Login API Settings

Once the registered service information setting is completed, you can set up the login API.

Secret Key

When a service is registered, the Secret Key will be issued for each platform.

Use the Web key for JavaScript SDK, the Native App key for iOS and Android SDK, and the Server key for HTTP requests or server implementations. If you use an app key that does not fit the platform when calling the ifree API, you will receive an error response.

The Secret Key can be reissued in an emergency, and if you want to use the reissued key, you can apply the key applied to the service application or website with the changed value. When the service is applied, delete the unused keys so that only the keys that are always in use can be checked.

Personal information provision

You can use the ifree account information of the user that is logged in to ifree for the operation of the service. The service application can request item-by-item consent for user information to be provided to the service upon user login. User information is provided through ifree API for items agreed by the user.

You can receive the required information ➊[select] but the connection will not proceed unless user agree to the required information when attempting to connect to the affiliate in the ifree app. User information for the ifree service can be provided with the consent of the user.

Callback URL setting

ifree login is processed by sending and receiving information between the service server and the ifree server. The ifree login will proceed with the first service connection before authentication. The ifree server forwards the information needed to connect to the service through a Callback URI registered with the service server. If the callback URI is not registered, an error occurs when connecting to the service.
