How to replace "bearer" in Bearer Authentication with "idtoken"

[tayalaru14]

My project expects Authorization token with "idtoken" instead of "bearer". How should I implement it in open API: 3.0.1 ? Couldn't find anything in the documentation.

1. Authorization: idtoken <token>

The Authorization header with a custom value prefix can be defined as an API key. The prefix (in this case - idtoken) needs to be provided as part of the token value.

components:
  securitySchemes:
    IdToken:
      type: apiKey
      in: header
      name: Authorization
      description: Specify the token value with the `idtoken` prefix, e.g. "idtoken MYTOKEN".

security:
  - IdToken: []
