How Do Trigger Work =================== Triggers consist mainly of three parts: * **Activator:** defines when and how the trigger has to be evaluated. * **Condition:** defines the tickets for which an action has to be executed based on attributes. * **Actions:** define what to change in a ticket which matches the condition. Triggers are evaluated in alphabetical order by **name.** In some situations, triggers might be the wrong choice, see :doc:`/manage/trigger/limitations` for more information. Activator --------- Choose between an action- or time-based activator in the **Activated by** section. .. figure:: /images/manage/trigger/activator-of-a-trigger.png :alt: Screenshot of activator section in trigger dialog. :scale: 80% :align: center Action ^^^^^^ An action based trigger always requires a ticket update to run. This can be an update by an agent or even internal system updates like updated SLA times. See the explanation below for more details. Selective Checks if any attribute from the condition was updated OR an article was added and the condition matches. If the attributes of the condition weren't touched and no new article was added, the trigger doesn't run. **Example:** A trigger with a condition for priority **1 low** will run if the ticket was changed to **1 low**. Always Checks if the current state of the ticket matches the condition. This means: the trigger always runs when the ticket is updated and the condition matches, no matter what was changed. This can lead to more often executions of such a trigger. **Example:** A trigger with a condition for priority **1 low** will run if the ticket was moved to another group while priority was set **1 low**. .. hint:: If in doubt, use **Selective**. The **Always** action activator can lead to unexpected behavior, e.g. the trigger runs after internal system changes of the ticket, which aren't visible in the ticket history. Time Event ^^^^^^^^^^ The execution is triggered when one of the following events occur: - Time of a reminder is reached - Escalation is reached - Escalation warning is reached When such a time event is reached, the trigger runs if the condition matches. This is the same behavior as action-based activator's "always" mode. Condition --------- Use one or more attributes and values in a condition, which the tickets have to match you want to apply changes to. Create your condition in the **Conditions for affected objects** section: .. figure:: /images/manage/trigger/conditions-of-a-trigger.png :alt: Screenshot of condition section in trigger dialog. :scale: 80% :align: center .. include:: /misc/object-conditions/conditioning-depth-hint.include.rst Action ------ Define which changes to apply for tickets which match your condition in the **Execute changes on objects** section: .. figure:: /images/manage/trigger/actions-of-a-trigger.png :alt: Screenshot of action section in trigger dialog. :scale: 80% :align: center .. hint:: Certain actions (such as email, SMS and notes) support :doc:`/misc/variables` (see screenshot above), which can be used to build highly-customized message templates. A trigger can do the following things once its conditions have been met: Modify the ticket Examples: escalate its priority, close it, reassign it, rename it, add tags, subscribe and unsubscribe specific/all users, etc. Date & time attributes (like **Pending till**) can be specified in *absolute* or *relative* terms. You can also combine static text with placeholders for text fields. Remember that the placeholders' values have to be known during trigger runtime. Learn more about :doc:`/misc/variables`. Send an email or SMS Either to the customer, the agent who owns the ticket, or every agent in the system. Sending emails allows you to include the attachments of the triggering article if required. In order to send emails with triggers, you need to configure an email address for the group, the trigger is working in. If you don't, Zammad will skip the trigger completely. :doc:`Fire a webhook ` Connect Zammad to another web service or application to give it live updates about new tickets. Add internal or public notes to the ticket This allows you to help your agents with specific information if needed. (e.g. automated changes a trigger applied to the ticket) :doc:`Run an AI agent ` Trigger an AI agent to run using triggers. .. _trigger-localization: Localization of Execution Changes --------------------------------- The system locale and timezone predefines a default format of date and timestamp replacement variables. These settings are customizable for triggers. .. figure:: /images/manage/trigger/notification-localization.png :align: center :scale: 90% :alt: Screenshot showing localization section of trigger dialog Best practice is to create single separated localized triggers for each language/timezone and execute them based on user or organization attributes. The format and timezone of date and timestamp replacement variables is customizable by the use of the ``dt()`` method. Further on the ``t()`` method can be used to translated string replacement variables according to the selected locale language. For usage of the ``t()`` and ``dt()`` method, please follow the instructions in the :ref:`variables section `.
