Usage limits

The zero-touch enrollment APIs have a default limit of 1000 queries per
100 seconds for each user. In the reseller API, a user is the shared service
account. In the customer API, a user is
the authenticated IT admin.
Change usage limits
To view or change usage limits for your project, or to request an increase to
your quota, do the following:
- If you don't already have a billing account
for your project, then create one.
- Visit the Enabled APIs page of the
API library in the API Console, and select an API from the
list.
- To view and change quota-related settings, select Quotas. To view
usage statistics, select Usage.
Help staying under the limits
Use the asynchronous versions of the reseller API's Device methods to help
reduce the number of requests. These methods allow batch processing of many
devices in one request, while the synchronous methods process one device for
each API request.
To learn how to process many items in one API request, read Long-running batch
operations.
