We've added the Customer entity which is stored in the H2 in-memory database using Spring Data JPA and POST API endpoint /customer.

• Example POST curl: curl -X POST "http://localhost:8080/customer" -d '{"firstName":"anshul","lastName":"bansal","email":"[email protected]"}' -H "Accept: application/json" \ -H "Content-Type:application/json"

However, when the Customer record is fetched using the GET API, we require to pass the id of the Customer object and the idempotencyKey in the request header. The application will check if the idempotencyKey exist in the Redis cache and tries to fetch the Customer object from the cache else it will search the H2 database.

• Example GET curl: curl "http://localhost:8080/customer?id=281407da-5265-468f-b65b-d98d2268b122" -H "idempotencyKey: 0f3123e5-de97-4d4b-b2d5-e59e8ccfd442"

Notes:

• We've used the UUID for both id and idempotencyKey.
• Use the id of the Customer object received in the response of the POST API.
