Make sure Cloudflare not block my frequent call

I going to add a payment call back for this URL and some hardware device will keep calling this URL also. how can I make sure Cloudflare will not block this frequent call? From the same Ip sometime.
thank you

To ensure Cloudflare doesn’t block frequent calls to your URL from the same IP, you can create a Firewall Rule that allows traffic from the specific IP addresses. Here’s how to do it:

  1. Log in to your Cloudflare account and select the domain you want to configure.
  2. Click on the “Firewall” tab in the menu.
  3. Navigate to the “Firewall Rules” section and click “Create a Firewall rule.”
  4. Give your rule a name, for example, “Allow Payment Callbacks.”
  5. Configure the rule with the following settings:
    - Field: IP Address
    - Operator: Equals
    - Value: Enter the specific IP address that should be allowed
  6. Under “Then,” select “Allow” as the action.
  7. Click “Deploy” to save and activate the rule.

You want to limit to a specific URL to allow, then you can add that to the rule as well

something like this? because all my hardware don have fix ip.
