# ServiceM8

> How to point a Link at a ServiceM8 online booking form, and the two limits that decide where this works.

Get the link from **Settings → Online Booking**, or from **Settings → Self-Serve Online Bookings**
if you have several forms. ServiceM8 hosts the form, so the link works for anyone — no account, no
app.

A tag on a hot water system, a switchboard or a site sign that books a service call is about as
direct as this gets.

## Two limits worth knowing before you produce anything

**There is no per-asset URL.** You point at a *booking form*, not at a record. So the useful split
is one form per service type — and that means the Destination varies by what the tag is on, not by
which unit it is. There is nothing per-Item to bind.

**SMS booking links are single-use.** ServiceM8 can text a customer a link to pick a time for an
existing job, and that link is tied to that job and that booking. It is not something to print. If
one ends up on a tag it will work once and then be wrong forever.
