# Authentication
> Authenticate with the ComfyUI Cloud Developer API
## API Keys
All Developer API requests require authentication via API key. These are the same API keys used for [Partner Nodes](/tutorials/partner-nodes/overview) and other Comfy platform features.
### Getting Your API Key
API keys are managed at [platform.comfy.org](https://platform.comfy.org/login):
Go to [platform.comfy.org/login](https://platform.comfy.org/login) and sign in with your Comfy account (Email, Google, or GitHub).
Click **+ New** in the API Keys section.
Enter a descriptive name (e.g., "Production Backend", "Local Dev") and click **Generate**.
Copy and save your API key immediately.
The API key is only shown once at creation. Store it securely - you cannot view it again later.
### Managing API Keys
You can view and delete your API keys at [platform.comfy.org](https://platform.comfy.org/login):
Delete any unused keys or keys that may have been compromised.
## Using Your API Key
Include the API key in the `Authorization` header:
```bash theme={null}
curl https://cloud.comfy.org/developer/api/v1/account \
-H "Authorization: Bearer comfyui-abc123..."
```
With the Python SDK:
```python theme={null}
from comfy_cloud import ComfyCloudClient
client = ComfyCloudClient(api_key="comfyui-abc123...")
```
### Environment Variables
We recommend storing your API key in environment variables:
```bash theme={null}
export COMFY_API_KEY="comfyui-abc123..."
```
```python theme={null}
import os
from comfy_cloud import ComfyCloudClient
client = ComfyCloudClient(api_key=os.environ["COMFY_API_KEY"])
```
Never commit API keys to version control. Use environment variables or a secrets manager.
## Environments
| Environment | Base URL |
| ----------- | ------------------------------------------------- |
| Production | `https://cloud.comfy.org/developer/api/v1` |
| Staging | `https://stagingcloud.comfy.org/developer/api/v1` |
```python theme={null}
# Using staging
client = ComfyCloudClient(
api_key="comfyui-...",
base_url="https://stagingcloud.comfy.org/developer/api/v1",
)
```
## Rate Limits
The API has rate limits to ensure fair usage:
| Limit | Value |
| ------------------- | ------------- |
| Requests per minute | 600 |
| Concurrent jobs | Based on plan |
| Max upload size | 100 MB |
When rate limited, you'll receive a `429 Too Many Requests` response. Implement exponential backoff in your retry logic.
## Error Responses
Authentication errors return `401 Unauthorized`:
```json theme={null}
{
"error": {
"type": "unauthorized",
"message": "Invalid or expired API key"
}
}
```
Common causes:
* Missing `Authorization` header
* Malformed header (should be `Bearer `)
* Revoked or deleted API key
* Using wrong environment's key
