import GetApiKey from '/snippets/get-api-key.mdx'

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

- [Cloud API](/development/cloud/overview) — call Comfy Cloud endpoints programmatically
- [Partner Node API Integration](/development/comfyui-server/api-key-integration) — use paid Partner Nodes in your local workflows
- [Agent Tools / MCP](/agent-tools) — connect to Comfy through MCP
- [Login to ComfyUI locally](/interface/user#logging-in-with-an-api-key) — authenticate with an API Key instead of email

## Creating an API Key

<GetApiKey />

## Managing your API Keys

You can view and manage all your API Keys on [platform.comfy.org](https://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

<Warning>
  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.
</Warning>

## 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.
