# Hand off a Sumsub share token

Submits a single-use Sumsub share token minted in your tenant for UR's clientId. UR copies the applicant into its own Sumsub tenant, validates the copied data, and returns a conclusive verdict synchronously; UR does not re-run the KYC checks. Requires an onboarding session created by create-account and a GREEN applicant in your tenant. The envelope code is authoritative: passed maps to 0, incomplete to 20004, and terminal verdicts to eligibility codes 30010 to 30012.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ur.app/api-reference/api/kyc-and-kyb/managed-custody-kyc/hand-off-a-sumsub-share-token.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
