Not receiving order updates on post back url

I have setup 2 developer apps for testing the apis. I tried on local environment with cloudflare redirecting to localhost. And this is working fine. But when I deploy the same on AWS with our domain name as the post back url, we are not receiving any updates. How can we fix this issue?

Hi @dsouzaedison
It seems our firewalls are blocking your URL for security reasons. Please share your postback URL so we can check with our security team to have it whitelisted.

Thanks!

Hi, checked placing orders today. Still postback is not working. It’s been a week since I raised this issue. Still no resolution. Don’t see a point in offering free APIs that are not usable for building trading tools. Please let me know if it’s not possible. I will at least explore other broker APIs rather than wasting time waiting. Thanks. @Upstox
