# Remote Config

Remote Config is a feature that allows you to replace values or properties managed in your application with parameter values defined in the Hackle Dashboard, enabling real-time control of application behavior and configuration.

Navigate to the Remote Config screen in the Hackle Dashboard to configure parameter information and set values based on user identification rules.

## remoteConfig

Calling the `remote_config()` method returns a `HackleRemoteConfig` instance that holds the Remote Config information for the user (configured parameters and rule information).\
`remote_config()` can receive User Identifier information to match user properties against Remote Config rule information.\
You can access the desired parameter and receive its value through the methods provided by `HackleRemoteConfig`.

```python
from hackle.model import HackleUser

# 원격 구성 정보 담은 인스턴스를 반환합니다.

user = HackleUser.builder() \
                 .device_id('ae2182e0') \
                 .build()

remote_config = hackle_client.remote_config(user=user)
```

## Remote Config Parameter Lookup

* The `HackleRemoteConfig` returned by the `remote_config()` method provides a `get()` method for looking up parameter values.
* Since parameter values configured on the Hackle Remote Config screen exist as key-value pairs, you can use the methods below according to the configured parameter type to receive the configured parameter value.

{% hint style="warning" %}
Remove Remote Config-related code after archiving.

Once a Remote Config parameter is archived, you can no longer access the parameter information. Therefore, after archiving a Remote Config parameter, be sure to clean up any related code.
{% endhint %}

```python
from hackle.model import HackleUser

# 원격 구성 정보 담은 인스턴스를 반환합니다.

user = HackleUser.builder() \
                 .device_id('ae2182e0') \
                 .build()

remote_config = hackle_client.remote_config(user=user)

# string 유형의 parameter값 예제
parameterValue = remote_config.get(key='parameter_key', default='default_value')
```

* The `parameterKey` of the `get()` method is the key configured in the Remote Config parameter settings.
* `defaultValue` is the value returned when the Remote Config value cannot be determined. The entered `defaultValue` may be returned in the following situations:
  * A. A value of a different type than the type set on the Remote Config screen is provided
  * B. An unconfigured parameter key is called
  * C. Hackle SDK initialization failure
  * D. Invalid identifier information is provided or does not exist
  * E. ETC
* To receive the configured information correctly, you must enter a value of the type that matches the parameter type you configured in `defaultValue`.
* The Remote Config parameter types provided by the SDK are string, number, and boolean. The JSON type configured on the Remote Config parameter screen can be received as a string. The default value for JSON type must be entered as a string type.
