    autoCreate: true                 # create queue if not exists
    apiVersion: '2012-11-05'
    host: localhost
    port: 9324
    https: false # default false
    region: eu-west-1
    accessKeyId: root
    secretAccessKey: root
    skipCacheInvalidation: false

custom:
  serverless-offline-sqs-external:
    autoCreate: true                 # create queue if not exists
    apiVersion: '2012-11-05'
    endpoint: 'http://localhost:9324'
    region: eu-west-1
    accessKeyId: root
    secretAccessKey: root
