Introduction

The Zoho Books API allows you to perform all the operations that you do with our web client.

Zoho Books API is built using REST principles which ensures predictable URLs that makes writing applications easy. This API follows HTTP rules, enabling a wide range of HTTP clients can be used to interact with the API.

Every resource is exposed as a URL. The URL of each resource can be obtained by accessing the API Root Endpoint.

Organization ID

In Zoho Books, your business is termed as an organization. If you have multiple businesses, you simply set each of those up as an individual organization. Each organization is an independent Zoho Books Organization with it’s own organization ID, base currency, time zone, language, contacts, reports, etc.

The parameter organization_id along with the organization ID should be sent in with every API request to identify the organization.

The organization_id can be obtained from the GET /organizations API’s JSON response. Alternatively, it can be obtained from the Manage Organizations page in the admin console:

Login to the Zoho Books admin console. Click the drop down with organization’s name as the label and click Manage Organizations.

Multiple Data Centers

Zoho Books is hosted at multiple data centers, and therefore available on different domains.

There are 4 different domains for Zoho Books' APIs, and you will have to use the one that is applicable to you.

Data Center Domain Base API URI
United States .com https://books.zoho.com/
Europe .eu https://books.zoho.eu/
India .in https://books.zoho.in/
Australia .com.au https://books.zoho.com.au/
Japan .jp https://books.zoho.jp/

The APIs on this page are for organizations in Zoho Books that are hosted on the .com domain. If your organization is on a different domain, then you must replace .com with the appropriate domain for API endpoints on this page before using them.

Note: To know the domain you're accessing Zoho Books from, visit the Zoho Books web app and check its URL. If the URL contains books.zoho.com, then you're accessing it from the .com domain. If the URL contains books.zoho.in, you're accessing it from the .in domain. Similarly, you could be accessing Zoho Books from the .eu or .com.au or .jp domain.


For example, here's how you would modify the domain in an API endpoint for the .eu domain:

API endpoint for the .com domain, as available on this page:

https://books.zoho.com/api/v3/invoices

API endpoint after replacing the .com domain with .eu:

https://books.zoho.eu/api/v3/invoices
