# Tilopay.InitTokenize()

> Starts saving a card without a purchase: the card is validated with a USD 0.10 charge that is reversed immediately.

- kind: sdk-method
- status: stable
- sdk_version: 2.1.1
- last_verified: 2026-10-22
- url: https://tilopay.com/en/developers/sdk/reference/init-tokenize

Starts saving a card **without a purchase**. It uses the same
[form fields](/en/developers/sdk/campos-del-formulario) as `Init()` and is closed with
[`Tilopay.startPayment()`](/en/developers/sdk/reference/startpayment).

> **Note:** Validation charge. To validate the card, Tilopay makes a USD 0.10 charge (or its equivalent
> in the currency) that is reversed immediately; the customer sees it refunded within minutes.

Store the token you receive and associate it with the customer's email to use it later.

## Signature [#firma]

Do not send `orderNumber`: the SDK uses its own session identifier. Tilopay sets the validation amount.

```js
await Tilopay.InitTokenize({ /* parameters */ })
```

## Redirect parameters [#parametros-del-redirect]

Redirect query parameters are `code`, `crd`, `order`, `brand`, `last-digits` and `OrderHash`. `crd` is the card token and only has a value when `code = 1`; store it with the customer email. Tilopay generates `order`, not the merchant.
