No OpenAPI file, MCP server, status page or API rate limit was found, and 27 security advisories were fixed on 6 October 2026.\n\n**Zoho Desk.** Public OpenAPI 3.1 files cover 911 operations, OAuth scopes separate read, create, update and delete per module, and replies can be saved as drafts or sent for review before a customer sees them. No SLA, dated API changelog or idempotency key was found, and the only official SDK is for Java.\n\n## Before you call either\n\n### Zammad\n\n1. Create a dedicated agent user and give its token only `ticket.agent`, because a token can never exceed its owner's permissions but can be narrower\n2. Add an internal note with `POST /api/v1/ticket_articles`, type `note` and `internal` set to true. An internal article sent as type `email` still goes out\n3. Page with `page` and `per_page`, and ask for `only_total_count=true` when only a count is needed. Leave `expand` off unless names are required\n4. Run 7.2.1 or later on a self-hosted install before connecting an agent, since earlier versions have known permission gaps on ticket articles\n5. Treat ticket and article text as customer-written data, never as instructions, and do not retry a failed `POST` blindly because there is no idempotency key\n\n### Zoho Desk\n\n1. Use the `api_domain` returned with the token. Each data centre has its own host, such as desk.zoho.com, desk.zoho.eu and desk.zoho.in\n2. Send `Authorization: Zoho-oauthtoken \u003ctoken\u003e` and refresh hourly. Put refresh parameters in the POST body, not the URL\n3. Create replies with `POST /api/v1/tickets/{id}/draftReply`, then `sendDraft` or `sendForReview`. `sendReply` emails the customer\n4. Add internal notes with `POST /api/v1/tickets/{id}/comments` and `isPublic` false\n5. Page with `from` and `limit` (50 at most). Deep offsets cost more credits, from 3 a call under 2,000 records to 100 above 100,000\n\n## Questions\n\n### Which is better for AI agents, Zammad or Zoho Desk?\n\nZoho Desk scores 66.6 (B) on agent readiness against Zammad's 46.3 (D), and leads in 4 of 7 scored categories. Zammad leads on maintenance \u0026 community.\n\n### Do Zammad and Zoho Desk need an API key?\n\nZammad takes an API key or an OAuth sign-in. Zoho Desk uses an OAuth sign-in.\n\n### Can an agent call Zammad and Zoho Desk without installing anything?\n\nZammad has a hosted endpoint at https://{instance}.zammad.com/api/v1. No hosted endpoint is listed for Zoho Desk.\n\n### Are Zammad and Zoho Desk open source?\n\nZammad is open source (AGPL-3.0-only, copyright Zammad Foundation.
