Set TTL for API Gateway in Swagger - amazon-web-services

Question

I'm using cloudformation, and have enabled caching like this:
Type: AWS::ApiGateway::Stage
Properties:
CacheClusterEnabled: true
CacheClusterSize: 0.5
My methods are taken from swagger. Here's my swagger file for GET
/v1/myPath/{id}:
get:
tags:
- Books
operationId: getBook
parameters:
- name: id
in: path
description: The ID of the book to retrieve
type: integer
format: int32
required: true
- name: custom-header
in: header
type: string
responses:
'200':
x-amazon-apigateway-integration:
type: aws_proxy
httpMethod: POST
uri: arn:aws:apigateway:us-west-1:lambda:path...
passthroughBehavior: when_no_match
requestParameters:
integration.request.header.custom-header: method.request.header.custom-header
cacheKeyParameters:
- method.request.header.custom-header
How can I set the caching TTL for my GET request in my swagger.yaml? I can't seem to find documentation for this.

Way to add headers to cloudformation,
ResponseParameters
Response parameters that API Gateway sends to the client that called a method. Specify response parameters as key-value pairs (string-to-Boolean maps), with a destination as the key and a Boolean as the value. Specify the destination using the following pattern: method.response.header.name, where the name is a valid, unique header name. The Boolean specifies whether a parameter is required.
Required: No
Type: Mapping of key-value pairs
