FOR YOUR WEBSITE PERSON

Add calendar.fish to your site.

Four ways to take bookings, from zero code to one line of code. Everything below uses your business handle — the bit after calendar.fish/ that you picked at sign-up.

1 · Just a link 2 · Embedded widget 3 · Book button 4 · WhatsApp link

01

Just a link — no website needed

Your hosted booking page is live the moment you sign up. Put the link anywhere a link can go: Instagram bio, Facebook page, Google Business profile ("Booking link"), email signature, linktree.

https://calendar.fish/harbour-studio

Print the same link as a QR code from your dashboard — Dashboard → Share → QR — for reception, the window, and business cards.

02

Embedded widget — one line of code

Drops the full booking card (the one on our homepage) into your page, styled to blend in. Paste this where you want the card to appear:

<script src="https://calendar.fish/embed.js"
        data-business="harbour-studio"></script>

Optional attributes:

ATTRIBUTEWHAT IT DOES

data-businessYour handle. Required.

data-langWidget language: en es pt fr de af. Defaults to the visitor's browser.

data-accentButton colour as a hex value, to match your site. Defaults to lagoon.

data-servicePre-select one service by name, e.g. consultation. Defaults to showing all services.

Works on WordPress, Wix, Squarespace, Shopify and plain HTML — anywhere that accepts an embed/HTML block. The widget is ~14 kB and loads after your page does.

03

Book button — opens as a popup

Prefer your own button? Add data-calendarfish to any link and the booking card opens in a popup over your page instead of navigating away:

<script src="https://calendar.fish/embed.js" defer></script>

<a href="https://calendar.fish/harbour-studio" data-calendarfish>
  Book an appointment
</a>

The href stays a normal link, so it still works if the script hasn't loaded — no dead buttons.

04

WhatsApp link — bookings in chat

Once your WhatsApp number is connected (Dashboard → WhatsApp → Connect), this link opens a chat with your practice or salon, pre-filled and ready to book. Use it as your "Book on WhatsApp" button:

https://calendar.fish/harbour-studio/wa

calendar.fish answers with live availability, books the appointment, and sends the confirmation and reminders in the same chat. You can join any conversation yourself at any time.

Building something custom?

There's a simple REST API and webhooks for new, changed, and cancelled bookings — enough to sync your practice software or a spreadsheet. Grab a key from Dashboard → API.
