Introduction Copilot Studio allows users to enhance agent functionality by integrating existing Power Automate flows. These flows can be added directly to topics or utilized as tools within an agent. This post explains how to add Power Automate flows as tools and use them effectively within Copilot Studio. Adding Power Automate Flows to Topics Within a topic added to an agent, existing agent flows can be seamlessly integrated. This approach enhances the agent’s capabilities as well as introducing more probablistic behaviour to the agent.

Introduction Copilot Studio creates different types of flows based on whether they are created as a trigger (autonomous agent) or as part of action within Topics or elsewhere. These flows leverage Power Automate in the background. This post explores the distinctions between trigger flows and agent flows, their advantages, and how they integrate with Copilot Studio. Types of Flows in Copilot Studio Trigger Flows Trigger flows created within Copilot Studio Agents are assigned the Power Automate plan.

Introduction When building solutions in Copilot Studio, you may use Adaptive Cards to collect multi-choice input from users. The selected values from a multi-select field are stored as a table variable. However, if you want to pass these values to an Agent Flow (for example, to create a SharePoint list item), you need to convert the table variable into a single string. This post shows how to concatenate the selected values from a multi-choice Adaptive Card field into a semicolon-separated string using the concat function in a Set Variable value action within your topic.

When you create an Agent within Copilot Studio, a corresponding App registration is automatically generated. These app registrations are named after the Agent, suffixed with “(Microsoft Copilot Studio)”. You can view these app registrations in the Azure Portal under App registrations > All applications. Agent Certificates and Federated Identity Each app registration associated with a Copilot Studio Agent includes three certificates and two federated credentials as of January 2025. These components enable secure communication between agents and your data sources and services.
