# Reese84
Sites protected by **Incapsula** (now Imperva) often require solving the `reese84` sensor challenge before granting access. This page explains how to detect the challenge and solve it with our API. For the request fundamentals that apply throughout, see [TLS & Fingerprinting](/getting-started/tls-fingerprinting.md).
## Do you need to solve reese84?
If you are blocked by Incapsula, you typically receive a "Pardon Our Interruption" page:
> **Pardon Our Interruption** Your request was blocked as part of a security challenge. This usually happens when the site thinks your behaviour may resemble that of a bot.
A simplified version of the block page:
```html
```
## Find the reese84 endpoint
Inside the block page, look for a script tag injected by the site. It often looks like this:
```js
if (!isSpa) {
var scriptElement = document.createElement('script');
scriptElement.type = "text/javascript";
scriptElement.src = "/GEDIE-OF-MACBETH-king-Were-Throws-our-Chield-who/6913314970835659247?s=gLmE3ZfY";
scriptElement.async = true;
scriptElement.defer = true;
document.head.appendChild(scriptElement);
}
```
In this example, taken from `https://www.pokemoncenter.com`, the challenge endpoint is:
```
https://www.pokemoncenter.com/GEDIE-OF-MACBETH-king-Were-Throws-our-Chield-who/6913314970835659247?s=gLmE3ZfY
```
## Solve reese84 with our API
Submit the full challenge URL to our API - see the [API Reference](https://github.com/toman-tom/disasm.dev-docs/blob/master/incapsula/api-reference.md). We return a solution; submit that solution to the Incapsula endpoint and you receive a `token` in response. That `token` is the reese84 cookie - add it to your cookie jar.
