• Action required: Migrate your customer integration to API v1

  ⚠️ The customer resource has been redesigned in API v1 and the v0 version will be deprecated on June 12, 2026. Any integration that depends on the v0 customer endpoint will stop working after that date.

  API v1 introduces a redesigned customer creation flow with two verification paths. Option A uses the Sumsub hosted flow: your application redirects the user to the verification_link returned by POST /v1/customers and verification completes without additional API calls. This is the fastest path and the one we recommend for most cases. Option B gives full control over the UI and document collection via direct API upload, intended for partners who need a fully customized experience.

  For full migration details, refer to the Customer guide.
