SLO for Google Apps/GSuite

Hello Everyone,

Does anyone has configured Single Logout Out for GSuite? I couldn’t find any option with default G Suite App available in Okta marketplace. So I integrated G Suite with “Custom SAML App” mode. Now I established SSO and enabled “SAML Single Logout” and configured as below.

On Okta → Single logout URL: https://www.google.com/a/domain.com/acs
On Google → IDP Logout URL : https:/myorg.oktapreview.com/app/gsuite/exkedjkdkhsdWznv0h7/slo/saml

Now Signout initiation from Google gives me 403 ACCESS FORBIDDEN on Okta page for SLO URL. and If I tried to sign out from Okta, It is not logging out the google session.

Can someone help me if I am doing something wrong here?

Thanks.

Under the advanced settings for SAML app config you need to provide the parameters including SP cert for SLO:
