Create a Sumsub access token
Issues a short-lived Sumsub access token bound to UR's Sumsub tenant, with a fixed 20 minute TTL. Call this after create-account on the SDK path and relay the token to the Sumsub mobile or web SDK on the user device; re-issue a token bound to the same applicant if the user pauses. Requires an active onboarding session on the SDK data channel; X-Ur-Id must be present.
Headers

Your partner-side user id. Send at least one of X-Ur-Id or X-External-User-Id.
Partner Auth EIP-191 signature over the canonical message plus the deadline.
Unix timestamp in seconds after which the signature is no longer valid.
Partner public key used to verify the signature.
Request body
Empty body by design. UR reads urId from the X-Ur-Id header and resolves the active onboarding session server-side.
