The new Search Ads 360 Reporting API is now available. Join the searchads-api-announcements Google group to stay up to date on upcoming enhancements and releases.

Report Streaming

There are two methods for retrieving entities and reporting data with the Search Ads 360 Reporting API.

This guide primarily focuses on streaming data from SearchAds360Service. Here are high-level distinctions for the two data retrieval methods:

	SearchAds360Service.SearchStream	SearchAds360Service.Search
Suitable for production code	Yes	Yes
Service	`SearchAds360Service`	`SearchAds360Service`
Scenario	Fetching objects and reports	Fetching objects and reports
Response	Stream of `SearchAds360Row` objects	Pages of `SearchAds360Row` objects
Response's fields	Only those specified in the query	Only those specified in the query
Daily limits	See API limits and quotas.	See API limits and quotas.

SearchStream versus Search

While Search can send multiple paginated requests to download the entire report, SearchStream sends a single request and initiates a persistent connection with the Search Ads 360 Reporting API regardless of report size.

For SearchStream, data packets start to download immediately with the entire result cached in a data buffer. Your code can start reading the buffered data without having to wait for the entire stream to finish.

By eliminating the round-trip network time required to request each individual page of a Search response, depending on your app, SearchStream can offer improved performance over paging, especially for bigger reports.

Example

Take a report that consists of 100,000 rows for example. The following table breaks down the accounting differences between the two methods.

	SearchStream	Search
Page size	Not Applicable	10,000 rows per page
Number of API requests	1 request	10 requests
Number of API responses	1 continuous stream	10 responses

Performance factors

In general, we recommend SearchStream over Search for the following reasons.

For single page reports (under 10,000 rows): No significant performance differences between the two methods.
For multiple page reports: SearchStream is typically faster since multiple roundtrips are avoided and reading/writing from disk cache is less of a factor.

Rate limits

Daily limits for both methods adhere to the standard API limits and quotas. A single query or report is counted as one operation regardless of the result being paged or streamed.
