You can define policies to enforce security, access rules, and privacy for a specific managed API or custom API. You can also reduce redundant backend load by creating response caching policies for APIs.
For each API, you can configure the following policies:
•Rate limit policy. Controls the number of times API consumers can invoke the API during a designated time period, as defined by rate limit tiers.
•Response caching policy. Defines how long API Manager stores API responses in the cache.
•IP filtering policy. Designates the range of computer IP addresses that are allowed or that are denied permission to invoke the API.
•Privacy policy. Protects private information that is contained in API data.
