Quotas and Limits
Stay organized with collections
Save and categorize content based on your preferences.
The CSS API imposes quotas and hard limitations on some
features. The quotas and limits shown in the following table are provided
solely to assist you in
developing applications that use the CSS API. All quotas and
limits are subject to elimination, reduction, or change at any time, without
notice.
Check your quota usage
You can check your current quota usage using the
accounts.quotas.list
method. This method lets you retrieve the current quota usage for your account.
See this sample
to learn how to perform this quota retrieval.
Quota policy
Don't update your products if they are unchanged. If you need to send updates to
keep a product from expiring, doing so once a week is enough.
Method call quotas
The following limits are the default method call quotas for CSS Center
accounts.
- Users exceeding the per minute quota receive
quota/request_rate_too_high errors.
- Users exceeding the per day quota receive
quota/daily_limit_exceeded
errors.
Here are some things to keep in mind:
- The quotas here are per-method. For example, the
get method has a separate
quota of calls from the update method, though the size of those quotas is
the same.
- Calls count against the quota of the affected account. For product related
operations this will be the CSS Domain account, for account list operation
it depends on the account the list is called on.
Here are the default limits:
