We have a custom app that pulls data from an external system. This data is mapped to a custom field on our ticket form. When a ticket is created the custom field has a default value. This field value is changed via the mapping and the new value is visible when viewing the ticket. The issue is that the value changing is not actually applied to the ticket since there has been no update to the ticket. It is the same as changing a field value manually and never clicking "submit".
How would we go about forcing an update to the ticket so that the new value is applied?
The new value is applied once the ticket is updated but we need this to happen when the ticket is created or immediately after.
