This article explains the legacy version of WAF that underwent end-of-life on June 30, 2021. Our new version of WAF expands upon all of the capabilities offered by WAF (Legacy) and Rate Limiting (Legacy) with a simplified and centralized setup. Please upgrade to the latest version of WAF at your earliest convenience.

WAF Essential cannot be configured via our APIs. However, you may leverage our APIs to retrieve WAF and Rate Limiting event log data.
