This article explains how to set ticket properties and specify actions when creating and updating a ticket. For reference information, see the Tickets resource in the Ticketing API reference.

Creating a follow-up ticket

Once a ticket is closed (as distinct from solved), it can't be reopened. However, you can create a new ticket that references the closed ticket. To create the follow-up ticket, include a via_followup_source_id parameter that specifies the closed ticket. Example:

curl https://{subdomain}.zendesk.com/api/v2/tickets.json \  -d '{"ticket": {"via_followup_source_id": 103, "comment": {"body": "My printer is still too hot!"}}}' \  -v -u {email_address}:{password} -X POST -H "Content-Type: application/json"

The parameter only works with closed tickets. It has no effect with other tickets.

By default, the first comment author is the authenticated user making the API request. To set a different author, include an author_id property in the comment object.

Creating a ticket asynchronously

Ticket creation can sometimes take a while because of complex business rules. Asynchronous creation allows you to get the response back quickly and queues a background job to do the actual work.

To make an asynchronous request, simply add the parameter async in your request:

POST api/v2/tickets.json?async=true

As soon as the request is received, it returns a 202 Accepted. The response includes the new ticket id with a job_status JSON object. However, you may not be able to fetch the ticket until the job is done.

Note: Some ticket id numbers may get skipped if ticket creation fails.

Setting collaborators

Note: If the CCs and Followers feature is enabled for the account, using email CCs and followers is preferred. See Setting email CCs and Setting followers. You can still set collaborators with the collaborators and additional_collaborators ticket properties described in this section. They'll automatically make end users CCs and agents followers.

When creating or updating a ticket, you can set collaborators on a ticket using one of three properties: collaborator_ids, collaborators or additional_collaborators. The collaborators property provides more flexibility, as outlined below.

An email notification is sent to the collaborators when the ticket is created or updated.

Setting collaborators or collaborator_ids when updating a ticket replaces existing collaborators. Make sure to include existing collaborators in the update request if you want to retain them on the ticket. If you only want to add more collaborators, use additional_collaborators instead.

The collaborator_ids property is a basic option that takes an array of user ids.

Example

{  "ticket": {    "collaborator_ids": [562624, 624562, 243642]  }}

The collaborators property is a more flexible option. It takes an array consisting of a combination of user ids, email addresses, or objects containing a name and email property. For example:

Use an object to create the user on the fly with the appropriate name in Zendesk Support.

Example

{  "ticket": {    "collaborators": [ 562, "[email protected]", { "name": "Someone Else", "email": "[email protected]" } ]  }}

The additional_collaborators property is used to add additional collaborators. It preserves the existing collaborators, and adds new collaborators to the ticket. It takes an array consisting of a combination of user ids, email addresses, or objects containing a name and email property.

Example

{  "ticket": {    "additional_collaborators": [ 562, "[email protected]", { "name": "Someone Else", "email": "[email protected]" } ]  }}

Even if you use the collaborators property, the JSON response will specify the new or updated collaborators as an array of user ids in the collaborator_ids property. The response doesn't have a collaborators property.

Setting followers

When creating or updating a ticket, you can set followers on a ticket using the followers property.

An email notification is sent to the followers when the ticket is created or updated.

The followers property takes an array of objects representing agents. Each object must have an identifier, either user ID (user_id) or email address (user_email). If a user_email or user_id is given which doesn't exist in the account, that user object is ignored. Additionally, the action key can be set to either "put" or "delete" to indicate whether the user should be added to or removed from the followers list. If the action key is not given, the default value is "put".

Example

{  "ticket": {    "followers": [      { "user_id": "562624", "action": "put" },      { "user_id": "624562" },      { "user_id": "243642", "action": "delete" },      { "user_id": "562", "user_email": "[email protected]", "action": "delete" },      { "user_email": "[email protected]", "action": "put" },    ]  }}

Setting email CCs

When creating or updating a ticket, you can set email CCs on a ticket using the email_ccs property.

A single email notification is sent to the requester and CCs when the ticket is created or updated, depending on trigger settings.

The email_ccs property takes an array of objects representing users. Each object must have an identifier, either user ID (user_id) or email address (user_email). If an email address is specified and the user doesn't exist in the account, a new user is created. Additionally, the key action can be set to either "put" or "delete" to indicate whether the user should be added to or removed from the email CCs list. If the action key is not given, the default value is "put". Optionally, if a new user is created, you can specify user_name to set the new user's name. If the user is implicitly created and a user_name is not given, the user name is derived from the local part of the email address. If an email address not associated with a user is included (for example, with the intention to implicitly create the user), but the value of the action key is "delete", that email address is not be created or added as an email CC.

A ticket can only have 48 email CCs. If more than 48 email CCs are included in the request, a "400 Bad Request" will be returned. If existing email CCs and the additional email CCs added through the request add up to more than 48, the email CCs will be truncated to 48 and no error will be reported.

Email CCs will not be updated if an internal note is also added to the ticket in the same update.

Example

{  "ticket": {    "email_ccs": [      { "user_id": "562624", "action": "put" },      { "user_id": "243642": "action": "delete" },      { "user_email": "[email protected]", "user_name": "Someone Else", "action": "put"}    ]  }}

Setting metadata

When you create or update a ticket, an Audit gets generated if the ticket properties have changed. On each such audit, you can add up to 1 kilobyte of custom metadata. You can use this to build your own integrations or apps. Note: If your update does not change the ticket, this will not create an Audit and will not save your metadata.

Example

{  "ticket": {    "metadata": { "time_spent": "4m12s", "account": "integrations" },    "comment":  { "body": "Please press play on tape now" },    "status":   "pending"  }}

Note that metadata can only be set as part of other regular ticket updates as they are associated to, rather than just the ticket. Zendesk Support also adds metadata on each ticket update, and the resulting audit JSON structure looks like this:

{  "audit": {    "id":         35436,    "ticket_id":  47,    "created_at": "2012-04-20T22:55:29Z",    "author_id":  35436,    "metadata": {      "custom": {        "time_spent": "4m12s",        "account": "integrations"      },      "system": {        "ip_address": "184.106.40.75",        "location": "United States",        "longitude": -97,        "latitude": 38,        "client": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3)"      }    },    "via": {      "channel": "web"    },    "events": [      {        "id":          1564245,        "type":        "Comment"        "body":        "Please press play on tape now",        "public":      true,        "attachments": []      },      ...    ]  }}

Attaching files

When creating and updating tickets, you may attach a file to a comment by including a token received from uploading the file.

For details and examples, see Attaching ticket attachments with the API.

Example

{  "ticket": {    "comment":  { "body": "Please press play on tape now", "uploads":  ["vz7ll9ud8oofowy"] }  }}

Creating a ticket with a new requester

You can specify a requester when creating a ticket. A name, email, and locale id can be set for the requester. A name and email are required. For locale ids, see the Locales API.

Example

{  "ticket": {    "subject":   "Hello",    "comment":   { "body": "Some question" },    "requester": { "locale_id": 8, "name": "Pablo", "email": "[email protected]" }  }}

If the requester's identity doesn't exist in Zendesk, a new user profile is created on the user's behalf. The user needs to verify their identity to view their requests.

If a user exists in Zendesk with the specified email address, then Zendesk uses that user and makes no updates to existing users during the ticket creation process. In this approach, only the email attribute is required.

Setting custom field values

To set the value of one or more custom fields in a ticket, specify an array of objects consisting of id and value properties. For text or numeric fields, specify text or numbers for the value property:

"custom_fields": [{"id": 25356371, "value": "I bought it at Buy More."}, ...]

For date fields, specify only the date (formatted as a ISO 8601 string) and omit the time:

"custom_fields": [{"id": 25356634, "value": "2020-02-24"}, ...]

For fields with values defined by tags, such as drop-down lists, specify the option's tag name for the value property, not the option text displayed in the list. For example, if the option's display text is "HD 3000 color printer" and its tag is hd_3000, set the custom field's value as follows:

"custom_fields": [{"id": 21938362, "value": "hd_3000"}]

Multi-select field values are also defined by tags. However, the value property is a comma-separated list. For example, if the values of the tags are hd_3000 and hd_5555, the custom field's values is as follows:

"custom_fields": [{"id": 21938362, "value": ["hd_3000", "hd_5555"]}]

For more information, see Ticket Fields.

Example

{  "ticket": {    "subject": "Hello",    "comment": { "body": "Some question" },    "custom_fields": [{ "id": 34, "value": "I need help!" }]  }}

Protecting against ticket update collisions

As with any database application, it's good practice to guard against record update collisions. If multiple updates to the same ticket are performed almost simultaneously, the updates might collide and result in data loss. For example, take a ticket with two tags, "red" and "blue". One update attempts to append "green" to the list of tags. A separate update attempts to append "yellow". If the two updates are made at almost the same time, the following sequence might unfold:

  1. Update A reads ["red", "blue"]
  2. Update B reads ["red", "blue"]
  3. Update A writes ["red", "blue", "green"]
  4. Update B writes ["red", "blue", "yellow"]

The data "green" is lost because Update B was allowed to proceed with an out-of-date array.

You can make safe updates to prevent updates like Update B from proceeding. In a safe update, you include the last known ticket update with your request to check for more recent updates. If the system detects a ticket update more recent than the last known update, it prevents your update from proceeding and sends a response that lets you know that the ticket wasn't updated. As a developer, you should account for this result and get a fresh copy of the ticket data and try the update again. See Checking if the ticket was not updated below.

To enable safe updates, include the safe_update and updated_stamp properties in the ticket object in your PUT request to check for more recent updates. Example:

{  "ticket": {    "subject": "Updated Subject",    "updated_stamp": "2021-08-24T16:53:51Z",    "safe_update": true,    ...  }}

The value of updated_stamp is the last known time the ticket was updated at the moment you make your update request. The last known time is the time currently specified by the ticket's updated_at​ property. Make a preliminary request to Show Ticket to get this value. For placeholders in webhook workflows, the last known update time is ticket.updated_at_with_timestamp.

When updating many tickets at once, you can also specify safe_update and updated_stamp properties for each ticket object. This protects against ticket update collisions and returns a message to let you know if one occurs.

Checking if the ticket was not updated

When making safe updates, the request returns a 409 status code or an "UpdateConflict" job status to let you know that the ticket was not updated because of a more recent update. It's a signal to get the latest ticket data and retry your update.

When updating a single ticket, instrument your code to look for a 409 status code in the response and handle it accordingly. Example 409 response:

Status: 409 Conflict{   "description": "Safe Update prevented the update due to outdated ticket data.                   Please fetch the latest ticket data and try again.",   "error": "UpdateConflict"}

When updating tickets in bulk or in batch, instrument your code to monitor the job's status for "UpdateConflict" errors and handle it accordingly. Example job status:

{  "job_status": {    "results": [      {        "index": 0        "error": "UpdateConflict",        "id": 9999,        "details": "Safe Update prevented the update due to outdated ticket data. Please fetch the latest ticket data and try again."      }    ],    ...  }}
