# Use UniTokens

Use the **placeOrder** method to create an order using products defined in your Control Panel and collect the payment using a **previously issued UniToken** instead of full card details.

A UniToken represents a card that has already been used successfully by a customer. Pass its ID in **PaymentDetails.UniToken** with **PaymentDetails.Type** set to **UNITOKEN**. If the order is instead authorized with raw card details and the card matches an existing UniToken for the same customer (same first 4 and last 4 digits, on the same **CustomerReference / ExternalCustomerReference**), the system updates that existing UniToken with the new order reference rather than creating a new one.

Use **listUniTokens** to retrieve the tokens available for a customer before placing an order this way.

## 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.2checkout.com/json-rpc-api-reference/json-rpc-api-6.0/api-requests/place-orders-with-catalog-products/use-unitokens.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.
