White list IP addresses that Tyk Cloud uses


We would like to whitelist the IP addresses that Tyk Cloud uses when communicating with our proxied backend services. Is there a list of these published somewhere?



Hi Ryan,

Our cloud infrastructure autoscales, so the IP addresses are always changing. This means we can’t specify a fixed IP block.

The best way to ensure traffic is sourced from our cloud is to inject a secret header into all outbound requests using our global header injector in the API designer.

Many thanks,



Thanks for the quick reply. That should work for us. Thanks!
