        \"SGP_API_TOKEN\": \"your_token\"
      }
    }
  }
}

Authentication Methods

1. Basic Authentication

Uses username and password for SGP admin access:

SGP_USERNAME=admin_user
SGP_PASSWORD=admin_password

2. Token Authentication

Uses API token for enhanced security:

SGP_API_TOKEN=your_api_token
SGP_APP_NAME=your_app_name

3. CPF/CNPJ Authentication

For customer portal access (passed in function calls):

{
  \"cpfcnpj\": \"12345678900\",
  \"senha\": \"customer_password\"
}

Rate Limits

• Basic Auth: 100 requests/minute
• Token Auth: 300 requests/minute
• CPF/CNPJ Auth: 50 requests/minute

Caching

The server implements intelligent caching:

• Default TTL: 5 minutes
• Max Keys: 1000
• Cache Keys: Automatically generated based on endpoint and parameters

Error Handling

• Automatic retry with exponential backoff
• Comprehensive error logging
• Graceful degradation for rate limits
• Clear error messages in API responses
