You can create an AI agent in Langflow using Composio as a tool, an integration platform that gives developers access to hundreds of tools like GitHub, Salesforce, and Google. With Composio, you don't have to manage APIs for performing actions like creating, deleting, or updating a Google Calendar event; you just need to go through Composio and the work is done for you. To get started, create a new account with Composio and obtain an API key, then set up a Google calendar integration by following the steps in the platform's dashboard. You can then use this API key in Langflow to build a simple AI agent that interacts with your Google Calendar using the `GOOGLECALENDAR` app name. The agent uses the gpt-4o-mini model from OpenAI, but you can choose to use other models if preferred. With Composio and Langflow, you can easily connect multiple tools and perform actions without having to configure APIs yourself, and explore many integrations using Langflow's component-based visual app-building interface.
