Update Configuration (Version 1.0)

This article explains the legacy version of Rate Limiting 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.

Updates your entire rate limiting configuration.

Recommended Update Procedure:

The recommended procedure for fine-tuning a rate limiting configuration is outlined below.

Call the Get Configuration (Version 1.0) endpoint to retrieve the entire configuration.
Modify the response of the Get Configuration (Version 1.0) endpoint as needed.
Set the request body of the Update Configuration (Version 1.0) endpoint to the data updated in step 2.

Request

A request to update the rate limiting configuration is described below.
