The Content API for Shopping now automatically increases your products and accounts quotas as your account grows.
Because your API quota now changes dynamically, we have removed the static chart from our published limits guide. To check your current daily quota and usage, and current per minute quota, you can call the quotas.list service.
The following errors are not API quota errors and can’t be resolved by automatic quota increases. They require you to request a quota increase.
Automatic quota only applies to the products and accounts services. If you need an increased API quota for any other service, or if you’re hitting your daily API quota for the products or accounts services or need a temporary increase for the accounts or products services, contact us with the following information:
Note that our general quota policy is you should not update your products more than twice per day, and that you should check your accounts and account statuses not more than once per day.
If you have any questions or concerns, please don't hesitate to contact us via the forum.
