Last updated on June 23, 2025

Introduction

This article walks you through how to activate the profanity filter in your namespace to validate the display names and usernames of your players.

備考

• The profanity filter feature currently only validates the usernames and display names of your players.

Prerequisites

• You have added profane words to the default profanity filter database. See Register and manage default profane words.
• You have created and configured a designated profanity filter Extend App or set up your own custom server.
• You have created custom profanity filters in the Admin Portal. See Create and manage custom profanity filters.

Implement profanity filter with client SDKs

The validate user endpoint is contained inside the User class on both Unity and Unreal SDK.

Validate user input

Unreal SDK

To enable this endpoint, specify the FUserInputValidationRequest model to put it into the parameter function. AGS has several validations including Username, DisplayName, or UniqueDisplayName. If the response is valid, then it will return true. Otherwise, it will return false with an error message.

FUserInputValidationRequest UserInputValidationRequest{};
UserInputValidationRequest.Username = "badwordsexample";
FUserInputValidationResponse UserInputValidationResponse{};

auto ApiClient = AccelByteOnlineSubsystemPtr->GetApiClient(TEXT("YOUR_KEY"));
auto UserApi = ApiClient->GetUserApi().Pin();
UserApi->ValidateUserInput(UserInputValidationRequest, THandler<FUserInputValidationResponse>::CreateLambda([&](const FUserInputValidationResponse& Response)
{
    UE_LOG(LogAccelByteUserServiceTest, Log, TEXT("Success"));
}), FErrorHandler::CreateLambda([&](int32 ErrorCode, const FString& ErrorMessage)
{
    UE_LOG(LogAccelByteUserServiceTest, Warning, TEXT("Error Code: %d, Reason: %s"), ErrorCode, *ErrorMessage);
}));

Unreal OSS

To enable this endpoint, specify the FUserInputValidationRequest model to put it into the parameter function. AGS has several validations including Username, DisplayName, or UniqueDisplayName. If the response is valid, then it will return true. Otherwise, it will return false with an error message.

UserInterface = StaticCastSharedPtr<FOnlineUserAccelByte>(OnlineSubsystem->GetUserInterface());

FUserInputValidationRequest UserInputValidationRequest{};
UserInputValidationRequest.Username = "badwordsexample";
FUserInputValidationResponse UserInputValidationResponse{};
auto ValidateUserInputDelegate = UserInterface->AddOnValidateUserInputCompleteDelegate_Handle(FOnValidateUserInputCompleteDelegate::CreateLambda([&](
    const FUserInputValidationResponse& Response, bool bWasSuccessful, const FOnlineError & OnlineError)
{
    if (bWasSuccessful)
    {
        UE_LOG(LogAccelByteUserInterfaceProfanityFilterTest, Log, TEXT("Success"));
    }
    else
    {
        UE_LOG(LogAccelByteUserInterfaceProfanityFilterTest, Warning, TEXT("Error. Code: %s, Reason: %s"), *OnlineError.ErrorCode, *OnlineError.ErrorMessage.ToString());
    }
}));
UserInterface->ValidateUserInput(LocalUserNum, UserInputValidationRequest);

Unity SDK

// ValidateInputRequest accepts DisplayName, Username, Password, and UniqueDisplayName. If a field is unused or unneeded, you can leave it as null.
Models.ValidateInputRequest request = new Models.ValidateInputRequest()
{
    DisplayName = displayName,
    Username = username
};

Result<Models.ValidateInputResponse> validateResult = null;
AccelByteSDK.GetClientRegistry().GetApi()
    .GetUser()
    .ValidateUserInput(request, result =>
    {
        if (result.IsError)
        {
            // Your code to run when there's an error with the API call
        }

        // Your code to run when the API call is a success
        validateResult = result;
    });
