This is the persolog URL shortener behind go.persolog.online. Short links are created by persolog services and inside the persolog Online app — there is no sign-up or link creation on this page.
Following a short link redirects you to its target. If a link is unknown or has expired you'll see a short notice instead.
Integrating a persolog service? The API reference (creating links needs a Keycloak bearer token) is here: API documentation.
