Notes:

uuid: Serves as the {ns_id} parameter in other namespace API endpoints
api_key: Used as the password parameter when calling /system/login; the uuid is used as the name parameter for that endpoint
webhook_url: Must be a valid URL (query parameters supported), maximum length 255 characters. This endpoint will be called back via POST method with JSON payload when deposit or withdrawal operations complete.
- Deposit Callback (Fund In)
  
  When the system detects an incoming deposit to a wallet address, it will trigger a callback to the namespace's configured webhook_url. The recipient should then call the deposit query endpoint (/namespaces/{ns_id}/apps/{app_id}/groups/{group_id}/wallets/deposit) to retrieve detailed deposit information.
  
  Callback Method: POST
  Data Format: JSON
```
