**To set up automatic appointment reminders via WhatsApp and reduce no-shows, use the Appointments module from [Papo](https://papo.global/). Connect your Google Calendar account, define reminder rules, and the platform sends automatic WhatsApp messages before each scheduled time, keeping your clients informed and your calendar full.**

With this automation, your team doesn’t need to send manual reminders. The system triggers the message at the right time, directly in the client’s WhatsApp, using your company’s official number. Setup is simple and integrates with the scheduling flow you already use, whether via AI or manually.

## How automatic reminder sending works

The logic is straightforward: whenever an appointment is created in your connected calendar, Papo automatically schedules WhatsApp reminders according to the rules you define. The message reaches the client as a normal WhatsApp notification, with no one needing to copy and paste texts.

Papo’s Appointments module includes a follow-up tool that manages these reminders. You can configure multiple triggers (for example, one day before and one hour before) and customize the content of each. If the appointment was made by Papo’s AI during a conversation, the reminders are automatically queued.

## Step by step to set up reminders

1. **Connect Google Calendar**  
   In the Appointments module, link your Google Calendar account. This integration allows Papo to read events and sync times in real time.

2. **Define reminder rules**  
   Within the same module, access the follow-up settings. Choose the desired intervals — such as 24 hours, 2 hours, or 30 minutes before the appointment — and write the message that will be sent. You can use variables such as the client’s name and the service time.

3. **Create the appointment (or let the AI create it)**  
   The appointment can be made manually by an agent or automatically by the AI during a WhatsApp conversation. In both cases, the appointment appears in Google Calendar and Papo schedules the reminders based on the configured rules.

4. **Track the sends**  
   At the scheduled time, the message is sent from the WhatsApp number connected to your Papo account. The conversation history is recorded in the inbox, allowing your team to see whether the client replied or reacted.

For more elaborate sequences — such as asking for confirmation, sending a last-minute coupon, or a satisfaction survey after the appointment — you can combine the Appointments module with **Flows** and **Synapse**. That way, the reminder becomes part of a complete relationship journey.

## Who this automation is for

- **Beauty salons, barbershops, and aesthetic clinics** that depend on scheduled times and suffer from last-minute no-shows.
- **Medical offices and health professionals** (dentists, psychologists, physiotherapists) who need to reduce absenteeism without overloading the secretary.
- **Freelance service providers** (personal trainers, photographers, consultants) who manage their own calendars and want to automate communication.
- **Any business that schedules appointments via WhatsApp** and wants to reduce the number of “no-shows” with a polite, automatic reminder.

## Frequently asked questions

### Do I necessarily need Google Calendar?
Yes. The automatic reminder integration uses Google Calendar as the source of events. If you don’t use it yet, you need to create a free Google account and connect it to Papo.

### Can I customize the text of each reminder?
Yes. In the follow-up rules, you write the message that will be sent, and you can include the client’s name, the scheduled service, and the time. It’s possible to have different texts for the 24-hour reminder and the 1-hour reminder, for example.

### Do reminders work if the client doesn’t have my number saved?
Yes. Because sending is done through the official WhatsApp API (Cloud API), the message arrives normally, even if your number isn’t in the client’s contacts.

### Can I send more than one reminder per appointment?
Yes. You can configure as many reminders as you want, each with its own lead time and message.

### What if the client reschedules or cancels?
When the event is changed or removed in Google Calendar, Papo automatically adjusts the scheduled reminders, canceling those that are no longer needed.

### Can I use Flows to create a more complex sequence?
Yes. For journeys that go beyond a simple reminder — such as asking for confirmation, sending a payment link, or a post-service survey — you can create a Flow and use Synapse to trigger it from Appointments module events.
