# 3DS data-only authentication object

The 3DS data-only authentication object is the `data` of the `issuing.3ds.data_only_received` webhook. A merchant sends a data-only authentication (merchant challenge indicator `06`) to share authentication data without requesting a cardholder challenge, so no 3DS attempt is created.
