# Zoho Books — Accounting API: overview > Canonical URL: https://developers.apideck.com/apis/accounting/zoho-books/overview Zoho Books is cloud-based accounting software in which you can record, audit and analyze all financial transactions easily. With secure data storage, easy navigation and customizable features, Zoho Books provide a head start in accounting for small businesses. - Status: live - Authentication: oauth2 - **account type required:** Active Zoho Books subscription (Free plan or higher) - **apideck credentials available:** true - **apideck credentials note:** For testing: the OAuth consent screen shows "Apideck"; use your own Zoho OAuth client for production. - **authentication note:** Authorization Code flow. - **beta:** false - **consumer access level:** A user with organization-level access in the Zoho Books organization being authorized - **costs:** Free — Zoho charges nothing for API access on any Zoho Books plan, including the Free plan. - **difficulty:** straightforward - **difficulty reason:** Self-Service OAuth, No Partnership Required - **environment notes:** - **description:** Zoho Books uses the same credentials for testing and production — there is no distinct-credential sandbox tier. To test, start a free Zoho Books trial at https://www.zoho.com/books/signup/ or add a dedicated test organization to your own Zoho Books account. A dedicated test organization is the safer choice during development, since anything else you connect is live production data. - **environment:** Single Environment - **important to know:** Zoho hosts each organization in one of seven regional data centres (US, EU, IN, AU, JP, CA, SA — verified June 2026). Apideck resolves the right region during authorization. A Zoho Books account can hold several organizations and each is authorized separately, so a consumer running three organizations needs three connections. Each consumer's own Zoho Books subscription sets their daily API quota, not yours — you cannot raise it for them. Design syncs around the lowest tier your consumers run on; heavier users unlock more frequent syncs by upgrading their own plan. Refresh tokens never expire, but Zoho stores at most 20 per user: authorizing a 21st silently revokes the oldest, which can break a long-standing connection with no error or warning. - **partnership note:** No partner programme — self-service OAuth client registration is free. An optional Zoho Marketplace listing adds discoverability, not API access. - **partnership required:** false - **rate limits:** 100 requests/minute per organization; daily cap set by the consumer's plan (1,000 Free to 10,000 Premium); 5 concurrent calls on Free, 10 on paid plans. -
