Long-running background tasks might cause problems for FastAPI apps operating on AWS Elastic Beanstalk. The 502 Bad Gateway error is a frequent issue that is frequently brought on by timeouts in Nginx or Gunicorn. Although it may seem like a solution, raising the timeout settings doesn't always fix the problem. Developers should think about utilizing Celery with Redis or AWS SQS for task queuing and WebSockets for real-time updates in order to efficiently handle background jobs. By avoiding frontend timeouts and guaranteeing API responsiveness and reliability, these techniques preserve a flawless user experience.

A streamlined and creative method for overseeing user registrations and putting verification procedures into place is provided by integrating FastAPI with Google Sheets. With the help of these platforms and Python's capabilities, developers may produce scalable, effective solutions with no overhead.

Sending asynchronous communications straight from web applications is made robust by integrating FastAPI with fastapi-mail.
