Tags are words or phrases that act as keywords for categorizing, identifying, and organizing APIs.

In API Gateway, you can assign tags to APIs, and their resources, methods, or operations. Tags help to logically catagorize APIs in different ways, for example, by usage, owner, consuming application, or other criteria. Tags are especially useful when there are multiple APIs of the same type - it enables to quickly identify a specific API based on the tag assigned to it. For example, you can assign the tag GET-Methods to specific GET methods in different REST APIs, and use it to search for the list of REST APIs with the GET-Methods tag in API Gateway.

You can use tagging, for example, to do the following:

You can assign one or more tags, remove a tag, and view the tags on the API details page. When a tagged API is published to API Portal, the published API in API Portal is tagged with the same tag defined in API Gateway.
