The April 2025 release of API Center includes the following new features and enhancements.
Real-time monitoring of APIs
You can gain real-time visibility into API health, including response times, latency, errors, and traffic. Additionally, you can access detailed analytics on API usage patterns, user behavior, and performance trends over time. You can use this data to optimize API operations, identify bottlenecks, and ensure compliance effectively.
API Center now provides various visual charts to help you.
For more information, see Monitor APIs.
Enhanced OAuth 2.0 support
You can now assign multiple managed APIs and managed API groups to a single OAuth 2.0 client. This improvement enhances API security and management by eliminating the need for multiple OAuth 2.0 clients. You can create a single OAuth 2.0 client to grant access to specific API sets, simplifying authorization control.
With this enhancement, disabling or deleting an OAuth 2.0 client will immediately invalidate its authorization token, preventing API access and enhancing security.
For more information, see API Policies.
Import of Application Integration processes to API Center
You can import all the Application Integration processes to API Center. The processes on the Service Name corresponds to the API Name and the Source Name corresponds to the Name in Application Integration.
This import capability helps you easily transition the REST APIs of published Application Integration processes into API Center. You can easily design, publish, and create managed APIs in API Center.
For more information, see REST API Assets.
Multibyte character support
You can use multibyte characters, including Japanese characters for the following API Center fields:
•Operation name
•API name
•Published API name
•Managed API name
•Policy name
•OAuth client 2.0
•Context
•API group name
•Managed API group name
•Custom API name
•Projects
•Application Integration process
For more information, see Manage APIs.
Date and Date Time data type support
When you define the request and response body of an API operation, you can select the Date and Date Time data types. You can also create an array type of the Date and Date Time data types.
Ability to edit operation policies in API groups
You can edit policies that are in created and inactive states of a Managed API group. Editing such policies enables you to reuse API groups with the same operations while applying different policies and context names.
You can reuse the same operation in multiple APIs with an API group but assign different policies and context names to the operations
You can also attach different policies to different operations when creating active managed API groups and hence ensures that you can reuse Published APIs directly from the API Console.
For more information, see Manage APIs.
API-level rate limit policy at operation level for API groups
If you associate an API-level rate limit policy with an API, but do not assign policies to individual API operations, the API-level rate limit policy is automatically applied to the operations when you add the published API operation to an API group. The active managed API groups will also enforce the applied rate limit.
This enhancement does not apply to the existing operations you previously added to a managed API group.
For more information, see Manage APIs.
Support for octet-stream content type
API Center now stores API responses that contain content types such as multipart/form-data and application/octet-stream. These new content types apply only when you include the file datatype in the request and response body fields during REST API creation.
Previously, API Center stored only application/json and XML content types.
For more information, see REST API Assets.
Array data type support in path and query parameters of an API operation
When you define the path and query parameters of an API operation, you can select the array type of the primitive data types. You can pass multiple values in the CSV format as default values for query parameters.
