Creating an API Checkpoint

How to create your own Flask API on Ubuntu/Linux

Flare and AKoD now use an API instead of pip package for security, and flexibility. Flask API is a type of web API and is designed to make it easy and quick to start building web applications. This API will be used to send a check requests to your auth servers, which should be local, and then return a valid or invalid text.

Setting up a virtual environment in Ubuntu/Linux

1. Create a python virtual environment

   sudo python3 -m venv api

2. Start the venv

   source /api/bin/activate

3. Install the necessary modules

   pip install Flask

   pip install requests

4. Create the main python file

   sudo nano main.py

5. Copy the contents of the AKoDAuth API source code into the file then modify the service to be "webdav"

   svtype = "webdav"

6. Save the file and run the environment

   sudo python3 main.py
