To retrieve an SSO group called SalesGroup using the FortiAuthenticator REST API, the following issues need to be fixed in the API call:

The API version should be v2, not v1, as SSO groups are only supported in version 2 of the REST API.

The HTTP method should be GET, not POST, as GET is used to retrieve information from the server, while POST is used to create or update information on the server. Therefore, a correct API call would look like this: curl -X GET -H “Authorization: Bearer ” https://fac.example.com/api/v2/sso/groups/SalesGroup References: https://docs.fortinet.com/document/fortiauthenticator/6.4.1/rest-api-solution-guide/927310/introduction https://docs.fortinet.com/document/fortiauthenticator/6.4.1/rest-api-solution-guide/927311/sso-groups
