Introduction After encountering issues with creating a To-Do task action in my previous attempt Building a Copilot Agent with Teams Toolkit and Microsoft Graph Plugin to list my ToDo Tasks, I explored various methods to generate an OpenAPI specification for M365 Copilot Declarative Agents using the Ms Graph OpenAPI spec. This post outlines the different approaches I tried, the challenges I faced, and the lessons learned. Methods for Generating OpenAPI Specs 1.

Introduction In this post, I’ll walk you through how to call Azure AI Search APIs from a M365 Copilot declarative agent without writing any code by using Teams Toolkit. Leveraging OpenAPI specifications, Teams Toolkit enables seamless integration with Azure AI Search, streamlining the development process for Copilot extensibility. Waldek Mastykarz wrote an insightful post on when Azure AI Search can be used, highlighting its ability to provide a more controlled approach to indexing and relevance without the complexity of building a custom engine agent.

Introduction In this post, I’ll walk you through how to call Azure OpenAI APIs from a Copilot declarative agent—without writing any code—by using Teams Toolkit. Leveraging OpenAPI specifications, Teams Toolkit enables seamless integration with Azure OpenAI, streamlining the development process for Copilot extensibility. Step 1: Create and Import an OpenAPI Specification Microsoft provides a pre-built OpenAPI specification for Azure OpenAI, but it’s often broader than needed. To simplify, I generated a targeted OpenAPI spec with Copilot by using the endpoint URL and a sample request body as a prompt.
