What is Public ID in guidewire PC integration

Question

Why we use public ID in guidewire integration. Please explain I am new to guidewire. What is importance of Public ID with example.

Answer 1

PublicID is an unique identifier (like a Primary Key), in your integration may be the ID of that object in the remote system (PC, BC, CC, AB).

Answer 2

Following the Guidewire documentation, the PublicID is:

For Guidewire business entities, the PublicID property is the main key property that identifies the entity to an external system. Typically an external system needs the PublicID property, but only if there is a reason to export the object. For example, if important property changed on it or the object is new or added to an entity array. For an incremental export (only changed data), if an entity does not change and no subobject changes, Gosu does not export the object.
