# 8.1 Registering a new profile

> Profile registration via API is available only for merchants who have a PCI-DSS certificate.
> If you do not have a PCI-DSS certificate, use registration via the payment link API as described in [5. Creating a new payment link via API], where you need to include the `paywall.forceCardChannel` parameter with an appropriate value.

Registering a new profile via API is done by creating a new card transaction (section 3) with `paymentMethodChannel` set to `oneclick` or `recurring`.

#### Server response

When the transaction is accepted, the standard notification will be returned enriched with an additional `statusCode` field and a `paymentProfile` section with the following structure:

```json
{
    "paymentProfile": {
        "id": "d6a5bd6c-8e9c-496e-beb2-f0ca08215645",
        "merchantMid": "6yt3gjtm9p7b8h9xsdqz",
        "merchantCustomerId": "123",
        "firstName": "Jan",
        "lastName": "Kowalski",
        "maskedNumber": "****1791",
        "month": "10",
        "year": "2020",
        "organization": "MASTERCARD",
        "isActive": 1,
        "profile": "ONE_CLICK"
    }
}
```
