The Search Ads 360 Reporting API supports pagination of query results through the Search
method by specifying page_size
in your request. This will break up the result set of the query into multiple responses that each contains
up to page_size
objects. If page_size
is not specified, it is automatically set to the maximum page size of 10,000 rows.
For example, with the following query:
SELECT
ad_group.id,
ad_group_criterion.type,
ad_group_criterion.criterion_id,
ad_group_criterion.keyword.text,
ad_group_criterion.keyword.match_type
FROM ad_group_criterion
WHERE ad_group_criterion.type = KEYWORD
If your account contains 50,000 keywords and page_size
is set to 1,000
, the
result set will contain 1,000 SearchAdsRow
objects in the first response,
along with a next_page_token
. To retrieve the next one thousand rows, simply
send the request again with the same page size, but update the request's
page_token
to the response's next_page_token
. The value of page_size
in
the subsequent requests can be different each time.
Our client libraries handle paging automatically. You only have to iterate through the rows of the response. When all the rows in the current page have been returned, the client library will fetch a new page of rows automatically on your behalf until the entire data set has been retrieved. If using REST instead of gRPC, you must explicitly make a request for each new page.
Search Ads 360 Reporting API internally caches the entire data set, so subsequent requests are faster
than the first request. Depending on your use case, you can set page_size
to
any value between 1 and 10,000. In general, for faster overall performance, you
should use a larger page_size
due to fewer round trips in your responses.
