New features¶
Egress API Management Capability with support for LLM/AI
This release of API Manager introduces the capability to integrate AI services and large language models (LLMs) with APIs. It offers token-based rate limits and flexible business plans, making it simpler to manage. You also get detailed analytics on token usage, request counts, and performance, helping you make smart business decisions around AI models and vendors. With full API lifecycle management, you have complete control over your AI APIs. Plus, the optimized API gateways are designed to handle AI services efficiently, boosting overall performance.
WSO2 Identity Server 7.0 Authorization Server Support
Integration with WSO2 Identity Server 7.x as an authorization server (key manager) is now supported, providing a unified key management solution for your API management requirements.
Support for Consuming APIs without Subscriptions
API Manager now has the capability to disable the subscription requirement for API consumption. This simplifies the user experience by allowing users to avoid subscription approval and application creation processes.
API Microgateway / Immutable Gateway Support with APIM 4.x
API Manager 4.4.0 and other members of the 4.x family can now be seamlessly integrated with the WSO2 Microgateway 3.2.0 allowing users to choose the most suitable gateway solution for their needs.
Dynamic API Flow Orchestration Support
This feature lets developers easily manage messages, connect multiple services, and gather responses right within the API Gateway. With Synapse sequences as endpoints, you can route requests, add custom business logic, and orchestrate multiple services seamlessly, all without changing your backend APIs. It’s a straightforward way to handle complex API workflows and integrations.
Enhanced Security with Client-Side mTLS Authentication
This feature boosts security with customized mTLS settings tailored to different environments, ensuring stronger protection. It also supports compliance by allowing environment-specific security configurations to meet various regulatory requirements. API consumers benefit from the flexibility to use different MTLS settings for production and sandbox environments without causing conflicts
Business Plan Updates for Existing Subscriptions
This approach offers flexibility to the users by allowing changes to business plans through API calls without requiring customers to unsubscribe and resubscribe.
Application Level Throttle Policy Reset Support
The latest version of API Manager introduces the capability to reset the Application level rate limiting policies once the throttling limit has been exceeded. With this, you no longer have to wait until the next access time if your API got throttled due to request spikes or unintended requests.
Subscription Approval Support from API Publisher Portal
The latest version of API Manager allows API product managers more control by letting them directly manage and approve subscription requests
Audience Validation Support for JWTs
This feature improves the API security by introducing an extra level of validation to the JWTs. This approach is particularly useful when you need to restrict the API access to a particular audience when APIs are shared among multiple clients or services.
Enhanced Content Search Support
The latest version of API Manager expands its content search capabilities by allowing the users to search within the OpenAPI/Swagger, GraphQL schema, AsyncAPI, and WSDL definitions of the APIs.
Multi DC Replication Support for PostgreSQL
API Manager has database replication support with Oracle and SQL Server. With the introduction of support to PostgreSQL in the latest version, users have more options to deploy API Manager in multiple data centers with database replication.
Filtering Support for Denylist Throttling Policies
This feature allows users to filter denylist throttling policies through the REST APIs.
