"Since using WhatsApp reminders with Callendar, we've seen a significant drop in no-shows. Highly recommend!"

– Bruno Chiappino, Casa grande Propiedades

"In Latin America, people tend not to check emails or SMS messages; instead, we pay the most attention to WhatsApp notifications. Callendar is the perfect add-on for Calendly, Google Calendar, HubSpot Meeting Scheduler or Zoom Meeting Scheduler, significantly reducing no-shows through WhatsApp reminders."

– Rocio Pla, Workforce

"I used to lose leads because they often forgot about our meetings, and no-shows were extremely frustrating. Thanks to Callendar, my day-to-day has greatly improved."

Frequently Asked Questions

This app allows you to easily schedule appointments with your WhatsApp contacts. Your invitees will receive reminders one day before and a few minutes before the meeting. Whether the meeting is in-person or online, invitees will be notified through their preferred channel: WhatsApp. Notifications include options to cancel or reschedule the appointment without leaving WhatsApp.

The WhatsApp notifications for meetings are sent from our available virtual WhatsApp numbers, most of which are provided by Meta.

Yes, you can use your own number, but please note that, according to Meta's rules, the number cannot be used simultaneously in the regular WhatsApp app. Onboarding a new number is also possible, and we provide this service in partnership with 360dialog.

No, Calendly only allows external integrations with paid versions. Currently, the minimum version required is the Standard plan.

For our Free and Standard versions, WhatsApp notifications are sent a few minutes before the meeting. In the Pro version, there are multiple notifications—one 24 hours before and another a few minutes before the meeting. The timing of both can be customized.

You will receive a WhatsApp notification when you reach your monthly limit. If you need more reminders, you'll receive instructions via WhatsApp on how to upgrade your account.

We understand. Since the WhatsApp API is a paid service, we cover the cost for the free reminders, along with server expenses, development, and more. We provide this service to thousands of happy users for free to help promote our service through word of mouth.

Absolutely. We use the official WhatsApp API as a Meta tech provider. We're also a partner of 360dialog, one of the largest Meta Business Solution Providers globally. Additionally, we are backed by our parent company, Xenio, which was founded by a team of former 360dialog employees. So yes, we are 100% official.

There are several good solutions available that enable WhatsApp reminders for Calendly meetings, Google Calendar Booking Page, HubSpot Meeting Scheduler and Zoom Meeting Scheduler through custom setups and automation. What sets our product apart is that our integration is truly plug-and-play. You don't need to worry about complicated setups—our integration is designed specifically for this purpose, making it simple and easy to implement with just a few clicks in minutes.

The number of reminders deducted per meeting depends on the version of the plan you choose. For example, if your plan includes 2 reminders for the invitee and 2 reminders for the host, each meeting will deduct 4 reminders from your monthly allowance. It's important to note that in some versions, you have the option to disable certain reminders, which can help you manage your reminder usage more efficiently.

No, HubSpot only allows Form custom fields with paid versions.

The integration connects your Calendly account or Google Calendar Booking Page or your HubSpot Meeting Scheduler account with WhatsApp to send automated reminders for scheduled events.
