I want to define PaymentMethod
as below. Is oneOf supported in swagger.yaml?
PaymentMethod:
oneOf:
- $ref: '#/definitions/NewPaymentMethod'
- $ref: '#/definitions/ExistPaymentMethod'
The ExistPaymentMethod
will have just id, and cardNumber
where NewPaymentMethod
will have no id
, but all other details, e.g. cardNumber
, cardholderName
, cardholderAddress
etc.
oneOf
is supported in OpenAPI version 3 (openapi: 3.0.0
), but not in Swagger version 2 (swagger: '2.0'
).
PaymentMethod:
oneOf:
- $ref: '#/components/schemas/NewPaymentMethod'
- $ref: '#/components/schemas/ExistPaymentMethod'
