Cross-service event contracts for GDPR operations. Contains event definitions for user deletion, data export, and deletion confirmation workflows.

Installation

dotnet add package Messaging.Contracts

Usage

Reference this package in any service that needs to publish or consume GDPR-related events:

using Messaging.Contracts.Events;

// Publish a user deleted event (from IdentityService)
var evt = new UserDeletedEvent
{
    UserId = userId,
    TenantId = tenantId,
    DeletedAt = DateTime.UtcNow,
    DeletionType = "gdpr_request"
};

// Consume in each service via MassTransit IConsumer<UserDeletedEvent>

Events

Event Details

UserDeletedEvent

Published when a user's account deletion grace period has expired and the deletion is being executed. All services consume this to clean up user-specific data.

public sealed record UserDeletedEvent
{
    public required Guid UserId { get; init; }
    public required Guid TenantId { get; init; }
    public required DateTime DeletedAt { get; init; }
    public required string DeletionType { get; init; }  // "gdpr_request" or "admin_action"
}

UserDataExportRequest

Published by IdentityService to all services using MassTransit Request/Reply (Scatter-Gather) to collect user data for a GDPR data export.

public sealed record UserDataExportRequest
{
    public required Guid CorrelationId { get; init; }
    public required Guid UserId { get; init; }
    public required Guid TenantId { get; init; }
}

UserDataExportResponse

Response from each service containing the user's data. Each service queries its own database and returns the results as JSON.

public sealed record UserDataExportResponse
{
    public required Guid CorrelationId { get; init; }
    public required string ServiceName { get; init; }
    public required bool Success { get; init; }
    public string? ErrorMessage { get; init; }
    public required string DataJson { get; init; }
    public required int RecordCount { get; init; }
}

DeletionConfirmationEvent

Published by IdentityService to trigger a confirmation email via NotificationService when a user requests account deletion.

public sealed record DeletionConfirmationEvent
{
    public required Guid UserId { get; init; }
    public required Guid TenantId { get; init; }
    public required string Email { get; init; }
    public required string ConfirmationUrl { get; init; }
    public required DateTime ExpiresAt { get; init; }
}
