Online booking: a public page for appointment scheduling

Kolio online booking is a public page on which customers pick a service, day and time among the free slots of your calendar and confirm the appointment with their details. It is written to the calendar with the source “Online booking”; the customer gets an email confirmation and a reminder. This chapter covers switching on, embedding, confirmations and protection.

What is Kolio online booking?

Kolio online booking is a public appointment scheduling page hosted at kolio.si/en/book/YOUR_KEY that you add to your website as a link, a frame or a script. The customer picks a service, day and time, enters name, email, phone and a note and consents to data processing; the appointment lands in the same calendar as appointments booked by the AI agent on the phone or in the website chat.

The page shows only free slots: it respects the opening hours of public locations, team member availability and every appointment already booked, whatever its source. It works in English and Slovenian — the Slovenian version is at /narocanje/YOUR_KEY or with the ?lang=sl parameter.

  • Where to set it up: Settings → Online booking — switch, page text, confirmation mode and embed codes.
  • What it needs: at least one service marked as publicly bookable and availability set up (Calendar and services).
  • Where the appointment goes: to the Calendar with the source Online booking; the customer's contact with consent to the CRM.

How do you switch on online booking?

You switch online booking on in Settings → Online booking; until the switch is on, the public page shows a notice that booking is not available, even if the code is already embedded on your site.

  1. Open the settings

    In the menu choose Settings → Online booking. Members with the nastavitve (settings) permission see the page.

    Settings → Online booking
  2. Switch on the public page

    Turn on the switch for the public page. On the first save Kolio creates the page's public key and shows the link and the embed codes.

  3. Enter the headline and intro

    Enter the Headline and Intro the customer sees above the form — in Slovenian and, if you will offer the page in English too, in English. Without English text the Slovenian text is shown.

  4. Choose phone and confirmation mode

    Decide whether the phone is required and whether appointments are confirmed automatically or by your team (the appointment waits as unconfirmed).

  5. Save and test

    Click Save, open the page link and make a test booking; then cancel the appointment in the calendar.

The page's logo and colour come from the account settings; the confirmation and reminder text from the templates.

Which services and slots appear on the page?

The booking page lists only services marked as publicly bookable in Calendar → Services; internal services (e.g. “internal meeting”) stay hidden. The location's opening hours, the availability of the service's staff and the service duration determine which times the page offers.

  • Locations: the page offers only public locations (checkboxes in Settings → Online booking → Locations online); with several locations the customer picks one first, with a single location it is shown in the summary and confirmation.
  • Location opening hours and staff: free slots are the intersection of the location's opening hours, closures and the availability of members who perform the service at that location; a service without staff has no slots.
  • Existing appointments: a time that is already taken — from a call, chat, the web, internally or via API — is not shown.
  • English name and description: the Name (EN) and Description (EN) fields on the service and location; without them the English page shows the Slovenian name.

How do you embed online booking on your site?

You embed online booking in three ways; all three codes are in Settings → Online booking and work without a plugin on any system that lets you add a link or HTML code.

1 · Link to the hosted page

https://kolio.si/en/book/YOUR_KEY
https://kolio.si/narocanje/YOUR_KEY
English and Slovenian version of the same page; the language can also be set with ?lang=en or ?lang=sl.

2 · Frame (iframe) on your subpage

<iframe src="https://kolio.si/embed/narocanje/YOUR_KEY?lang=en"
        title="Online booking" style="width:100%;min-height:720px;border:0"></iframe>
The visitor stays on your domain; the form runs in a frame from the Kolio server.

3 · The kolio-booking.js script

<!-- floating button that opens the form in a modal -->
<script src="https://kolio.si/kolio-booking.js" data-key="YOUR_KEY" data-mode="button" data-lang="en" data-label="Book now" defer></script>

<!-- form embedded where the tag stands -->
<script src="https://kolio.si/kolio-booking.js" data-key="YOUR_KEY" data-mode="inline" defer></script>
data-mode="button" adds a button in the corner of every page (label via data-label); data-mode="inline" (default) renders the form where the tag stands. data-lang="sl|en" sets the language, otherwise your page language applies.
Three ways to embed Kolio online booking
MethodWhen to choose itChange to the site's code
LinkA “Book now” button, email signature, Google Business profile, social media.None.
Frame (iframe)Your own “Booking” subpage on your domain.One iframe tag.
ScriptA button on every page (button) or the form in a specific section (inline).One script tag.

What does the customer receive after booking?

After booking, the customer receives an email from the booking_confirm template with the service, time, your details and a link on which they can reschedule or cancel the appointment themselves; the day before the appointment they receive a reminder. If your mailbox is set up (Email), both messages go out from your address.

  • Automatic confirmation: the appointment is confirmed at once and the confirmation goes to the customer the moment they book.
  • Team confirmation: the appointment is marked unconfirmed (amber) in the calendar; when your team confirms it, the customer receives the confirmation.
  • Reschedule and cancel: the link in the confirmation opens a page where the customer picks another free slot or cancels; the change is visible in the calendar immediately.
  • Text: edit the booking_confirm template and the reminder in Settings → Templates.

How does the calendar tell appointment sources apart?

The Kolio calendar marks every appointment with its source so your team sees where it came from: Call (AI agent on the phone), Website chat, Online booking (public page), Internal (entered by the team) and API (integration or MCP). All sources share the same staff, so double bookings are not possible.

Week view: appointment cards carry a source badge; unconfirmed appointments are amber.

How is the public page protected against abuse?

The public form is reachable by anyone, so Kolio checks every booking before writing it to the calendar. The protection works automatically and needs no configuration.

  • Hidden field (honeypot): a field the visitor never sees but bots fill in — such a booking is rejected.
  • Limit per IP address and email: too many attempts in a short time from the same address or with the same email are paused by Kolio (the form asks the visitor to try again later).
  • Slot re-check: at save time Kolio re-checks opening hours, availability and existing appointments; if the slot was taken in the meantime, the customer picks another.
  • Consent: without confirmed data processing no booking is possible; the consent is recorded on the contact in the CRM.
FAQ

Frequently asked questions

Can a customer book a slot that is already taken?

The Kolio online booking page shows only free slots from the calendar, respecting the location's opening hours and team availability, and re-checks the slot at save time. If someone else took it in the meantime, the customer is notified and picks another time.

How do I embed online booking on WordPress or Shopify?

Kolio online booking is a link, a frame or a plain script with no plugin: add the link as a menu button, or paste the iframe or script tag into the HTML field or the field for additional scripts your system provides. Copy the codes from Settings → Online booking.

Can my team confirm appointments before the customer gets a confirmation?

In Settings → Online booking turn off automatic confirmation: the appointment then waits in the Kolio calendar as unconfirmed (amber), and the customer receives the email confirmation once your team confirms it.

Is the booking page available in Slovenian too?

The Kolio online booking page is available in English and Slovenian: the Slovenian version is at /narocanje/<key> or with the ?lang=sl parameter. The headline and intro are entered in both languages in the settings, and the name and description per service.

Where do I see who booked an appointment online?

In the Kolio calendar every appointment from the public page has the source “Online booking”, and the appointment dialog shows the customer's name, email, phone and note. The contact with consent is in the CRM with the history of all conversations and appointments.

Which plan includes online booking?

Kolio online booking is included in the Growth and Custom plans and is fully available during the 7-day trial. On the Starter plan, Settings → Online booking shows only an upgrade card, and the public page and embeds with an existing key stop working after a downgrade to Starter until you upgrade again.
