An OpenAPI document needs to specify responses for all API operations. Each operation must have at least one response indicating successful handling of the request by the server. A response is defined by its HTTP status code and the data returned in the response body and/or headers
Add Method Response
Select the method you want to add the response to. Then select the non-global responses tab where you can either click the + button or New Response from the drop-down menu from the local toolbar.
A new response is added with a default content type. Input fields are being shown for the edition. Local link buttons are also shown when hovering over this new response.
Add Global Response
To add a global response, select the tab Global Responses then click the addition button (+) in the local (top-right) toolbar.
Delete a Response
To delete a response, select the response tab then click the delete button (the red X) from the local toolbar.
Use the response fields to update it. Hover over of the response to view other link buttons to change the response schema, delete the response content or edit the content schema example.
Add New Response Content Type
Select New Response Content Type from the local toolbar.
Update/Delete Response Content Type
A response may contain multiple content types. To delete a content type from a response, hover over it then click the link Delete content from that content local menu.
Update Response Content Type Schema
You can add a schema to the content type by clicking the red link "Add schema" at the bottom of the content type. Or click Change schema link from the local toolbar.
You can either select an existing schema:
Or create a new schema on the fly and use it in this content type. You can create an inline schema by letting the name field blank.
If you give the schema being created a name, it'll be also automatically added to the global components/schemas. It's then not an inline schema but referred to, by the content type.
Responses from an API can include custom headers to provide additional information on the result of an API call. For example, a rate-limited API may provide the rate limit status via response headers as follows:
Add Response Header
To add a new header, select a response then select New Header from the menu at the top right. A new header UI is shown. Give it in a name and eventually fill in other fields. Then give it a schema or content. To select a schema click the link Add schema... at the bottom of the header UI. You'll be prompted with a wizard to select an existing schema or create a new one. To use a content type with this header, click the link Add content... at the bottom of this header UI.
Delete Response Header
To delete a response header, click the Delete header link from that header local toolbar.
