Namespace
Namespace
A Namespace allows multiple independent instances of the same service within a single project by separating data spaces and usage contexts. Each GS2 service is managed on a per-namespace basis. Even when using the same service, if the namespace differs, the data is treated as a completely independent data space.
Therefore, you must create a namespace before you can start using each service.

Transaction Setting
Transaction Setting controls how transactions are executed, including their consistency, asynchronous processing, and conflict avoidance mechanisms. Combining features like AutoRun, AtomicCommit, asynchronous execution using GS2-Distributor, batch application of script results, and asynchronous Acquire Actions via GS2-JobQueue enables robust transaction management tailored to game logic.
| Type | Condition | Required | Default | Value Limits | Description | |
|---|---|---|---|---|---|---|
| enableAutoRun | bool | false | Whether to automatically execute issued transactions on the server side | |||
| enableAtomicCommit | bool | {enableAutoRun} == true | false | Whether to commit the execution of transactions atomically * Applicable only if enableAutoRun is true | ||
| transactionUseDistributor | bool | {enableAtomicCommit} == true | false | Whether to execute transactions asynchronously * Applicable only if enableAtomicCommit is true | ||

ScriptSetting
Script Setting
In GS2, you can associate custom scripts with microservice events and execute them. This model holds the settings for triggering script execution.
There are two main ways to execute a script: synchronous execution and asynchronous execution. Synchronous execution blocks processing until the script has finished executing. Instead, you can use the script’s execution results to halt API execution or control the API’s response content.
In contrast, asynchronous execution does not block processing until the script has finished executing. However, because the script result cannot be used to stop the API execution or modify the API response, asynchronous execution does not affect the API response flow and is generally recommended.
There are two types of asynchronous execution methods: GS2-Script and Amazon EventBridge. By using Amazon EventBridge, you can write processing in languages other than Lua.
| Type | Condition | Required | Default | Value Limits | Description | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| triggerScriptId | string | ~ 1024 chars | GS2-Script script GRN
executed synchronously when the API is executed Must be specified in GRN format starting with “grn:gs2:”. | |||||||||||
| doneTriggerTargetType | String Enum enum { “none”, “gs2_script”, “aws” } | “none” | How to execute asynchronous scripts Specifies the type of script to use for asynchronous execution. You can choose from “Do not use asynchronous execution (none)”, “Use GS2-Script (gs2_script)”, and “Use Amazon EventBridge (aws)”.
| |||||||||||
| doneTriggerScriptId | string | {doneTriggerTargetType} == “gs2_script” | ~ 1024 chars | GS2-Script script GRN
for asynchronous execution Must be specified in GRN format starting with “grn:gs2:”. * Applicable only if doneTriggerTargetType is “gs2_script” | ||||||||||
| doneTriggerQueueNamespaceId | string | {doneTriggerTargetType} == “gs2_script” | ~ 1024 chars | GS2-JobQueue namespace GRN
to execute asynchronous execution scripts If you want to execute asynchronous execution scripts via GS2-JobQueue instead of executing them directly, specify the GS2-JobQueue namespace GRN. There are not many cases where GS2-JobQueue is required, so you generally do not need to specify it unless you have a specific reason. * Applicable only if doneTriggerTargetType is “gs2_script” |
NotificationSetting
Push Notification Settings
This is a setting for sending push notifications when an event occurs in a GS2 microservice. The push notification here refers to the processing via the WebSocket interface provided by GS2-Gateway, and is different from the push notification of a smartphone. For example, when a matchmaking is completed or a friend request is received, the GS2-Gateway can send a push notification via the WebSocket interface, and the game client can detect the change of the state.
GS2-Gateway’s push notifications can be used to forward notifications to mobile push notification services when the destination device is offline. By properly utilizing mobile push notifications, you can implement a flow in which players are notified even if they exit the game during matchmaking and later return to it.
| Type | Condition | Required | Default | Value Limits | Description | |||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| gatewayNamespaceId | string | “grn:gs2:{region}:{ownerId}:gateway:default” | ~ 1024 chars | GS2-Gateway namespace to use for push notifications Specify the GS2-Gateway namespace ID in GRN format starting with “grn:gs2:”. | ||||||||
| enableTransferMobileNotification | bool? | false | Whether to forward the notification as a mobile push notification When this notification is sent and the destination device is offline, specify whether to forward it as a mobile push notification. | |||||||||
| sound | string | {enableTransferMobileNotification} == true | ~ 1024 chars | Sound file name to be used for mobile push notifications The sound file name specified here is used when sending mobile push notifications, and you can send notifications with a special sound. * Applicable only if enableTransferMobileNotification is true | ||||||||
| enable | String Enum enum { “Enabled”, “Disabled” } | “Enabled” | Whether to enable push notifications
|
LogSetting
Log Output Setting
Log Output Setting defines how log data is exported. This type holds the GS2-Log namespace identifier (Namespace ID) used to export log data. Specify the GS2-Log namespace where log data is collected and stored in the GRN format for the Log Namespace ID (loggingNamespaceId). Configuring this setting ensures that log data for API requests and responses occurring within the specified namespace is output to the target GS2-Log namespace. GS2-Log provides real-time logs that can be used for system monitoring, analysis, debugging, and other operational purposes.
| Type | Condition | Required | Default | Value Limits | Description | |
|---|---|---|---|---|---|---|
| loggingNamespaceId | string | ✓ | ~ 1024 chars | GS2-Log namespace GRN
to output logs Must be specified in GRN format starting with “grn:gs2:”. |
CurrentMessageMaster
Currently active Global Message master data
This master data describes the definitions of Global Messages currently active within the namespace. GS2 uses JSON format files for managing master data. By uploading these files, the master data settings are updated on the server.
To create JSON files, GS2 provides a master data editor within the management console. Additionally, you can create tools better suited for game operations and export JSON files in the appropriate format.
Note
Please refer to GS2-Inbox Master Data Reference for the JSON file format.Request

Global Message
Global Message is a mechanism for delivering messages to all game players.
Global messages can have an expiration time, and each game player can receive a Global Message by executing the process of receiving a Global Message. Unreceived Global Messages within the validity period are copied to the player’s message box.
| Type | Condition | Required | Default | Value Limits | Description | |
|---|---|---|---|---|---|---|
| globalMessageId | string | * | ~ 1024 chars | Message GRN
to all users * Set automatically by the server | ||
| name | string | ✓ | ~ 128 chars | Global Message name Global Message-specific name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.). | ||
| metadata | string | ✓ | ~ 4096 chars | Metadata Arbitrary data representing the global message content, such as a JSON string containing the message title, body text, and display parameters. When a user receives this global message, the metadata is copied to the individual message in their inbox. GS2 does not interpret this value. Maximum 4096 characters. | ||
| readAcquireActions | List<AcquireAction> | [] | 0 ~ 100 items | Read Acquire Actions The list of acquire actions to be executed when a user opens the message copied from this global message. These actions are copied along with the metadata to each user’s individual message. Up to 100 actions per global message. | ||
| expiresTimeSpan | TimeSpan | Expiration Time Span The duration from the time a user receives (copies) this global message until the copied message expires and is automatically deleted from their inbox. Specified as a combination of days, hours, and minutes. Messages are deleted regardless of read status when the expiration is reached, including any unclaimed attached rewards. | ||||
| messageReceptionPeriodEventId | string | ~ 1024 chars | Message Reception Period Event ID The GRN of a GS2-Schedule event that defines the time window during which this global message can be received (copied to users’ inboxes). Outside this period, the global message is not delivered even if a user triggers the receive global messages operation. Useful for time-limited event announcements or seasonal campaign rewards. |
TimeSpan
Time Span
Represents a duration of time as a combination of days, hours, and minutes. Used to define the expiration period for messages relative to their reception time. For example, a TimeSpan of 7 days, 0 hours, 0 minutes means the message expires exactly one week after the user receives it.
| Type | Condition | Required | Default | Value Limits | Description | |
|---|---|---|---|---|---|---|
| days | int | 0 | 0 ~ 365 | Days The number of days in this time span. Combined with hours and minutes to calculate the total duration. Maximum 365 days. | ||
| hours | int | 0 | 0 ~ 24 | Hours The number of hours in this time span. Combined with days and minutes to calculate the total duration. Maximum 24 hours. | ||
| minutes | int | 0 | 0 ~ 60 | Minutes The number of minutes in this time span. Combined with days and hours to calculate the total duration. Maximum 60 minutes. |
AcquireAction
Acquire Action
Represents a single acquire action attached to a message as a reward. Consists of an action type (e.g., add items to inventory, increase currency) and its request parameters. When a message is opened, these actions are assembled into transactions and executed to deliver the rewards to the user.
