# How to set up your Twilio account

Once the [integration between Twilio and TuCalendi](https://www.tucalendi.com/en/s/integrations/integrate-twilio-with-tucalendi) is completed, for security reasons, you must manually enter a piece of information from your **Twilio account** and give **express permission** to enable TuCalendi to send **SMS** from your Twilio account for **notifications of bookings** generated from your online calendar.

This process is very simple.

[Log in](https://account.tucalendi.com/login) to TuCalendi with your username and password. Go to the **"SMS Settings"** option in the side menu.

Click on the **"Basic"** option:

The first thing you will see is your **Twilio account SID** code. The SID is the **security code** of your Twilio account that is obtained in the integration with TuCalendi and **cannot be changed**.

The **Sender ID** allows you to set your company name or brand as ID. [Learn more about the Sender ID in the Twilio help](https://www.twilio.com/docs/glossary/what-alphanumeric-sender-id).

In the **"Sender ID"** field you must enter the **phone number provided by Twilio**, a **short number** or the **alphanumeric sender ID**, so that your customers receive the SMS associated with your name or your Twilio phone number.

You must enable the **"I confirm"** option to confirm that you allow TuCalendi to send SMS from your Twilio account.

> [!WARNING]
> NOTE: TuCalendi informs you that you will be **charged on your Twilio account for each SMS sent**. TuCalendi is not responsible for these costs and cannot be held liable for them.

By performing these actions you will be able to send SMS for **confirmation** and **reminder notifications** for events scheduled by your customers from your TuCalendi online calendar.

You can now [set up the SMS confirmation](https://www.tucalendi.com/en/s/email-notifications/sms-confirmation-setting) and [the SMS reminder](https://www.tucalendi.com/en/s/email-notifications/sms-reminder-setting) that your customers will receive.
