SSOfy provides two urls for logging a user out of the current session or all devices.
Assuming your website has a logout button, you should redirect the page to one of the following.
https://YOUR-LOGIN-DOMAIN/logout
https://YOUR-LOGIN-DOMAIN/logout-everywhere
You can direct the user to a certain URL when they log out. To accomplish this, add the parameter redirect_uri
to your url.
Example:
https://YOUR-LOGIN-DOMAIN/logout-everywhere?redirect_uri=https%3A%2F%2Fgoogle.com
After logging out, the user will be redirected to https://google.com
.
