# NuData

{% hint style="info" %}
Check our example bundles in order to validate your implementation against our validate ones, with correct headers order, TLS and flow from our [**Github repo**](https://takionapi.tech/examples)

## **What is NuData?**

NuData is a security service that protects sensitive actions such as logins and payments, commonly found on platforms like Ticketmaster and Kohl's. It check user actions to detect fraudulent activity. 

### Detecting a NuData site <a href="#detecting-a-castle-site" id="detecting-a-castle-site"></a>

Protected websites usually expect a parameter, often named **`nds-pmd`**, though the name may vary.

In other cases it may be called as **`x-src-nudetect-widgetdata`**, like for the **`stc.mastercard.com`** website.

{% hint style="warning" %}
NuData scores logins, checkouts, and payments. It is a fraud gate, not a scraping wall. We take on these targets case by case. [Contact us first](https://takionapi.tech/contact) so we can confirm we can clear your specific flow before you build against it.

## Some websites using Datadome <a href="#some-websites-using-it" id="some-websites-using-it"></a>

Most of the tickets websites are using Incapsula to protect their website. Here are some examples of websites using Incapsula and the cookies/challenge they require:

| Website                                                                                                                     |
| --------------------------------------------------------------------------------------------------------------------------- |
| [ticketmaster.com](https://www.ticketmaster.com/) / [ticketmaster.sg](https://www.ticketmaster.sg/) (and other sub domains) |
| [kohls.com](https://www.kohls.com/)                                                                                         |
| [Mastercard](https://src.mastercard.com/)                                                                                   |
| ...                                                                                                                         |
