Implemented comprehensive multi-tenant data isolation using database-level security - Built JWT authentication system with role-based access control (Super Admin, Org Admin, User, Viewer) - Created RESTful API endpoints for user and organization operations - Added complete audit logging for all data modifications with IP tracking - Implemented API rate limiting and input validation with security middleware - Built webhook processing engine with async event handling and retry logic - Created external API call handlers with circuit breaker pattern and error handling - Implemented data synchronization between external services and internal data - Added integration health monitoring and status tracking - Created three mock external services (User Management, Payment, Communication) - Implemented idempotency for webhook processing to handle duplicates gracefully - Added comprehensive security headers and XSS/CSRF protection - Set up Alembic database migrations with proper SQLite configuration - Included extensive documentation and API examples Architecture features: - Multi-tenant isolation at database level - Circuit breaker pattern for external API resilience - Async background task processing - Complete audit trail with user context - Role-based permission system - Webhook signature verification - Request validation and sanitization - Health monitoring endpoints Co-Authored-By: Claude --- README.md | 397 +++++++++++++++++- alembic.ini | 118 ++++++ alembic/env.py | 83 ++++ alembic/script.py.mako | 26 ++ alembic/versions/001_initial_migration.py | 142 +++++++ app/api/endpoints/auth.py | 37 ++ app/api/endpoints/health.py | 56 +++ app/api/endpoints/integrations.py | 117 ++++++ app/api/endpoints/organizations.py | 43 ++ app/api/endpoints/users.py | 109 +++++ app/api/endpoints/webhooks.py | 82 ++++ app/api/v1/api.py | 11 + app/core/config.py | 41 ++ app/core/deps.py | 105 +++++ app/core/security.py | 35 ++ app/db/base.py | 3 + app/db/session.py | 16 + .../external_apis/circuit_breaker.py | 94 +++++ app/integrations/external_apis/client.py | 213 ++++++++++ app/integrations/webhooks/handlers.py | 166 ++++++++ app/middleware/rate_limit.py | 33 ++ app/middleware/validation.py | 99 +++++ app/models/__init__.py | 23 + app/models/audit.py | 32 ++ app/models/integration.py | 71 ++++ app/models/tenant.py | 20 + app/models/user.py | 33 ++ app/schemas/auth.py | 27 ++ app/schemas/organization.py | 32 ++ app/schemas/user.py | 39 ++ app/schemas/webhook.py | 54 +++ app/services/audit.py | 80 ++++ app/services/auth.py | 124 ++++++ app/services/integration.py | 314 ++++++++++++++ app/services/organization.py | 109 +++++ app/services/user.py | 175 ++++++++ app/services/webhook.py | 274 ++++++++++++ main.py | 110 +++++ mock_services/communication_service.py | 206 +++++++++ mock_services/payment_service.py | 156 +++++++ mock_services/user_service.py | 118 ++++++ requirements.txt | 19 + 42 files changed, 4040 insertions(+), 2 deletions(-) create mode 100644 alembic.ini create mode 100644 alembic/env.py create mode 100644 alembic/script.py.mako create mode 100644 alembic/versions/001_initial_migration.py create mode 100644 app/api/endpoints/auth.py create mode 100644 app/api/endpoints/health.py create mode 100644 app/api/endpoints/integrations.py create mode 100644 app/api/endpoints/organizations.py create mode 100644 app/api/endpoints/users.py create mode 100644 app/api/endpoints/webhooks.py create mode 100644 app/api/v1/api.py create mode 100644 app/core/config.py create mode 100644 app/core/deps.py create mode 100644 app/core/security.py create mode 100644 app/db/base.py create mode 100644 app/db/session.py create mode 100644 app/integrations/external_apis/circuit_breaker.py create mode 100644 app/integrations/external_apis/client.py create mode 100644 app/integrations/webhooks/handlers.py create mode 100644 app/middleware/rate_limit.py create mode 100644 app/middleware/validation.py create mode 100644 app/models/__init__.py create mode 100644 app/models/audit.py create mode 100644 app/models/integration.py create mode 100644 app/models/tenant.py create mode 100644 app/models/user.py create mode 100644 app/schemas/auth.py create mode 100644 app/schemas/organization.py create mode 100644 app/schemas/user.py create mode 100644 app/schemas/webhook.py create mode 100644 app/services/audit.py create mode 100644 app/services/auth.py create mode 100644 app/services/integration.py create mode 100644 app/services/organization.py create mode 100644 app/services/user.py create mode 100644 app/services/webhook.py create mode 100644 main.py create mode 100644 mock_services/communication_service.py create mode 100644 mock_services/payment_service.py create mode 100644 mock_services/user_service.py create mode 100644 requirements.txt diff --git a/README.md b/README.md index e8acfba..1daf559 100644 --- a/README.md +++ b/README.md @@ -1,3 +1,396 @@ -# FastAPI Application +# Multi-Tenant SaaS Platform with External Integrations -This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform. +A comprehensive backend system that combines multi-tenant SaaS platform features with external API integration capabilities.
