This is my submission to the EBANX home assignment during the inteview process.

Instalation

Made with FastAPI, so you need to install first Python 3 and pip to later install all the necessaries dependencies, if you have installed just run

pip install -r requiremets.txt

then, next run the project

uvicorn main:app --reload

and with that just enjoy.

Implement the following API in the simplest way you can:

Reset state before starting tests

POST /reset 200 OK

Get balance for non-existing account

GET /balance?account_id=1234 404 0

Create account with initial balance

POST /event {"type":"deposit", "destination":"100", "amount":10} 201 {"destination": {"id":"100", "balance":10}}

Deposit into existing account

POST /event {"type":"deposit", "destination":"100", "amount":10} 201 {"destination": {"id":"100", "balance":20}}

Get balance for existing account

GET /balance?account_id=100 200 20

Withdraw from non-existing account

POST /event {"type":"withdraw", "origin":"200", "amount":10} 404 0

Withdraw from existing account

POST /event {"type":"withdraw", "origin":"100", "amount":5} 201 {"origin": {"id":"100", "balance":15}}

Transfer from existing account

POST /event {"type":"transfer", "origin":"100", "amount":15, "destination":"300"} 201 {"origin": {"id":"100", "balance":0}, "destination": {"id":"300", "balance":15}}

Transfer from non-existing account

POST /event {"type":"transfer", "origin":"200", "amount":15, "destination":"300"} 404 0

Where:

Durability IS NOT a requirement, that is, you don’t need to use a database or persistence mechanism. The main goal of this exercise is to create a common ground to conduct the interview process. The API consists of two endpoints, GET /balance, and POST /event. Using your favorite programming language, build a system that can handle those requests, publish it on the internet, and test it using our automated test suite. Keep in mind that:

There is no hidden agenda, if you code passes the tests, and you are happy about it: you are done; Pay attention to the package/directory structure, naming and encapsulation; Separate your business logic from the HTTP transport layer; Keep your code simple, do not try to anticipate anything that is not part of the spec; Keep your code malleable, we may ask for modifications; AGAIN, Keep your code malleable, we may ask for modifications; Use version control, we would love to see your step-by-step process; Take your time, don’t rush it;
