# WAF Auto Task
> Solve Cloudflare WAF challenges
### Data
The URL of the page where the WAF challenge is located.
**Example:** `https://mune.rs/`
URL must include a path. For example, `https://mune.rs` is invalid—use `https://mune.rs/` instead.
The `User-Agent` we must use for the requests.\
Defaults to: `Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/144.0.0.0 Safari/537.36`
We support:
* Chrome (Windows, macOS, Linux, iOS & Android)
* Firefox (Windows, macOS, Linux, iOS & Android)
* Safari (macOS, iOS) // *Tested only on Safari 26*
The HTML body of the challenge you've encountered.\
If this is not sent, API will automatically try to retrieve the challenge from the URL.
The response you send us must have the header `Cf-Mitigated: challenge`.
If you provide this field, you must also provide the same User-Agent used for the request, and the TLS fingerprint must match that User-Agent.\
Otherwise, you will usually receive a `challenge triggered reload` error.
Proxy to use for solving the challenge.
**Format:** `://[username:password@]host[:port]`
**Example:** `http://user:pass@192.168.1.1:8080`
### Data Example
```json theme={null}
{
"url": "https://mune.rs/",
"html": "...", // optional
"proxy": "http://user:pass@192.168.1.1:8080"
}
```

### Solution Parameters
The WAF clearance cookie value.
**Cookie name:** `cf_clearance`
An optional Cloudflare bot management cookie value.
**Cookie name:** `__cf_bm`
HTTP headers used during the solve process. You must use these exact headers for your subsequent requests.
**Includes:** `user-agent`, `sec-ch-ua`, `sec-ch-ua-mobile`, `sec-ch-ua-platform`
Response from the URL you sent with solved cookies.
**Example:**
```json theme={null}
{
"status_code": 200,
"url": "current_url", // URL after redirects
"headers": { },
"base64_body": "..."
}
```
### Solution Example
```json theme={null}
{
"clearance": "abc123...",
"cf_bm": "xyz789...",
"headers": {
"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/137.0.0.0 Safari/537.36",
"sec-ch-ua": "\"Google Chrome\";v=\"137\", \"Chromium\";v=\"137\", \"Not/A)Brand\";v=\"24\"",
"sec-ch-ua-mobile": "?0",
"sec-ch-ua-platform": "\"Windows\""
},
"response": {
"status_code": 200,
"headers": {
"content-type": "text/html;charset=utf-8"
},
"base64_body": "...",
"url": "https:/mune.rs/"
}
}
```
***
Using a different IP from the one you used to solve will invalidate the clearance.
Always use the exact headers returned in the solution. Mismatched headers (especially `user-agent`) will invalidate the clearance.
