An API key is probably the most common method used by developers to identify what is making the request to an API server, but most developers are not aware how trivial it is for a hacker or even a script kiddie to steal and reuse an API key in order to gain unauthorized access to their APIs.

In the previous article we saw why your mobile app needs an API key, and now we will see how to grab that API key from your mobile app by reverse engineering the binary in an effective and quick way with an open source tool. Once we see how easy it can be done, we will realize that it is even achievable by non-developers.

This walk-though will show us how simple it is to integrate Approov in a current API server using Python and the Flask framework.

We will see the requirements, dependencies and a step by step walk-through over the code necessary to implement Approov in a Python Flask API.

Before we tackle the integration of Approov we need first to know how Approov validation is processed in the server and how to setup the environment to follow this walk-through.

Note that this article assumes a basic understanding of the Approov mechanics. If you need an overview of that, please read first the Approov in Detail page.
