Customer events track the KYC/KYB onboarding lifecycle of a customer. Subscribe to them to keep your onboarding UI and compliance workflows in sync.

​
Populated fields

Each customer event populates accountId and, depending on the customer type, userId (individual) or entityId (entity). beneficiaryId is set when the event concerns a specific associated person of an entity. The provider field indicates the source of the change (for example sumsub or bridge).
