Manage Google Calendar events with Zalo Bot, OpenAI, and Gemini

Description

Quick Overview This workflow lets users manage Google Calendar by sending text or voice messages to a Zalo Official Account bot, transcribing voice notes with Google Gemini and using an OpenAI-powered agent to create, update, list, or delete events, then replying in Zalo with the result. How it works Receives an incoming text or voice message through a Zalo Bot trigger. Sends a typing indicator back to the Zalo chat and normalizes key message fields (chat ID, type, text, and voice URL). If the message is a voice note, sends the audio URL to Google Gemini to transcribe it into text. Sends the combined text/transcription to an OpenAI chat model agent that interprets the request in Vietnamese and decides whether to list, create, update, or delete a Google Calendar event. Uses Google Calendar tools to get events and then create, update, or delete the targeted event based on the agent’s extracted parameters. Sends the agent’s Markdown-formatted response back to the user in Zalo, and posts an error message to Zalo if the agent run fails. Setup Install the community node package n8n-nodes-zalo-bot-official and restart n8n if required. Connect your Zalo Bot API credentials and configure the Zalo webhook URL in your Zalo Official Account so incoming messages reach this workflow. Add a Google Calendar OAuth2 credential and set the target calendar account (currently configured as toannguyen96vn@gmail.com) for all calendar operations. Add a Google Gemini (PaLM) API credential for audio transcription and ensure voice messages include a reachable voice_url. Add an OpenAI API credential, select the chat model you want to use (currently gpt-5-mini), and adjust the system prompt/tone if needed.
