FlowiseAI is a low-code platform for building LLM applications visually. Use the native ChatCometAPI node to connect CometAPI and build chatbots, Q&A systems, and agent workflows.

Get your CometAPI API key

Log in to the CometAPI console. Click Add API Key and copy your <COMETAPI_KEY> key.

Build the LLM Chain

  1. Add a Prompt Template node (search “Prompt”) and configure a template, e.g.: 
    Question: {question}
Answer: Let's think step by step.

  1. Add an LLM Chain node (search “Chain”). Connect:
    • Language Model input ← ChatCometAPI node
    • Prompt input ← Prompt Template node
  2. Give the chain a name, e.g. Universal Chat Assistant.

Connect nodes and save

Ensure the chain forms a complete flow: Input → Prompt Template → LLM Chain → Output. Click Save Chatflow.

  • Cannot find the “cometapi” node — ensure your FlowiseAI version supports this integration. Check for updates or relevant plugins.
  • Credential configuration failed — verify the API key is correct and has not expired. Copy it fresh from the CometAPI console.
  • Node connection error — confirm the connection lines point to the correct inputs (Language Model and Prompt). If the response quality is poor, adjust the Prompt Template or lower the Temperature value.
