, tokens
    • Export working calls to use in UiPath

21. What’s the most fragile part of integration via screen-based automation?

  • Selectors break with minor UI changes
  • App loading delays cause timeout errors
  • Keyboard inputs may not reach correct field
  • Multi-language UIs break consistency

22. Can UiPath send and receive data from Microsoft Power Automate?

  • Yes, via:
    • HTTP triggers in Power Automate
    • UiPath bot calling Power Automate Webhook
    • Power Automate calling UiPath via Orchestrator API
    • Both tools can exchange data via shared queues or files

23. What’s your error-handling strategy when integration fails mid-execution?

  • Use:
    • Try Catch block around API/DB calls
    • Log detailed error messages
    • Auto-retry with limit
    • Notify stakeholders via email/Teams
    • Store failed data in queue for manual reprocess

24. How do you handle time zone differences while integrating across regions?

  • Use UTC timestamps in all APIs
  • Convert local times using .ToUniversalTime() in .NET
  • Store user’s timezone in config
  • Apply time logic during transformation phase

25. What makes a UiPath integration project successful?

  • Clean and secure API handling
  • Proper logging and monitoring
  • Failover and retry design
  • Clear documentation of endpoints, tokens, and limits
  • Always use test environment before prod go-live
