Enable SSO Auth Fallback Using REST API

[Reab]

Hi, 

I've been trying to enable authentication fallback using curl as mentioned Bypass SAML auth

However, PUT request doesn't work. I am getting "405 Method not allowed" I checked the REST API documentation I couldn't find anything related to the authconfig endpoint.

I was able to enable it through the database directly but I want to do it through the API instead. However, the flag is different in the database 

latest version: 

 com.atlassian.plugins.authentication.sso.config.enable-authentication-fallback

as opposed to previously:

com.atlassian.plugins.authentication.samlconfig.allow-saml-override'

The response from the GET request to this <BASE_URL>/rest/authconfig/1.0/sso is:

{    
"show-login-form": false,    
"enable-authentication-fallback": false,    
"show-login-form-for-jsm": true,    "last-updated": "
}

How can enable it through the REST API?

Solved - it should be a PATCH request
