Game authentication information​

In order to use BACKND's functions, you need to input the Client App Id and Signature Key in the BACKND SDK.\ For information on how to use them, please refer to the developer documentation - Getting Started.

Issue a new Client App Id/Signature Key​

To get a new Client App Id and Signature Key, click Issue New on the right side of the corresponding field and obtain a new key value.\ Precautions for new issuance are as follows:

  • When changing the Client App Id, you must reconfigure the authentication value in the BACKND SDK, meaning that some settings such as temporary announcements and BACKND chat filter in BACKND Console are also reset.
  • If the Client App Id and Signature Key are reissued, the corresponding values must also be changed in the SDK settings.
  • If the Client App Id is changed in the SDK, the settings stored locally in the BACKND SDK are reset.(Guest login information, user access token information, etc.)

Caution when transferring a game between Apple developer accounts

When transferring a game to another account from the account you first operated on, the Team ID will be changed, bringing upon changes in the unique values (sku of each user) for when users log in. Due to this, you cannot log in using the previous information.

This is due to Apple's policy, and if you wish to provide a stable gaming service, BACKND's paid technical support is necessary.

If you wish to proceed with the transfer, please make an inquiry to the community or help@backnd.com in advance to prevent any inconvenience that may occur when operating your game.\

Android package Name and iOS Bundle Identifier are the values that distinguish applications.\ You can enter different ones for Google Play Store and ONE Store.\ You can check it via File → BuildSettings → PlayerSettings → OtherSettings → package Name on the upper section of the Unity window.

You cannot enter the same package name for both Google Play Store and ONE Store.
You can use the same package name in the two stores only after checking the [Apply the same package name for Play Store and ONE Store.] option.
When the same package name is used, the name is integrated with Google Play Store's package name and managed as such in functions like Add Push Store.

Precautions for when using the same package name

When using or removing the same package name in Google Play Store and ONE Store, the reserved/repeated push messages are canceled, and authentication information registered to certain functions that use the package name such as Push Store Information may be deleted. This is due to Apple's policy, and if you wish to provide a stable gaming service, BACKND's paid technical support is necessary.

Google Hash Key is the key used in communication between the BACKND server and the Google server in an Android environment.\ This key allows you to use validation and Google-related functions.

iOS Bundle Identifier is a value that distinguishes applications.\ You can also enter the iOS Bundle Identifier for web login.\ You can check it via File → BuildSettings → PlayerSettings → OtherSettings → package Name on the upper section of the Unity window.

iOS Bundle Identifier for Web Login is the Services ID value for SignInWithApple, which you need to enter if you’re implementing Apple login on Android using the BACKND Apple Login SDK for Android.

Apple Developer Account's Team ID is required for the Apple token expiration REST API call, which is used when a user withdraws membership. This is the Team ID of the Apple developer account that owns the app.

Apple Project Key Name is also needed for the token expiration REST API call. This is the name of the key that was issued to access the "Sign in with Apple" service linked to the app.

Apple Project Key (P8 file) is the key itself, issued to access the "Sign in with Apple" service, and is also required for the Apple token revocation REST API.

For instructions on how to input the three Apple values needed for account withdrawal, refer to the Developer Documentation - Apple Token Expiration.
