The April 2025 release of API Center includes the following changed behaviors.
Automated domain provisioning
API Center now automatically provisions a domain with the default domain as organization ID.com.
You can change the domain name on the Domain Settings tab on the Configuration page.
Previously, when you access API Center for the first time as an Admin or Deployer, you were prompted to select an API domain name and provision the domain. If the domain provisioning failed, you couldn't access API Center. For any other roles, you could access only limited functionalities of API Center for an unprovisioned domain.
For more information, see Introducing API Center.
Handle multiple HTTP codes
When you import an API definition with multiple response codes, you can view all the response codes in the Response tab of the operation panel. You can edit the responses.
Previously, you could see only one 200 OK response code.
Conflict resolution during import of API definition
When you import an API definition with same operations, API Center adds the imported assets without replacing the existing assets. API Center doesn't show conflicts during import, but validate the unique endpoint when you try publish the API.
Previously, you could not import an API definition that contained same operation name.
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 file datatype in the request and response body fields during REST API creation.
Previously, API Center stored only application/json and XML content types.
Array data type in path and query parameters of an API operation
When you define the parameters of an API operation, you can select the array type of the primitive data types in the path and query parameters. You can pass multiple values in CSV format as default values for query parameters.
Previously, you could select only the primitive data types of integer, string, number, and boolean.
