API Overview

APIs provided by SFS include SFS APIs, SFS Turbo APIs, and native OpenStack APIs.

These APIs allow you to use all SFS functions.

The call frequency limit of SFS Capacity-Oriented APIs is 400 calls/minute. If you call a large number of APIs at a time, some APIs may fail to be called. You are advised to evenly arrange API calls.

Some SFS Capacity-Oriented APIs are the same as those provided by OpenStack Manila of the Mitaka version. For details about how to use them, visit the community:

https://docs.openstack.org/api-ref/shared-file-system/

For details about whether an SFS Capacity-Oriented API supports Enterprise Project, see API Permissions.
