The problem

When making API requests, you may receive an HTML error page instead of the expected JSON response:

​
Why this happens

This block is a platform security measure. The API has a firewall that monitors request origins and blocks traffic from unusual or suspicious locations. The firewall protects both the platform and integrators from attacks and malicious activity.

​
Security technologies

We use security services to protect the infrastructure:
  • Cloudfront: Amazon Web Services content delivery network.
  • AWS WAF: Amazon Web Services web application firewall.
These tools analyze traffic and block requests from locations that are not recognized as safe or that show suspicious patterns.

​
Accepted locations

Requests are allowed when they originate from locations considered safe, such as:
  • Brazil
  • United States
  • Portugal
  • Other locations considered safe

​
How to resolve it

If you are facing this issue, the solution is to change the request origin to one of the accepted locations above. You can do this by:
  • Using a server located in one of the accepted countries, such as Brazil, the United States, or Portugal.
  • Using a VPN with a server in one of the accepted countries.
  • Using cloud services, such as AWS, Google Cloud, or Azure, with servers in data centers in accepted countries.

​
Summary

  • The block happens when the request comes from a location that is not recognized as safe.
  • The response is an HTML error page instead of JSON.
  • The solution is to change the request origin to a server located in Brazil, the United States, Portugal, or another safe location.
  • It is not possible to request an exception or IP whitelist for this type of block.
