How to make Dynamic Search Ads via curl request

[f s]

Hello, Google Ads API Team.

I'd like to create the Dynamic Search Ads via curl, so I post the following JSON to: https://googleads.googleapis.com/v1/customers/5838476xxx/campaigns:mutate

{
      'operations': {
        'create': {
          'name': 'New campaign',
          'advertising_channel_type': 'SEARCH',
          'status': 'PAUSED',
          'dynamic_search_ads_setting': {
            'domain_name': 'www.foo.com',
            'language_code': 'ja',
            'use_supplied_urls_only': true
          },
          'campaign_budget': 'customers/5838476xxx/campaignBudgets/2113622xxx',
          'start_date': '20190701',
          'end_date': '20190801',
          'manual_cpc': {
            'enhanced_cpc_enabled': false
          }
        }
      }
    }

But, I receive the following response:

{
  "error": {
    "status": "INVALID_ARGUMENT",
    "message": "Request contains an invalid argument.",
    "code": 400,
    "details": [
      {
        "errors": [
          {
            "errorCode": {
              "settingError": "DYNAMIC_SEARCH_ADS_SETTING_AT_LEAST_ONE_FEED_ID_MUST_BE_PRESENT"
            },
            "message": "At least one feed id should be present.",
            "trigger": {
              "stringValue": ""
            },
            "location": {
              "fieldPathElements": [
                {
                  "index": "0",
                  "fieldName": "operations"
                },
                {
                  "fieldName": "create"
                },
                {
                  "fieldName": "dynamic_search_ads_setting"
                }
              ]
            }
          }
        ],
        "@type": "type.googleapis.com/google.ads.googleads.v1.errors.GoogleAdsFailure"
      }
    ]
  }
}

What is feed id? How should I make it? Is that another request? Then, How should I do after creating a campaign?

Could you give me some hints?

Thanks.

Thank you, Bharani

I found the mistakes and succeeded, but I'm concerned. Just in case, I'll attach a successful pattern and a failed pattern via Node.js.

In a campaign request, if I put

  

'use_supplied_urls_only': true

I get an error, otherwise I will succeed.

Thank you for your help.
