The business
Identified by its registration: legal name, formation country and date, address, and a tax identifier. Its trading profile is part of the check too — industry, purpose, expected volumes — because those are what the check is assessed against. The value sets for each of those fields are in User values.The people tied to it
Each person you list is checked in their own right, with their own identity details and documents. A business is not verified until they are. Who has to be listed is a rule about the business, not about any one person. When someone required is missing,missing_fields names them.
What the API gives you back
missing_fields is the one to build on. It is machine-readable, it names the field rather than describing it, and it is what you show to whoever can supply it — usually your own customer.
Liveness
Some people are additionally asked to complete a liveness check, through a hosted link. Its result arrives onuser.liveness_completed, naming which person completed it, and it is independent of the sub-client’s own status — a liveness result does not move status by itself.
