Has anyone built an AI agent that utilizes tool calling with n8n? For example: An organization has different branches, and each branch has its own APIs for specific tasks (e.g., calculations, cashback). You use the n8n HTTP Request node and define rules so the AI knows exactly which function to call and also when to use the API response from one request to make another HTTP request and give answers to "questions". I built something like this with Python, LangChain, and Flask, but I'd love to see how people are doing it natively in n8n!

did Ryan make a video about it or not, will you make one ? @Ryan Nolan

A few months ago, I worked with a transportation and delivery company that was struggling with delayed dispatch, manual tracking, and constant customer complaints. Their team spent hours coordinating drivers, confirming deliveries, and updating clients manually. It was draining their time and limiting their growth. I implemented a streamlined automation system that handled dispatch scheduling, real time tracking updates, customer notifications, and performance reporting. Within weeks, delivery times improved, errors dropped significantly, and customer satisfaction increased. The owner finally had clear visibility into operations and could focus on scaling instead of micromanaging daily tasks. Automation did not just make their process faster. It made the entire operation smarter, more reliable, and more profitable.

Need help integrating my n8n RAG agent with GoHighLevel live chat—want user messages to trigger my agent and send AI replies back. Anyone tried this setup?

Hey everyone, I’ve built a basic workflow to automate posting to X (Twitter). Although the API connection is successful, the posts are failing. I’ve attached a screenshot of the error—any ideas on how to fix this?
