This knowledge will help you construct and execute automation procedures more effectively.
1. Web Automation Tools
Microsoft Power Automate provides varied web automation capabilities that allow interactions with diverse web-based applications and browsers.
- UI Flows: UI flows record and play back user interface actions such as clicks and keyboard inputs for applications running on your desktop or in a browser.
- Selenium: Microsoft Power Automate can utilize Selenium, a popular open-source web testing framework. This tool allows automated interactions with HTML elements in a browser.
- WinAppDriver: Windows Application Driver (WinAppDriver) is a service that supports Selenium-like UI Test Automation on Windows Applications.
2. Desktop Automation Tools
For automating interaction with desktop applications, there are a couple of useful utility options.
- UI Flows: As mentioned earlier, UI Flows can be utilized to record and play back UI actions for desktop applications too.
- WinAutomation: Another tool for desktop automation is WinAutomation. It can interact with any desktop or web application, automating everything from simple tasks like clicking buttons and typing keystrokes, to complex operations using conditions, loops, and custom functions.
3. API Integration
Microsoft Power Automate also facilitates interaction with target applications through APIs. APIs allow different software applications to communicate and share data with each other.
- HTTP with Azure AD: Power Automate allows developers to make HTTP requests using Azure AD to connect with APIs.
- Custom Connectors: Developers can use and build custom connectors to make use of APIs through Power Automate.
Here is a comparison table of the above automation tools:
| Web Applications | Desktop Applications | API Interaction | |
|---|---|---|---|
| UI Flows | Yes | Yes | No |
| Selenium | Yes | No | No |
| WinAppDriver | Yes | Yes | No |
| WinAutomation | Yes | Yes | No |
| HTTP with Azure AD | No | No | Yes |
| Custom Connectors | Yes | No | Yes |
To sum up, understanding the various tools and methodologies of interaction with target applications and browsers is essential when preparing for the Microsoft Power Automate RPA developer exam. Beyond this, a solid grasp of these tools will definitely contribute towards effective RPA development. Understanding when to use what tool is key, and this comes with practice and hands-on experience.

Interview Questions
What is an Application Card in Power Automate?
An Application Card in Power Automate is an interface where all the interaction options with applications are listed. You can define unique application/window handlers or reuse a stored handler.
What are some methods to interact with target applications in Power Automate?
One can interact with target applications in Power Automate by using the Power Automate UI flows, Power Automate desktop, and interaction with web applications or browsers using Selenium WebDriver.
What is the role of Power Automate UI flows in interacting with target applications?
Power Automate UI Flows offer a way to record and playback actions performed on a screen, such as clicking and typing, and can be used to interact with target applications that do not have existing connectors in Power Automate.
What is Power Automate desktop?
Power Automate Desktop allows creating and running UI flows on a local machine. It’s ideal for automating applications accessed through a local machine or a virtual desktop environment.
What role does Selenium WebDriver play in interacting with web applications or browsers in Power Automate?
Selenium WebDriver is used to automate browser activities. It provides a programming interface for creating and executing test scripts to automate browser tasks which can be useful when dealing with complex workflows in Power Automate.
What are some types of UI interactions supported in Power Automate?
Power Automate supports various UI interactions including clicks, keystrokes, text inputs, and control selections.
How does Power Automate interact with target applications using a stored handler?
Stored handlers allow Power Automate to interact with an application at the window level, adding robustness to UI Flows by avoiding the need to locate windows based on unstable attributes.
Can Power Automate interact with applications via API calls?
Yes, if an application exposes APIs, Power Automate can interact with it via API calls using HTTP requests.
How does Power Automate interact with target applications that do not expose APIs?
For applications that don’t expose APIs, Power Automate can use UI flows to interact with the application by simulating user interface actions like button clicks and data input.
How can you error-proof UI interactions in Power Automate?
This can be achieved using error handling and retries in your flows. It is also recommended to add delays in UI interactions to wait for applications to fully load before starting the interaction.
What are variables and loops in Power Automate?
Variables are used to store, modify, and utilize information throughout a flow, while loops are used to perform specific actions repeatedly until certain conditions are met. Both are useful for interacting with target applications in Power Automate.
What is desktop recording in Power Automate?
Desktop recording is a feature in Power Automate Desktop that can be used to record and capture steps that interact with applications and web browsers. This recorded flow can then be played back.
What is web recording in Power Automate?
Web recording is a feature in Power Automate that records user interactions with a webpage and translates them into a sequence of automation steps.
What can be done to interact with an application that cannot be automated using Power Automate UI flows?
For applications that cannot be automated with UI flows, developers can use the Power Automate API or custom connectors to interact with the application programmatically.
How can Power Automate interact with browsers?
Power Automate interacts with browsers by using recording actions, executing JavaScript code, dealing with pop-ups and dialogs, and interacting with iframes and frames, etc.
