Cloudflare Blocking Rule Updates


When using the rules to webhook functionality my cloudflare hosting is blocking messages (requiring CAPTCHA). This is fixed by white listing the IP the request has come from, however I am getting different IPs posting the rules.

I need to whitelist all the potential IPs a rule can come from. Do you have a list of these available?


  • [ ] Self hosted with docker
  • [ ] Self hosted with IIS
  • [ ] Self hosted with other version
  • [X] Cloud version


I can probably provide you a list of IPs but in an cloud environment it could change over time. Can you post the IPs you see?

So the complete list is:
