  Zoho Books is online accounting software for small and growing businesses
  that handles invoicing, expenses, banking, projects, inventory, vendor
  bills, reporting, and end-to-end GST/VAT compliance. It is part of the
  Zoho Finance suite and integrates with the rest of the Zoho One platform
  alongside payment gateways, banks, and tax authorities. The Zoho Books
  REST API exposes the full accounting data model — contacts, invoices,
  estimates, expenses, bills, banking, items, taxes, and reports — using
  OAuth 2.0 (Zoho-oauthtoken) for authentication and per-region data
  center base URLs.

    description: >-
      The Zoho Books REST API v3 provides full programmatic access to the
      Zoho Books accounting data model including contacts, invoices,
      estimates, sales orders, purchase orders, bills, expenses, banking,
      items, taxes, projects, and financial reports. Authentication uses
      OAuth 2.0 with the Zoho-oauthtoken header, and base URLs vary by
      regional data center (.com, .eu, .in, .com.au, .jp, .ca, .com.cn,
      .sa). Standard pagination, filtering, and rate limiting are
      supported with up to 100 requests per minute per organization.
