Could not add bearer token in swagger docs

Question

I need to add bearer token in each API which has documented in swagger editor. But as per my code its not working as expected. I am explaining my code below.

swagger: "2.0"
info:
  description: "This is a sample API documentation of DCI project."
  version: "1.0.0"
  title: "Swagger API docs for DCI"
  termsOfService: "http://swagger.io/terms/"
  contact:
    email: "apiteam@swagger.io"
  license:
    name: "Apache 2.0"
    url: "http://www.apache.org/licenses/LICENSE-2.0.html"
host: "**.**.**.**"
basePath: "/bpa/api/v1.0/workflow/process-definition/"
tags:
- name: "DCI"
  description: "API to start the workflow of DCI."
  externalDocs:
    description: "Find out more"
    url: "http://swagger.io"
schemes:
- "https"
- "http"
paths:
  /DCI_PORT_MGMT/start:
    post:
      tags:
      - "Port Allocation"
      summary: "Add a new port"
      description: ""
      operationId: "addPet"
      consumes:
      - "application/json"
      produces:
      - "application/json"
      parameters:
      - in: "body"
        name: "body"
        description: "Start the port allocation workflow."
        required: true
        schema:
          type: object
      responses:
        "405":
          description: "Invalid input"
      security:
      - petstore_auth:
        - "write:pets"
        - "read:pets"
securityDefinitions:
  Bearer:
    type: apiKey
    name: Authorization
    in: header
externalDocs:
  description: "Find out more about Swagger"
  url: "http://swagger.io"

Here I need to add bearer token in header of each API. as per my code when I am executing the API its not asking to add any token . If somebody can help me it will be great help.

According to swagger docs and other answers you just need to have the security definition then use it in one or more of the paths. For example

swagger: "2.0"
info:
  description: "This is a sample API documentation of DCI project."
  version: "1.0.0"
  title: "Swagger API docs for DCI"
  termsOfService: "http://swagger.io/terms/"
  contact:
    email: "apiteam@swagger.io"
  license:
    name: "Apache 2.0"
    url: "http://www.apache.org/licenses/LICENSE-2.0.html"
host: "**.**.**.**"
basePath: "/bpa/api/v1.0/workflow/process-definition/"
tags:
- name: "DCI"
  description: "API to start the workflow of DCI."
  externalDocs:
    description: "Find out more"
    url: "http://swagger.io"
schemes:
- "https"
- "http"
paths:
  /DCI_PORT_MGMT/start:
    post:
      security:
        - Bearer: []
      tags:
      - "Port Allocation"
      summary: "Add a new port"
      description: ""
      operationId: "addPet"
      consumes:
      - "application/json"
      produces:
      - "application/json"
      parameters:
      - in: "body"
        name: "body"
        description: "Start the port allocation workflow."
        required: true
        schema:
          type: object
      responses:
        "405":
          description: "Invalid input"
securityDefinitions:
  Bearer:
    type: apiKey
    name: Authorization
    in: header
externalDocs:
  description: "Find out more about Swagger"
  url: "http://swagger.io"

If you test in swagger editor there is a authorize button (top right) that should allow you to enter credentials for this header. You can test the request/ execute it and you will see that a authorization header will be added.
