n8n is a workflow automation tool. Connect it to CometAPI by configuring OpenAI-compatible credentials — all CometAPI models work out of the box.

​
Prerequisites

  • An n8n account (cloud or self-hosted)
  • A CometAPI account with an active API key
For local/self-hosted n8n with the CometAPI community node, see the n8n Local Deployment guide.

​
Setup

1

Get your CometAPI API key

Log in to the CometAPI dashboard. Click Add API Key and copy your key and base URL (https://api.cometapi.com).

Create an OpenAI credential

In n8n, navigate to your project → Credentials → Create Credential → OpenAI API. Paste your CometAPI key into API Key, enter https://api.cometapi.com/v1 in the Base URL field, and click Save.

Test the connection

Create a workflow with an OpenAI node using the saved credential and execute it. A successful response confirms the setup is working.
