About this task

  • This task relates to configuring an OpenAPI 3.0 API definition. For details on how to configure an OpenAPI 2.0 API definition, see Editing an OpenAPI 2.0 API definition.

  • For details of current OpenAPI 3.0 support limitations, see OpenAPI 3.0 support in IBM® API Connect.

You can complete this task either by using the API Designer UI application, or by using the browser-based API Manager UI.

To make use of a response component, you must reference it from elsewhere in your API definition.

At any time, you can switch directly to the underlying OpenAPI YAML source by clicking the Source icon OpenAPI Source icon. To return to the design form, click the Form icon Form icon.


  1. Open the API for editing, as described in Editing an OpenAPI 3.0 API definition.
  2. Expand Components then, if there are already one or more response components defined, expand Responses.
  3. You can create a new response component, or edit any existing response component.
