Define a single configuration rule using Terraform

The following example defines a single configuration rule for a zone using Terraform. The rule disables Email Obfuscation and Browser Integrity Check for API requests.

# Disable a couple of Cloudflare settings for API requests
resource "cloudflare_ruleset" "http_config_rules_example" {
  zone_id     = "<ZONE_ID>"
  name        = "Config rules ruleset"
  description = "Set configuration rules for incoming requests"
  kind        = "zone"
  phase       = "http_config_settings"


  rules {
    ref         = "disable_obfuscation_bic"
    description = "Disable email obfuscation and BIC for API requests"
    expression  = "(http.request.uri.path matches \"^/api/\")"
    action      = "set_config"
    action_parameters {
      email_obfuscation = false
      bic               = false
    }
  }
}

Use the ref field to get stable rule IDs across updates when using Terraform. Adding this field prevents Terraform from recreating the rule on changes. For more information, refer to Troubleshooting in the Terraform documentation.
