• No-code integration: Non-developers can create API workflows by configuring settings in Power Automate Desktop, automating tasks like data retrieval or updates across local apps and cloud services.
  
• The tool handles and parses JSON responses, letting users extract information for further use—such as writing results into Excel spreadsheets or triggering other automated actions within their workflow.
  
• Recent updates (2025) include step-by-step tutorials that guide users from basic GET requests to advanced scenarios involving dynamic endpoints, complex JSON handling, and even integrating AI for smarter automation outputs.
  
• This technology helps bridge desktop automation with modern APIs, empowering both beginners and advanced users to automate business processes efficiently—without needing custom code.

Introduction to API Calls in Power Automate Desktop

Power Automate Desktop (PAD) has made significant strides in simplifying the process of connecting desktop automations with web services. In a recent tutorial video by Anders Jensen [MVP], viewers are introduced to the core concepts of making API calls using the Invoke Web Service action. This beginner-friendly guide focuses on executing a simple GET request to a public REST API, all without the need for coding. The tutorial is designed to help users understand how to configure and validate API calls using Power Automate Desktop’s built-in tools.

As digital automation becomes increasingly important, such features empower non-developers and business professionals to automate complex workflows and integrate data from various sources. The video provides a practical entry point for those new to APIs, making it easier to bridge the gap between local applications and cloud-based services.

Understanding the Invoke Web Service Action

At the heart of this technology is the Invoke Web Service action, which allows users to send HTTP requests—including GET, POST, PUT, and DELETE—to RESTful APIs. By configuring parameters like endpoints, headers, and request bodies, users can interact with almost any system that exposes a web API. The ability to process the response within PAD enables seamless integration and data manipulation.

This approach eliminates the need for traditional programming, letting users simply drag the action into their workflow, set the necessary parameters, and immediately interact with external data sources. As a result, organizations can achieve faster automation results and reduce dependency on IT development resources.

Key Benefits and Tradeoffs

One of the standout benefits highlighted in the video is the no-code integration offered by Power Automate Desktop. Users with little or no coding experience can configure powerful API workflows, from basic data retrieval with GET requests to more advanced operations requiring authentication and dynamic parameters. Additionally, PAD’s ability to parse and manipulate JSON responses makes it suitable for interacting with modern APIs, where JSON is the standard data format.

However, there are tradeoffs to consider. While PAD simplifies the process, it may not offer the same flexibility as traditional code-based solutions for highly complex integrations. Furthermore, handling advanced security requirements or managing large volumes of data may still require some technical expertise. Despite these challenges, the convenience and accessibility of PAD’s API capabilities make it an attractive option for many business scenarios.

New Features and Evolving Capabilities

According to the tutorial and recent updates, Power Automate Desktop now offers step-by-step resources, helping users progress from basic GET requests to building comprehensive API workflows. These guides include practical examples, demonstrating how to configure HTTP methods, endpoints, headers, and request bodies within PAD. Moreover, new features allow users to work with dynamic endpoints and complex JSON responses, further expanding the tool’s versatility.

A particularly noteworthy development is the integration of AI, such as OpenAI, directly into PAD workflows. This enhancement allows users to automate decision-making based on API data, streamlining processes that once required manual intervention. Additionally, the ability to push data from on-premises apps to cloud services via API calls addresses the needs of organizations with strict data access policies.

Challenges and Considerations

While the Invoke Web Service action makes API integration accessible, users may encounter challenges when dealing with complex authentication schemes or APIs requiring advanced input formatting. Ensuring data security and handling potential errors in API responses are also important considerations. For some scenarios, users might need to familiarize themselves with basic concepts like HTTP headers, tokens, or JSON structures to fully leverage PAD’s capabilities.

Balancing ease of use with the need for advanced functionality remains a central challenge. Power Automate Desktop addresses this by offering extensive documentation and practical examples, but users seeking highly customized integrations may still need to supplement PAD’s features with additional technical knowledge.

Conclusion

In summary, the video by Anders Jensen [MVP] illustrates how Power Automate Desktop’s Invoke Web Service action democratizes API integration. Through intuitive, no-code workflows, users can connect desktop automations with web services, manipulate API data, and even enhance outputs with AI. This approach accelerates digital transformation, enabling organizations to automate data exchange and streamline business processes with minimal technical barriers.

As Power Automate Desktop continues to evolve, the balance between usability and advanced functionality will shape how businesses adopt and expand their automation strategies. The ongoing development of resources and features ensures that both beginners and advanced users can find value in this powerful tool.
