Question

Is it possible to create a technical field that is only accessible via API and completely hidden in the interface?

Answer

Yes. Starting from version 6.0, you can use a technical field that is hidden in the interface and accessible via API. For example, it can store the identifier of a client or object in an external system.

This field is suitable for integration служебные данные that do not need to be shown to the employee or client on the screen. The necessary API permissions and update rules are set in the integration configuration.

Hiding a block or field in the screen layout is a separate setting for the appearance. For the API-only scenario, you need to use a technical field, not just remove the regular field from the screen.
