**You can use the Open URL action to create buttons that trigger a phone call, send an email, or send an SMS from a mobile device.**

> **Warning**
>
> Note that although the tool allows you to add links `tel:`, `mailto:`, and
> `sms:`, they do not work consistently across all devices and browsers. Some
> devices do not allow phone calls or SMS, and others do not handle links
> reliably.

> **Info**
>
> There is an alternative method that involves the use of webhooks (Zapier,
> Make). This technique allows integrating PandaSuite with a variety of external
> services, like
> [Twilio](https://docs.pandasuite.com/essentials/integrations/send-sms-via-twilio/),
> [Gmail](https://docs.pandasuite.com/essentials/components/authentication/)... By
> setting up a webhook in PandaSuite, you can trigger an event that sends
> information to these external services as soon as a specific action is
> performed in your PandaSuite app or project.

## Triggering a phone call

To trigger a phone call:

- Add an **Open URL** action
- In **URL**, enter `tel:` followed by the phone number.
- You can use [data binding](https://docs.pandasuite.com/essentials/data/data-binding/) to dynamically populate the phone number

When users click on this button, it automatically opens the default phone application on their device with the number pre-filled.

Remember to include the country code prefix to ensure the call is directed to the correct phone number.

## Sending an email

To send an email:

- Add an **Open URL** action

```
