A very (very) simple Webhook implementation in Python

A simple webhook implementation between two different API services

About the app

This apps simulates a user registration in an application which is split between two services:

• A REST API
• A mailing service

When a user registers, a background task (sending the e-mail) is scheduled to run after the request. The API server sends the request with the user's e-mail to the mailing service which then sends the e-mail to the user.

Application flow

Obs: Flowchart made with Mermaid, to visualize is use a markdown editor such as StackEdit.
