Flowise

Connect CometAPI to Flowise with the ChatCometAPI node, set credentials, choose a model, and build an LLM Chain with prompt templates.

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.

Prerequisites

• A CometAPI account with an active API key — get yours here
• A FlowiseAI account — sign in here

1. Get your CometAPI API key

   Log in to the CometAPI console. Click Add API Key and copy your sk-xxxxx key.

   

   
2. Add the ChatCometAPI node

   1. In your FlowiseAI chatflow canvas, click Add New.

   

   2. Search for cometapi and select the ChatCometAPI node.

   

   3. Drag it onto the canvas.

   

   4. In the node’s Connect Credential dropdown, select Create New, enter your sk-xxxxx key, and save.

   

   Optionally set Model Name to the current model ID you want to use and Temperature (e.g. 0.7).

3. 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.
      

   

   

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

   

   
4. Connect nodes and save

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

   

Troubleshooting

• 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.
