+### Generate SSO login link
+If you're using SSO, you can use the above API to also generate login link for your users who aren't already logged in. Please make **sure** to include the "mode" parameter as "login" in the request body.
+
+```bash
+curl -XPOST https://shuffler.io/api/v1/orgs/{CURRENT_ORG_ID}/generate_sso_login_link -H "Authorization: Bearer APIKEY" -d '{"org_id": "ORG TO CHANGE TO", "sso":true, "mode": "login"}'
+```
+
+Similarly, you can generate a link to allow your user to be connected to your organization as well by using the same request body but removing the "mode" parameter.
+
+```bash
+curl -XPOST https://shuffler.io/api/v1/orgs/{CURRENT_ORG_ID}/generate_sso_login_link -H "Authorization: Bearer APIKEY" -d '{"org_id": "ORG TO CHANGE TO", "sso":true}'
+```
