To authenticate using Twilio you need to provide the following information:

* The phone number registered in your Twilio account
* Specify whether the instance is created using Test Credentials
* Your **Account SID** - This is the unique 34 character ID that represents the parent of this account.
* Your **Auth Token**

## Twilio Account SID and Auth Token

Twilio uses these two credentials, the **Account SID** and the **Auth Token**, to determine which account an API request is coming from. In that sense, the Account SID acts as a **username**, while the Auth Token acts as a **password**.

You can find the **Account SID** and **Auth Token** in the **General Settings** page. In the twilio interface select the **Account** button and select **General Settings**. Your account's Auth Token is hidden by default. Select **Show** to display the token, and **Hide** to conceal it again.

These steps were originally documented on the Twilio website on December 7, 2021. For updated information and more details
regarding Twilio visit the [Twilio documentation website](https://support.twilio.com/hc/en-us/articles/223136027-Auth-Tokens-and-How-to-Change-Them).

## Twilio Test Credentials

Should you wish to use your **Test Credentials**, you can find them by accessing **Project** \> **Project Settings** \> **API Credentials**. They are displayed next to your LIVE Credentials. More information about test credentials is available [here](https://support.twilio.com/hc/en-us/articles/223136147-Where-are-my-test-credentials-).

## Add the Twilio connection

1. Select Orchestrator from the product launcher.
2. Select a folder, and then navigate to the **Connections** tab.
3. Select **Add connection**.
4. To open the connection creation page, select the connector from the list. You can use the search bar to find the connector.
5. Enter the required credentials, and select **Connect**.

   For any secret-type field, you can select the menu next to the field and choose **Use credential asset** to reference an Orchestrator credential asset linked to an external vault instead of entering the value directly. For more information, see [Use credential assets for connections](credential-store-connections.md).

## Permissions

Connecting allows UiPath to read, write, modify, and delete Twilio data on your behalf.
