简介：从2017年5月15日开始，Content API for Shopping将会引入QPS限制，具体数字会在QPS实施后发布在此文档中。

Starting on May 15, 2017, we will enforce new queries-per-second (QPS) limits on calls to the Content API for Shopping. This change will help with maintaining stability and uninterrupted access to all users of the API. Currently, almost all existing users already conform to the new QPS limits we will enforce, so unless you are directly contacted by us, you should not see any changes.

The new QPS limits will be in addition to the existing per-minute and per-day quotas on method calls. However, these limits will be enforced per Google API Console project, unlike the method call quotas which are enforced on individual Merchant Center accounts. Another difference is that the QPS limit will be for individual HTTP requests, not for individual method calls, so a single HTTP request to the custombatch method will count as a single call against the QPS limit. This is an additional reason to use custombatch methods if you plan on making many calls to a single service within a short time period. Once these limits are in force, they will be documented along with the other published limits for the Content API for Shopping.

If you have any questions or feedback about the QPS limits or other questions about the Content API for Shopping, please let us know on the forum.
