What’s changing? 
Last year, we introduced  query_resource_consumption metric as a way to measure how expensive a Google Ads API query is. However, this cost was not returned when the query results were empty.
Starting the week of August 4, 2025 , we will modify the behavior of both the Search SearchStream GoogleAdsService in all the API versions to return the query_resource_consumption metric and the field_mask field even when the query results are empty. The responses for empty query results will change as follows:
  
  Method Old response New response  
  
  
  Search 
  {    
    "fieldMask": "..."     
} 
{
    "fieldMask": "...",
    "query_resource_consumption": 123
} 
     
   
    
  SearchStream 
  [] 
{
    "fieldMask": "...",
    "queryResourceConsumption": 206
}
