The following example shows you how to list policies in your organization using Python.

Quota

For each Google Cloud project, Cloud Identity Policy API supports 1 query per second (QPS). For each customer, Cloud Identity Policy API supports 1 QPS in total, even if the customer creates multiple Google Cloud projects.

Quota increase is not supported.
