# Include sending SMS in a workflow

Just as a workflow [lets you send email notifications](https://www.tucalendi.com/en/s/ablaeufe/how-to-create-a-workflow) when a client makes a new booking with you, reminds them of the next appointment, or tells them they have rescheduled or cancelled the booking, you can also **include sending SMS in a workflow** to send **text messages** to people's cell phones.

> [!TIP]
> To send SMS you need your own **Twilio account** and must set up the [integration between TuCalendi and Twilio](https://www.tucalendi.com/en/s/integrations/integrate-twilio-with-tucalendi).

In this tutorial you'll see how to **include sending an SMS booking confirmation in a workflow**.

[We'll edit an existing workflow](https://www.tucalendi.com/en/s/ablaeufe/editing-an-existing-workflow) and add a new action that sends an **SMS confirmation**.

[Log in to TuCalendi](https://account.tucalendi.com/). Go to the **"Flows"** menu:

![Flows menu](https://www.tucalendi.com/images/content/flows/en/flow-menu-four-types.png)

Under the **"Workflows (after booking)"** option, click **"Select"** to display the workflows you have available:

![Workflow](https://www.tucalendi.com/images/content/flows/en/workflow-with-events-assigned.png)

Click **"Edit"** on the workflow you want to modify by adding the action to send a confirmation SMS.

![Editing a workflow](https://www.tucalendi.com/images/content/flows/en/editing-workflow.png)

The workflow is displayed in its current state, and you can add the new action you want.

![Workflow with three triggers](https://www.tucalendi.com/images/content/flows/en/workflow-with-three-trigger-and-actions.png)

In the trigger **"A booking has successfully made"**, we'll add a new action that sends a confirmation SMS.

Click **"Add new action"** in the corresponding trigger:

![Add new action to a triggers](https://www.tucalendi.com/images/content/flows/en/add-new-action-to-a-trigger.png)

This lets you choose what should happen:

![Add action](https://www.tucalendi.com/images/content/flows/en/add-action.png)

**Select the action** from the drop-down menu:

![Available actions](https://www.tucalendi.com/images/content/flows/en/available-actions.png)

Since you want an SMS to be sent when the customer has made the booking, select the action **"Send confirmation SMS"**:

![Add action to send confirmation SMS](https://www.tucalendi.com/images/content/flows/en/add-action-send-confirmation-sms.png)

Choose the [confirmation template](https://www.tucalendi.com/en/s/email-notifications/sms-confirmation-setting) you want to send, activate the **recipients** you want the SMS to go to, and click **"Add"**:

![Trigger with two actions](https://www.tucalendi.com/images/content/flows/en/trigger-success-booking-with-two-actions.png)

You've now added a second action to the trigger **"A booking has successfully made"**. When a customer makes a booking with you, two actions will occur:

- The **confirmation email** is sent to the customer's email address.
- A **confirmation SMS** is sent to the customer's cell phone.

When you're done with the workflow changes, click **"Save"** so that your changes to the workflow become active.
