# List customers for the authenticated client



## OpenAPI

info:
  title: SVRN Sequential Client API
  version: '2026-04-27'
  description: >-
    OpenAPI spec generated from scripts/dux_requests and the current Lambda
    handlers. This reflects the real sequential client flow used by DUX and
    corrects the main mismatches in the published docs: POST /auth authenticates
    with X-Client-Id and X-Client-Secret headers, POST
    /onboarding/{customer_id}/create-bank-account is the active bank-account
    route, POST /due-diligence/init returns a due_diligence_id plus
    contracts_preview while upload URLs are requested separately via POST
    /due-diligence/{due_diligence_id}/uploads, and due diligence signature
    confirmation is not a client API step because it is performed by the signer
    through an emailed link outside the integrator flow.
