KYC reuse with Sumsub share tokens

Import existing Sumsub verifications when creating individual customers by passing a share token, skipping document collection for users who already completed KYC on your own Sumsub account.

Reuse an existing Sumsub verification

If your customers already completed KYC on your own Sumsub account, pass a Sumsub share token in the new optional shareToken field when creating a customer to import the existing verification instead of collecting documents again. Lumx detects the verification and reuses it, so onboarding is completed with fewer documents and less waiting.

Availability: KYC reuse is only available for INDIVIDUAL customers at this stage. Business customers (KYB) are not covered, including individual associated parties within a business verification flow. It also requires a data-sharing agreement between you and Lumx. See the KYC Reuse guide for more information.
