-[Azure AI Agent Service](/azure/ai-services/agents/overview) allows you to create AI agents tailored to your needs through custom instructions and augmented by advanced tools like code interpreter, and custom functions. You can now connect your Azure AI Agent to an external API using an [OpenAPI 3.0](https://www.openapis.org/what-is-openapi) specified tool, allowing for scalable interoperability with various applications.

-Azure App Service is a fully managed platform for building, deploying, and scaling web apps and APIs. If your API is hosted on Azure App Service, you can connect your AI Agent to the API using the OpenAPI specification. The OpenAPI specification defines the API and how to interact with it. You can then use natural language to invoke the API through your AI Agent.

If your API is hosted on Azure App Service, you can connect your AI Agent to the API using the OpenAPI specification. The OpenAPI specification defines the API and how to interact with it. You can then use natural language to invoke the API through your AI Agent. This tool is powerful because it allows you to add AI agent capabilities to your existing apps with minimal code changes. Also, this agent has the ability to directly interact with your app. There's no need for significant code changes or implementation work other thank minor updates to interact with the agent using the available SDKs.

 1. **Chat Not Working**
    - Verify that the environment variables (`AzureAIAgent__ConnectionString` and `AzureAIAgent__AgentId`) are correctly set in the App Service environment variables.
    - Check that the AI Agent is properly created and configured with the correct OpenAPI tool.

    - Ensure the App Service URL is updated in the `swagger.json` provided to the OpenAPI Specified Tool.
 1. **Permission Issues**
-   - If you encounter authentication errors, ensure that your App Service's managed identity has proper permissions to access the Azure AI Agent Service. The managed identity needs at least the `Microsoft.MachineLearningServices/workspaces/agents/action` permission to interact with the Agent. The provided "Azure AI Developer role" has this permission and should be sufficient. If you decide to change this role, be sure it has the necessary permission.
