Sumsub — Create Transaction (KYT)
Builds a KytTxnData JSON payload from a compact spec, POSTs it to the Sumsub KYT endpoint, and reports the resulting txnId / score / reviewAnswer.
Endpoint
Two variants, picked automatically by the post script:
| Case | Method + Path |
|---|---|
| Applicant exists | POST https://api.sumsub.com/resources/applicants/{applicantId}/kyt/txns/-/data |
Applicant does not exist (Sumsub creates one from applicant.externalUserId) |
POST https://api.sumsub.com/resources/applicants/-/kyt/txns/-/data?levelName=<levelName> |
Body: KytTxnData. Returns the persisted KytTxn with monitoring scores attached.
Both endpoints are marked deprecated, but they remain the canonical "submit transaction" entry points in the official docs. No v2/v3 replacement exists.
