Design

I used flask to deploy this small API for credit policies, project contains a simple app.py, Dockerfile, docker-compose.yml, and a requirements.txt. It's a simple rest API which can return all of the reasons for credit rejection. I used a decorator for the /ceredit-policies API to catch exception and return a meaningfull response.

I choose to keep the API simple for now, but I could have made an authentication system to send requests and save data to related users if they got accepted to use in further processes.

Installation

1: clone the project in to your device or server

2: go into project directory

3: run command sudo docker-compose up

4: send your requests to http://localhost/credit-policies or http://localhost:5000/credit-policies
