We previously released the possibility to set an external unique ID on each section when synchronizing data with CV Partner through the API.
If set, the unique ID on the section is now shown in the User Interface;
Previous update and how to set this field via the API:
Each section in the CV now has an external unique identifier you can set via the API. The field has to have a unique value within each section type.
When adding or updating each section in the CV this new field can be used to identify which section is externally managed and then could be used to synchronise from another system using a custom integration.
