Calendly and WhatsApp, ready to switch on

Everyone who books a slot gets a confirmation and two reminders on WhatsApp, a reschedule or a cancellation sends an update, and no-shows are flagged to you. You paste two keys in your account and we switch it on for you.

We check both keys

Each key is checked against Calendly's and WhatsApp's own API the moment you paste it. If one doesn't pass, the screen says what to fix, and a person joins the chat if that isn't enough.
Book one test slot, then we switch it on

A minute or two. Book a slot with yourself, enter your own number and watch the confirmation arrive. A person checks the setup and switches it on, within a working day.

When Calendly or WhatsApp changes its API, we fix it within a working day. You don't get a ticket to solve.

Before you decide

Where does the phone number come from?

From your Calendly booking form. Add the phone question and make it required; that's the number we write to.

Which WhatsApp does this need?

The official WhatsApp Business API from Meta, on a number you own. The WhatsApp app on a phone has no API, so it can't be connected. If you don't have the API yet, tell us and we'll walk you through getting it.

Can I change the reminder times?

Yes. A day before and an hour before is the default. Tell us in the chat if you'd rather have, say, two hours, and we change it. Small changes like that are free.

What if somebody books without giving a phone number?

Then there is nothing to write to, and the booking still reaches your calendar as usual. Making the phone question required on the booking form is the one change worth making before switching this on.

What if the invitee replies to the message?

Their reply reaches your WhatsApp number as a normal chat, so somebody can answer it. The reminders themselves are one way, and nothing the invitee types changes the booking except the cancel button.

What if mine is a bit different?

Tell us what should go where in plain words. Small changes to the rules above are usually free; bigger ones we price within a working day and build into the same account.
