An API Key is your credential for accessing Comfy Platform services, including:

• Cloud API — call Comfy Cloud endpoints programmatically
• Partner Node API Integration — use paid Partner Nodes in your local workflows
• Agent Tools / MCP — connect to Comfy through MCP
• Login to ComfyUI locally — authenticate with an API Key instead of email

Creating an API Key

Managing your API Keys

You can view and manage all your API Keys on platform.comfy.org after logging in.

• View existing keys: See the name and creation date of each key
• Delete a key: If a key is compromised or no longer needed, delete it immediately
• Create additional keys: You can have multiple API Keys for different applications

API Keys are only shown once upon creation. Save it immediately in a secure location. If you lose a key, delete it and create a new one.

Using your API Key

Once you have an API Key, you can:

1. Log in to ComfyUI locally — go to Settings → User and select "Comfy API Key" login
2. Call Partner Node APIs — include the key in extra_data.api_key_comfy_org when sending workflows
3. Use Cloud API — include the key in request headers for Cloud API endpoints

For security, never share your API Key or commit it to version control.
