webAclId

The ID of the WAF web ACL that you want to list the associated distributions. If you specify "null" for the ID, the request returns a list of the distributions that aren't associated with a web ACL.

For WAFV2, this is the ARN of the web ACL, such as arn:aws:wafv2:us-east-1:123456789012:global/webacl/ExampleWebACL/a1b2c3d4-5678-90ab-cdef-EXAMPLE11111.

For WAF Classic, this is the ID of the web ACL, such as a1b2c3d4-5678-90ab-cdef-EXAMPLE11111.
