 As opposed to _dynamic_ links (i.e. links provided **in** the response payload), the OAS linking mechanism does not require that link information be provided in a specific response format at runtime.

 <a name="linkOperationId"></a>operationId  | `string` | the name of an _existing_, resolvable OAS operation, as defined with a unique `operationId`.  This field is mutually exclusive with the `operationRef` field.  Relative `operationRef` values MAY be used to locate an existing [Operation Object](#operationObject) in the OAS.
