AWS Single Sign-On endpoints and quotas
The following are the service endpoints and service quotas for this service.
To connect programmatically to an AWS service, you use an endpoint. In addition to
the standard
AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. For more
information,

limits, are the maximum number of service resources or operations for your AWS account.
For more information, see AWS service quotas.
