# Card tokenization request

This section explains how D1 handles a **Tokenization** request initiated by a **token requestor** (for example, **xPay Wallets**) and how to interpret the decision returned to the payment network **TSP** (for example, **MDES** or **VTS**).

{% hint style="info" %}
**Terminology in the D1 API**

In the **D1 API**, an **End User** is referred to as a `consumer` (for example, `consumerId`).
{% endhint %}

### Next steps

* Understand what happens after the decision: [Processing the response](/tokenization/implement-tokenization/card-tokenization-request/processing-the-response.md)
