WSO2 API Manager is a complete solution for publishing APIs, creating and managing a developer community and for routing API traffic in a scalable manner. It leverages the integration, security and governance components from the WSO2 Enterprise Service Bus, WSO2 Identity Server, and WSO2 Governance Registry. In addition, as it is powered by the WSO2 Business Activity Monitor,
The API manager comprises the following components:
- API Gateway : Secures, protects, manages, and scales API calls. It is a simple API proxy that intercepts API requests and applies policies such as throttling and security checks. It is also instrumental in gathering API usage statistics.
- API Key Manager : Handles all security and key-related operations. API gateway connects with the key manager to check the validity of OAuth tokens when APIs are invoked . Key Manager also provides a token API to generate Oauth tokens that can be accessed via the Gateway.
- API Publisher : Enables API providers to publish APIs, share documentation, provision API keys, and gather feedback on API features, quality and usage.
- API Store : Enables API consumers to self register, discover API functionality, subscribe to APIs, evaluate them and interact with API publishers.
