Resolving DataDome 403 Errors
DataDome uses behavioral analysis and device fingerprinting to detect automated traffic. When requests fail verification, servers return 403 errors or serve deceptive block pages. MeshPrivacy generates valid datadome cookies by completing the behavioral verification process.
Error Codes
| Code | Meaning | Resolution |
|---|---|---|
| 403 | Access denied, challenge required | Generate valid datadome cookie via API |
| 200 | Deceptive block page (challenge HTML) | Detect and solve embedded challenge |
Note: DataDome may return 200 status with challenge HTML instead of 403. Check response content for dd= parameters.
Cookies & Detection

Interactive slider captcha challenge. Requires drag interaction to verify human behavior patterns.
Integration Example
// Submit DataDome task to MeshPrivacy
// Service variants: datadome-invisible, datadome-device-check, datadome-slider
const response = await fetch('https://api.meshprivacy.com/v1/tasks/submit', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'X-API-Key': API_KEY
},
body: JSON.stringify({
service: 'datadome-invisible', // or datadome-device-check, datadome-slider
url: 'https://target-site.com/',
proxy_config: 'http://user:pass@ip:port', // Your proxy
initial_cid: '', // Optional - existing datadome cookie if available
user_agent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36...'
})
});
const { task_id } = await response.json();
// Poll for result
const result = await fetch(`https://api.meshprivacy.com/v1/tasks/result/${task_id}`, {
headers: { 'X-API-Key': API_KEY }
});
const { cookies } = await result.json();

Check the response HTML for DataDome challenge indicators: dd= parameters, DataDome JavaScript includes, or challenge-specific HTML structure. A valid response will have your expected content.
DataDome cookies typically remain valid for approximately 10 minutes. For high-traffic applications, implement token refresh before expiration.
Yes, DataDome correlates cookies with IP addresses and behavioral patterns. MeshPrivacy tokens are designed to work with your IP, but rapid IP changes may trigger additional verification.
