# Working with APIs

> Platform basics, TLS requirements, maker-checker model, and shared conventions

**About Zodia API**

* Zodia's API is RESTful over HTTPS and consumes JSON payload
* Transport level security is TLS 1.2.
* Requests must be digitally signed using company private key i.e. SHA256withRSA (minimum 2048 bits)
* Zodia's API requires at least two users: a **maker** (creation request) and a **checker** (approval request)
* The examples below in Python require the libraries:
  * **cryptography** that can be installed with pip: `pip install cryptography`
  * **requests** that can be installed with pip: `pip install requests`
