Zoho CRM V8 APIs are RESTful APIs for programmatic access to CRM data and metadata. V8 is the current generation (Zoho CRM V8 API documentation).
API Categories
| Category | Description |
|---|---|
| Metadata APIs | Fetch module list, field schemas, layouts, custom views, related lists |
| Core APIs | Full CRUD on all module records; flexible RESTful endpoints |
| Composite API | Combine up to 5 API calls in a single HTTP request |
| Bulk APIs | Asynchronous push/pull of large record sets |
| Notification APIs | Subscribe to real-time record change events |
| Query APIs (COQL) | SQL-style SELECT queries against CRM module data |
| GraphQL APIs | Fetch specific fields/relationships efficiently (mentioned in developer docs) |
Authentication
OAuth 2.0 with client credentials (client ID, client secret, redirect URI). Access tokens expire on a configurable schedule; refresh tokens renew access. A Postman collection is provided for all V8 API calls (Zoho CRM V8 API collection).
COQL (CRM Object Query Language)
COQL uses SQL-like SELECT syntax to query CRM records, supporting WHERE, ORDER BY, GROUP BY, and JOIN-equivalent operations across related modules. Used in both the API Query endpoint and within MCP server operations.
