Project Description

The developed API, constructed on Django Rest Framework (DRF), serves the primary function of creating financial reports for businesses using the fortnox.se platform. This sophisticated system is capable of interacting with third-party APIs, generating PDF files, and implementing Google registration/authorization.

The system is versatile, accommodating two distinct user roles: managers and administrators. Depending on the role, users are granted varying degrees of access and control over the functionalities.

In terms of technology, the system leverages an extensive toolkit, each contributing to the overall efficiency and effectiveness of the service. Below are the technologies utilized:

Backend Framework and Environment:

• Django: A high-level Python framework that encourages rapid development and pragmatic design.
• Docker: An open platform for developing, shipping, and running applications, ensuring consistent environments.

API and Filtering:

• Djangorestframework: A powerful and flexible toolkit for building Web APIs.
• Django-filter: A generic system for filtering Django QuerySets based on user selections.
• Coreapi: A format-independent Document Object Model for representing Web APIs.

Google Services:

PDF Generation:

• Reportlab: Allows rapid creation of rich PDF documents.
• Pdfkit: A Python wrapper for Wkhtmltopdf, making it easy to convert HTML to PDF.
• Pypdf2: A library capable of splitting, merging, and transforming PDF pages.
