FYI, its now possible to revert a snapshot via the REST API.
POST /vms/:id/actions/revert_snapshot
And the body of the endpoint:

{
  "snapshotId": <snapshot-id>
  "snapshotBefore": boolean (optional)
}

FYI, all endpoints are now documented in Swagger.

The REST API code is available here.

The revert snapshot action is not yet accessible via the REST API, but you can use it with xo-cli.

See
xo-cli vm.revert snapshot=<snapshot-id>

Can I see the API endpoints myself? Is the code open source?
https://github.com/vatesfr/xen-orchestra/blob/master/packages/xo-server/src/api/vm.mjs#L1088
Did I find the correct entry point?
Maybe I should use xo-cli to perform the revert operation? Or does the cli also access the API and can't provide more functionality?

Each month we migrate more and more endpoint to it (it's almost done).

But, for example, for VMS, there are the following actions:
curl -k -X GET -H "Content-Type: application/json" -b authenticationToken=<my-token-from-user-authentication-tokens> 'https://<xen-local>/rest/v0/vms/<vm_id>/actions'
[
"/rest/v0/vms/<vm_id>/actions/clean_reboot",
"/rest/v0/vms/<vm_id>/actions/clean_shutdown",
"/rest/v0/vms/<vm_id>/actions/hard_reboot",
"/rest/v0/vms/<vm_id>/actions/hard_shutdown",
"/rest/v0/vms/<vm_id>/actions/snapshot",
"/rest/v0/vms/<vm_id>/actions/start"
]
but in swagger you can see only one action - start
So, not everything available through the API is reflected in Swagger?Screenshot 2025-10-14 181918.png

Thanks.

Can I be sure that all API capabilities are reflected in Swagger?

So far, I've only found one method: creating a scheduled job, which can be launched via the API.
curl -k -X POST -b 'authenticationToken=<my-token-from-user-authentication-tokens>' 'https://<xen-local>/rest/v0/schedules/<schedule-id>/actions/run'
But that's a bit of a complicated process.

You should use the integrated Swagger doc. Directly from your browser, eg:
https://<xen-local>/rest/v0/docs/#/vms

You will see in green all the actions possible. Revert isn't implemented yet in the REST API AFAIK.
