Every item within Deskpro has an ID number. The most commonly-used example is the ticket ID, but there are IDs for most items you can create as an admin: triggers, SLAs, apps, custom fields, etc.
Knowing these IDs is useful when checking or troubleshooting your helpdesk automation by viewing the full log of a ticket. You can see which actions and processes have changed the ticket properties, but they are referred to by ID number.
You can find out which ID belongs to which item from the admin page where you manage that item type.
Click the gear at the top right of the list of items, then enable Show IDs.
This is an example of how trigger IDs are displayed when Show IDs is enabled:
You will also need these IDs when you are referring to a particular item using a variable: for example, within a snippet (in the agent interface), when editing templates, or when you are creating a custom report in the Reports interface.
