API Swagger SecurityDefinitions

is there any way to specify a SecurityDefinition like Api Key or Oauth in the API designer?

Swagger Example:

securityDefinitions:
store_auth:
type: oauth2
flow: accessCode
authorizationUrl: ‘https://xxxx.xxx.com/oauth/authorize
tokenUrl: ‘https://xxxx.xxx.com/oauth/token
scopes:
‘write:redeem’: Approve/Update redeem
‘read:clientFullName’: read client name
api_key:
type: apiKey
name: api_key
in: header
api_secret:
type: apiKey
name: api_secret
in: header

We are sorry that SecurityDefinition is not yet supported in Swagger generation.
It will be support in future release.
We will notify you when Swagger generation is enhanced to support SecurityDefinition.
