Zoho Books
Zoho Books is Zoho's cloud accounting product, and its REST v3 API exposes the same invoices, expenses, banking feeds, and reports the web app uses, scoped per organization and per Zoho data center (US/EU/IN/etc). Every call needs an OAuth 2.0 access token issued through the shared Zoho Accounts platform used across Zoho's whole suite. A live check against the real API host (www.zohoapis.com) returned no Access-Control-Allow-Origin header, so browser-side calls aren't supported; a permanently free plan exists for very small businesses, with paid tiers unlocking more users and automations.
