Hi, Thank you for reaching out to the Google Ads API support team.
As per the CustomerNegativeCriterionOperation <https://developers.google.com/google-ads/api/rest/reference/rest/v18/CustomerNegativeCriterionOperation> you can only either create or remove. To create the negative keywords on account level, kindly follow the below steps: - You need to verify whether the shared set are created in your account by using the below query. "query":"SELECT shared_set.id, shared_set.member_count, shared_set.name, shared_set.reference_count, shared_set.resource_name, shared_set.status, shared_set.type FROM shared_set WHERE shared_set.type= 'ACCOUNT_LEVEL_NEGATIVE_KEYWORDS' AND shared_set.status='ENABLED'If it's already created you can use the shared set resource name. - If not, you need to create a shared set using the Method: customers.sharedSets.mutate <https://developers.google.com/google-ads/api/rest/reference/rest/v18/customers.sharedSets/mutate> request. *Sample Request Body:====================*POST https://googleads.googleapis.com/v19/customers/{customerId}/sharedSets:mutate?key=[YOUR_API_KEY] HTTP/1.1 developer-token: ********************** Authorization: Bearer [YOUR_ACCESS_TOKEN] Accept: application/json Content-Type: application/json { "operations": [ { "create": { "type": "ACCOUNT_LEVEL_NEGATIVE_KEYWORDS", "name": "Negative Keywords Testing1" } } ] } - Then you need to create a shared set criteria <https://developers.google.com/google-ads/api/rest/reference/rest/v18/SharedCriterion> by adding keyword and the earlier created shared set using the Method: customers.sharedCriteria.mutate <https://developers.google.com/google-ads/api/rest/reference/rest/v18/customers.sharedCriteria/mutate> request. *Sample Request body:=====================*POST https://googleads.googleapis.com/v19/customers/{customerId}/sharedCriteria:mutate?key=[YOUR_API_KEY] HTTP/1.1 developer-token: ********************** Authorization: Bearer [YOUR_ACCESS_TOKEN] Accept: application/json Content-Type: application/json { "operations": [ { "create": { "keyword": { "matchType": "EXACT", "text": "Testing keyword1" }, "sharedSet": "customers/3636059788/sharedSets/{sharedSetId}" } } ] } - After the above steps, you can use the CustomerNegativeCriterionService <https://developers.google.com/google-ads/api/reference/rpc/v18/CustomerNegativeCriterionService> to create the negative Keyword at the account and you need to provide the created shared set resource name as negative_keyword_list <https://developers.google.com/google-ads/api/reference/rpc/v18/CustomerNegativeCriterion#:~:text=Immutable.%20YouTube%20Channel.-,negative_keyword_list,-NegativeKeywordListInfo> value in the CustomerNegativeCriterion <https://developers.google.com/google-ads/api/reference/rpc/v18/CustomerNegativeCriterion> object under the MutateCustomerNegativeCriteriaRequest <https://developers.google.com/google-ads/api/reference/rpc/v18/MutateCustomerNegativeCriteriaRequest> . *Sample Request Body:===================*POST https://googleads.googleapis.com/v19/customers/3636059788/customerNegativeCriteria:mutate?key=[YOUR_API_KEY] HTTP/1.1 developer-token: ********************** Authorization: Bearer [YOUR_ACCESS_TOKEN] Accept: application/json Content-Type: application/json { "operations": [ { "create": { "negativeKeywordList": { "sharedSet": "customers/3636059788/sharedSets/{sharedSetId}" } } } ] } I hope this helps. Let me know how this goes on your end. Thanks and Regards, Google Ads API team.
