Flask Dynamic API

This tool aims to provide a secure, production-ready API via Flask-RestX using the developer's minimum amount of code. For newcomers, Flask is a leading backend framework used to code from simple websites and API's to complex eCommerce solutions.

Flask-RestX is a popular library for developing secure API services using Flask.

Start the project

$ flask run

✅ How it works

The Dynamic API tool aims to enable a secured API service on top of any Flask codebase with a minimum effort. Here are the steps:

  • Define a new model in the project (an old one can be also used)
  • Execute the database migration to create/update the associated tables
  • Update the configuration to enable the Dynamic API over the model
  • Start the app
  • Access the Dynamic API Service

For instance, if the new model managed by the Dynamic API is called books, the associate API is exposed at /api/books/

New Models Definition in apps/models-
The app is saved in apps/dyn_api-
Models enabled in apps/ via DYNAMIC_API variable-
The project exposes automatically a CRUD API over the new model-
Path of the service: /api/books/In case the new model is Books
The API is powered via Flask-RestX using best practices-

✅ API Permissions

Before using the API, the user must make a request to the `/login' endpoint and send his username and password.:

POST /login
"username": "my_username",
"password": "my_password"

The server returns a token if approved.


To use the features, the user must add a key and value to the headers.

headers of requests:

"Authorization": "token RETURNED_TOKEN"

Note: token will be expired after 24 hours.
