Update a ticket

Update a ticket

Changes a ticket's status, priority, assignee, tags or fields, and can add a public reply or an internal note.

Note: A comment with public: true is a reply the requester can see; public: false makes it an internal note. This endpoint has its own rate limit and returns 429 when it runs out.

Set up

Use the first option your agent supports.

API (official)

• Base URL: https://{subdomain}.zendesk.com
• Endpoint: PUT /api/v2/tickets/{ticket_id}
• Auth: send the header Authorization: Bearer $ZENDESK_OAUTH_TOKEN
• Get a key: https://developer.zendesk.com/documentation/authentication/oauth-migration/#getting-your-first-token
• Docs: https://developer.zendesk.com/api-reference/ticketing/introduction/

Note: {subdomain} is your Zendesk subdomain, as in acme.zendesk.com. Tokens from OAuth clients created since April 30, 2026 expire after 30 minutes.

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
