Report offensive messages

Message Persistence

Enable Message Persistence in the Admin Portal.

Users can report offensive messages directly from your app. Reported messages publish to PUBNUB_INTERNAL_ADMIN_CHANNEL and emit report events.

Add custom logic using emitted events to handle reported messages (e.g., delete them).

You can use PubNub's functionality via Blueprints or directly in C++ code.

• In Blueprints, you can access PubNub from any Widget or Actor. Start by initializing chat using InitChat on UPubnubChatSubsystem. Afterwards, you can use the returned UPubnubChat object reference to call all Chat SDK functions.

Blueprint functions

The Blueprints provided in the documentation show how you can structure your application and may contain utility methods and elements like buttons that are not part of the Unreal Chat SDK and are meant to serve as guidance.

• In C++, you can use UPubnubChatSubsystem as any other Game Instance Subsystem.

  Chat now allows you to call all Chat SDK functions, for example, Chat->GetChannel("my_channel").

Usage in Blueprints and C++

Asynchronous and synchronous method execution

Most PubNub Unreal SDK methods are available in both asynchronous and synchronous variants.

• Asynchronous methods (Async suffix) return void and take an optional delegate parameter that fires when the operation completes.

  1Message->ReportAsync(OnReportResponseDelegate, Reason);

  You can also use native callbacks that accept lambdas instead of dynamic delegates. Native callback types have the Native suffix (for example, FOnPubnubChatOperationResponseNative).

• Synchronous methods (no suffix) block the main game thread until the operation completes and return a result struct directly.

  1FPubnubChatOperationResult Result = Message->Report(Reason);

Flag/Report messages

Report() flags a message for admin review.

Stream message report events

StreamMessageReports() subscribes to real-time report events on a channel. Bind the channel's OnMessageReported delegate before calling this method to receive report events.

note

Use this method for channels where you want live monitoring of reported messages, such as an admin moderation dashboard.

Method signature

1Channel->StreamMessageReports();

Bind the channel's OnMessageReported delegate before calling StreamMessageReports() to receive report events.

Output

Type	Description
FPubnubChatOperationResult	Result of the operation. Check Error for failure.

Sample code

Stream report events on the support channel.

Get message reports history

GetMessageReportsHistory() retrieves historical report events from a channel, similar to GetHistory() for messages. Use this to audit past message reports.

Method signature

1Channel->GetMessageReportsHistory(
2    FString StartTimetoken,
3    FString EndTimetoken,
4    int Count = 100
5);

* required

Parameter	Description
StartTimetoken Type: FString Default: n/a	Timetoken delimiting the start of a time slice (exclusive) to pull report events from.
EndTimetoken Type: FString Default: n/a	Timetoken delimiting the end of a time slice (inclusive) to pull report events from.
Count Type: int Default: 100	Number of historical report events to return for the channel in a single call. Maximum: 100.

Output

Parameter	Description
FPubnubChatEventsResult Type: struct	Returned object containing Result, Events, and IsMore.
→ Result Type: FPubnubChatOperationResult	Operation result with Error (bool), ErrorMessage (FString), and StepResults.
→ Events Type: TArray<FPubnubChatEvent>	Array of historical report event objects.
→ IsMore Type: bool	Indicates whether there are more historical events to pull.

Sample code

Fetch the last 10 report events from the support channel.
