Page Summary
-
The Merchant API is the new version of the Content API for Shopping and represents the future of the platform.
-
Merchant Center Query Language supports pagination to handle large result sets using
page_sizeandpage_tokenparameters. -
The
page_sizeparameter controls the maximum number of rows returned per request, defaulting to 1000. -
To retrieve subsequent pages of data, use the
next_page_tokenfrom the previous response as thepage_tokenin the next request. -
The
next_page_tokenwill not be included in the response containing the final batch of rows.
In order to handle result sets containing a large number of rows, Merchant
Center Query Language supports pagination. Two parameters are available to
control pagination in the reports.search
request
body
: page_size
and page_token
, in addition to one output field in the response
body
: next_page_token
.
The page_size
parameter specifies the maximum number of rows to retrieve in a
single request. If unspecified, it is automatically set to the maximum page size
of 1000 rows.
The page_token
parameter specifies the token of the page to return. If
unspecified, the first page is returned. To retrieve a subsequent page, the
value received as the next_page_token
from the previous reports.search
call
should be provided as a page_token
. When a page_token
is provided, all other
parameters in the call should match the previous call that returned the page_token
to avoid unexpected behavior.
Example:
SELECT
segments
.
offer_id
,
metrics
.
impressions
,
metrics
.
clicks
,
metrics
.
ctr
FROM
MerchantPerformanceView
WHERE
segments
.
date
BETWEEN
'2021-12-01'
AND
'2021-12-31'
For this query, assume the account contains 100,000 offer_ids
and the page_size
is set to 200. The result set will then contain 200 ReportRow
objects in the first response, along with a next_page_token
.
To retrieve the next 200 rows, send the request again with the same page size,
but update the request's page_token
to the previous response's next_page_token
.
Here is a response body example (the first five results plus the next_page_token
):
