Overview
The Zoho Books API gives you programmatic access to your Zoho Books accounting data, letting you manage invoices, contacts, expenses, and payments from your own apps. It uses OAuth 2.0 for secure authorization and supports both reading and writing data. It is a solid choice for building custom billing workflows or syncing accounting data with other business tools.
Beginner Tip
Use the Zoho API Console to create a Self Client and generate a one-time authorization code — this is the fastest way to get an access token for testing.
