   ADMIN_EMAIL=admin_email
   ADMIN_USERNAME=admin_username
   ADMIN_PASSWORD=securepassword
   
   # Database URL
   DATABASE_URL=database_uri

🚀🚀 Ready to launch your API Endpoints

4. Run uvicorn server:

   uvicorn api.main:app --reload 

API's

   /auth/register
   /auth/login

   POST /event/ 
   GET /events/ 
   GET /events/{event_id}
   POST /events/{event_id}/book
   GET /success
   GET /cancel

🚀🚀 Test all API's using pytest

5. Run API testing :

   pytest 

Postman Collection

A Ookla-Event-API.postman_collection.json file is included for easy testing of the API endpoints with Postman. Simply import this file into Postman to get started.

API Postman collection

• It has all the api's endpoint with request and response
• You can import it in postman and use it to test the api's

Enhancement

• Security

  • Encryption of data passing to PayPal payment url
    • currently it looks like ***https://sandbox.paypal.com/payment_id=111,event_id=1,token=jklncjbda,booking_id=2*** data can be easily readable to any user including jwt token
    • after encryption with secure key it will look like https://sandbox.paypal.com/payment_id=111,event_id=1,token=VEADdaljbnjkac,booking_id=bjac basically not readable and hard to break

• Database refresh using time or Message broker

  • Currently what if payment link is generated but user has not clicked (canceled / succeed) payment
  • our database doesn’t know about that which can lead us to inaccurate data

• Limitation

  • Limiting the quantity of bookings per user , per event , etc
