Signatures from Power Apps Using Power Automate

Key insights

• Power Automate and Power Apps work together to fetch images from SharePoint and capture dynamic signatures. These features allow users to display real-time images and collect handwritten or digital signatures directly within apps.


• The 2025 updates introduced the new Power Apps (V2) trigger, which makes it easier to send different types of data—like images or signature files—from Power Apps into Power Automate flows for processing.


• SharePoint integration with Power Apps has improved, supporting better handling of media files. This lets users build apps that securely access and show images stored in SharePoint libraries or lists.


• This approach supports low-code automation. Teams can set up image fetching and signature capturing with minimal coding, speeding up app development while keeping workflows flexible.


• The system offers dynamic and real-time data processing. Images pulled from SharePoint and signatures collected in Power Apps are immediately processed by Power Automate, allowing instant storage or embedding into documents.


• To implement this solution: store images in SharePoint, create a Power App with image and pen input controls, build a flow using the V2 trigger, connect the app to the flow for sending data, then customize permissions and publish your app for use.

Introduction to Enhanced Automation with Power Automate, Power Apps, and SharePoint

In March 2025, Microsoft showcased the expanding capabilities of its Power Platform during a community call. The focus was on integrating Power Automate, Power Apps, and SharePoint to fetch images and capture dynamic signatures within business applications. This YouTube video demonstration provided valuable insights into how organizations can automate document creation and enhance user interaction through these technologies.

The session highlighted not only the technical steps but also the real-world impact of such integrations. As businesses increasingly look for low-code solutions to streamline processes, understanding the synergy between these tools becomes crucial. The demonstration was led by Nilüfer Doğan, who emphasized practical approaches and new features now available in 2025.

Technology Overview: Connecting Images and Signatures

At the core of the demonstration was the ability to fetch images stored in SharePoint and use them dynamically in Power Apps. By leveraging Power Automate connectors, users can retrieve image URLs or even base64-encoded images directly from SharePoint libraries or lists. This seamless integration allows for real-time display of images within apps, enhancing both functionality and user experience.

Additionally, the session explored capturing handwritten or digital signatures using pen input controls in Power Apps. These signatures can be processed and stored via Power Automate, either in SharePoint or embedded within documents and emails. This approach simplifies the collection and management of approval or proof-of-delivery signatures, making workflows more efficient.

Key Updates and Integration Improvements in 2025

The 2025 Release Wave 1 for Power Automate introduced several enhancements aimed at making automation more intelligent and enterprise-ready. Notably, the new Power Apps (V2) trigger allows for the seamless transfer of complex data structures—including images and signature files—from Power Apps to Power Automate. This advancement makes it easier to build robust, flexible flows that handle a variety of data types.

Moreover, Power Apps now offers improved integration with SharePoint, supporting richer data connections and better handling of media files. These upgrades ensure that images and other content are accessed securely and displayed responsively, which is vital for collaborative business environments. The result is a smoother, more reliable experience for users who rely on SharePoint as a central repository for documents and media.

Advantages and Tradeoffs of the Automated Approach

One of the standout benefits of this integration is its low-code nature. By using Power Automate flows triggered from Power Apps, organizations can implement image fetching and signature capture with minimal development effort. This not only speeds up deployment but also reduces the need for specialized technical skills.

However, balancing flexibility and security presents challenges. While dynamic data retrieval and real-time signature processing offer significant advantages, organizations must ensure that permissions are managed correctly and sensitive data is protected. Additionally, the increased complexity of flows—especially when dealing with multiple images or signatures—requires careful planning and ongoing monitoring, a task made easier with Power Automate’s new process maps and orchestration tools.

Implementing Image Fetch and Signature Capture: A Practical Guide

To get started, images and documents should be stored in accessible SharePoint libraries or lists. Power Apps then provides the interface, using image controls to display pictures and pen controls to capture signatures. Through the Power Apps (V2) trigger, these inputs are sent to Power Automate, where they can be processed—such as converting signatures to files—and saved back to SharePoint or other storage locations.

The final step involves integrating the automated flow with the Power App, ensuring that parameters like image URLs and signature content are passed correctly and responses are handled efficiently. While this process is straightforward for single images or signatures, handling collections or multiple data points may require additional customization but allows for greater scalability and flexibility.

Conclusion: A Step Forward in Digital Automation

The demonstration by Microsoft underscores the continuous evolution of the Power Platform, particularly in automating document creation and managing digital assets. By combining the strengths of Power Automate, Power Apps, and SharePoint, organizations can create dynamic, scalable solutions to meet modern business needs. As these tools become more integrated and powerful, the tradeoff between ease of use and advanced functionality becomes less pronounced, opening new possibilities for digital transformation.
