How to Use Twilio for Appointment SMS Reminders
Now, let’s move to the main part of this tutorial. As you are aware, we will be utilizing the Bookster plugin with their new Twilio add-on. First, we will install and activate the Twilio add-on on the website.

Now, open the Bookster settings and check the integrations tab. There, you will see the SMS option.

You need to complete the integration now.

Enter details like:
- Account SID
- Auth token
- Sender phone number
All these details can be found under your Twilio account. Once you have pasted the credentials, save the settings. Next, move to the notifications tab.

There, you can see the main appointment reminder types:

- New pending booking – customer
- Approved booking – customer
- Approved appointment – agent
- Canceled appointment – agent
- Resend appointment – customer
- Resend appointment – agent
To send reminders, you need to tweak the resend appointment template. You can send it to both the customer and the agent so they won’t miss it.
Once you have clicked the template, you can edit the content.

You can also check the placeholders tab to add custom content to your SMS reminder.

Tweak the content as you like and save the changes.
From now on, whenever someone books an appointment, they will get an SMS reminder on their registered mobile number.

- Use a friendly tone: strike a balance between professionalism and approachability to maintain a positive customer experience.
