  from dynaconf import settings
  
  from loguru import logger
  
  
  def get_engine():
      SQLALCHEMY_DATABASE_URL = settings.SQLALCHEMY_DATABASE_URI
  
      engine = create_engine(
          SQLALCHEMY_DATABASE_URL,
      )
      return engine
  
  def get_session():
      _engine = get_engine()
      SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=_engine)
      return SessionLocal
  
  ```
  
  
  **/app/main.py**
  ```python
  from fastapi import FastAPI
  from starlette.middleware.cors import CORSMiddleware
  
  from api.api_v1.api import api_router
  from dynaconf import settings
  
  import logging
  import sys
  from loguru import logger
  
  app = FastAPI(
      title=settings.PROJECT_NAME,
      openapi_url=f"{settings.API_V1_STR}/openapi.json",
      docs_url="/payment-api",
      redoc_url=None
  )
  
  if settings.BACKEND_CORS_ORIGINS:
      app.add_middleware(
          CORSMiddleware,
          allow_origins=[str(origin) for origin in settings.BACKEND_CORS_ORIGINS],
          allow_credentials=True,
          allow_methods=["*"],
          allow_headers=["*"],
