# CIN Confirm

> Confirm the CIN selected from the search results to complete company identity verification.

Confirms the CIN you selected from the [CIN Search](/sub-accounts/kyc/cin-search) results. Pass the `company_name` and the chosen `selected_cin`.

<Info>
  Authenticate with your **parent main account's** `X-Auth-ID` and `X-Auth-Token` — the same credentials used everywhere else in the API.

## Request body

| Field          | Type   | Required | Description                                                                         |
| -------------- | ------ | -------- | ----------------------------------------------------------------------------------- |
| `company_name` | string | Yes      | The company name (should match the chosen search result).                           |
| `selected_cin` | string | Yes      | The exact `cin` chosen from the [CIN Search](/sub-accounts/kyc/cin-search) results. |

## Response example

```json 200 OK theme={null}
{
  "verification_type": "cin",
  "status": "verified",
  "cin": "U72900KA2024PTC123456"
}
```

<Note>
  Pass the `selected_cin` **verbatim** from a search result — don't hand-type it. Confirming a CIN that wasn't returned by search will not verify. This step persists the `cin` verification and recomputes `kyc_calls_blocked`.
</Note>
