Overview

Front Accounting APIs provide programmatic access to an open-source accounting system designed for small businesses. You can manage invoices, customers, and financial transactions across multiple currencies. It is a great starting point if you need to integrate accounting features into a business application.

Beginner Tip

Start by reading the SimpleAPI module documentation carefully, as authentication uses OAuth and requires setting up a client application in your Front Accounting instance first.
