How to create API categories in WSO2 API Manager 3.1WSO2 API Manager is a fully open-source solution for end to end API management in the cloud and on-premise environments. It is a complete solution that allows API developers to design, publish, and manage the lifecycle of APIs. It hosts an application developer portal which helps in building and managing a developer community for our APIs. API Manager is now integrated with a variety of services and presents more features to developers and consumers for API management use-cases.

The latest version of WSO2 API Manager v 3.1.0 is equipped with many useful features and improvements such as – Integration with AWS Lambda, a recommendation system for API store by analyzing the behavior of the developer application, Graphical tryout Console for Developer Portal, API security Audit integration and an API categories feature to enable API providers to categorize their APIs and many more. For the purpose of this blog, we will focus on API categories feature.

In WSO2 API Manager 3.1.0, you can define and use API categories to group APIs belonging to the same category in terms of functionality / usage / teams, et cetera for improved user experience. First, you need to define API categories in the Admin portal, and they will be made available in the Publisher for assigning them to APIs as part of the design configuration.  Once the categorized API gets published to the Developer Portal, they appear as a clickable link to users, which makes it easy for consumers to consume APIs by checking the category of their interest.

Note: In the previous version of WSO2 API Manager 3.0.0, the grouping of APIs was a bit cumbersome using tag-wise groups. API tags had naming constraints where tags need to be defined with the suffix ‘-group’ in order for them to be treated as tag-wise groups in the developer portal, and tag-wise mode had to be enabled in order to display APIs in a grouped manner on the developer portal.

Below are steps to define the API category and associate API to categories.

Step 1: Add an API Category

Admins can add an API category by using the Admin Portal UI or the Admin REST API.

Sample payload

{ "name":"Sales", "description":"Sales Category" }
