Either/or required but not both

[marcus-maws]

Hi,

Is there any way in swagger definitions to specify that either one parameter or another is required, but not both?

e.g. firstname OR fullname is required, but not both

Thanks.

As of Swagger 2.0 it's not possible. What you can do is defining this logic in your 400 response.

swagger: '2.0'

      parameters:
        - name: firstName
          in: query
          description: First Nam
          type: string
        - name: fullName
          in: query
          description: description
          type: string
      responses:
        400:
          description: |

            You have to specifiy either `firstName` or `fullName` parameter.

Thanks. I was thinking of specifying it in the summary possibly in addition to your suggestion with the response.
