This is the reference documentation for the Zendesk Support API, which is also known as the Ticketing API. You can use the Support API with tickets, users, organizations, custom objects, and manage ticket workflows.

Any general mechanisms and conventions, such as pagination and authentication, work as described in the Zendesk API introduction and are considered implied in this text.

In addition to the reference docs, the following resources are available:

Run in Postman

If you use Postman, you can import the Support API endpoints as a collection into your Postman app, then try out different requests to learn how the API works. Click the following button to get started:

The Ticketing API lets you specify an idempotency key that allows you to retry a ticket creation request without the risk of creating duplicate records.

To specify an idempotency key, provide a Idempotency-Key: {unique_key} header with your request.


curl https://{subdomain} \  -d '{"ticket": {"subject": "Printer offline", \  "comment": { "body": "My printer is offline. Restarting doesn’t help." }}}' \  -H "Content-Type: application/json" -H "Idempotency-Key: 12345" \  -v -u user:password -X POST

This creates the following response, which also includes a x-idempotency-lookup: miss header:

Status 201 Created{  "ticket": {    "url": "https://{subdomain}",    "id": 3,    "subject": "Printer offline",    ...  }}

If you repeat the same request using the same body and idempotency key, another ticket is not created. Instead, you'll get the same response as before that is cached under the idempotency key. This time the response includes a x-idempotency-lookup: hit header:

Status 201 Created{  "ticket": {    "url": "https://{subdomain}",    "id": 3,    "subject": "Printer offline",    ...  }}

If you create a request using the same idempotency key but with a different body, you'll receive the following error:

400 Bad Request:{    "error": "IdempotentRequestError",    "description": "Request parameters don't match the given idempotency key"}

Keys expire after two hours. If a request with a duplicate key is sent two hours after the original request, the request will create a new ticket.

The idempotency key is not stored as part of the ticket response. You will not be able to see the key when the ticket is opened.
