Configuring rules define conditions based on which it is possible to determine whether a policy has to be executed or not at runtime.

For example, an XML to JSON policy can be applied only if the Accept Header is set as application/json.

The Add/Edit Rule button at the lower-right part of each Policy Configuration page allows the API author to add additional rules to a policy before a message is passed to a policy.

A sample snapshot of the Monetization Limit Check Policy Configuration page is provided below.
