## How to Set Up

### Configure on the Cognigy.AI Side

1. Create a Twilio Endpoint

To create a Twilio Endpoint, follow these steps:
   1. Go to **Deploy > Endpoints**.
   2. On the **Endpoints** page, click **\+ New Endpoint**.
   3. In the **New Endpoint** section, do the following:
      1. Select the **Twilio SMS** Endpoint type.
      2. Specify a unique name.
      3. Select a Flow from the list. Save changes.
      4. In the **Configuration Information** section, copy the Endpoint URL and save it for later use.

### Configure on the Twilio Side

1. Get a Phone Number
   1. Open the Twilio Console. Go to the Account Dashboard.
   2. In the left sidebar, select the **Develop** tab, then go to **Phone Numbers > Manage > Buy a Number**. Select the country and ensure the number supports SMS. Activate **SMS**. You can search for area code, for example, 211, which shows numbers available for Düsseldorf, Germany. Select the number and click **Buy**.
   3. Some phone numbers require you to validate that your company operates in the same city or region. This approach is common for German numbers. To validate the number, read the [Twilio documentation](https://help.twilio.com/) and upload proof of your company registration. The validation process can take up to 3 business days. US numbers don’t require this validation.
   4. Go to **Active Numbers**. Select the number, then go to **Voice Configuration**. From the **A call comes in** list, select **Webhook**. In the **URL** field, enter the Cognigy.AI Endpoint URL. Click **Save configuration**. To test the connection, send an SMS to your Twilio number.

2. Connect Your Twilio Number to WhatsApp
   1. Go to **Explore Products > Messaging**.
   2. Select **WhatsApp**. To connect the Twilio number to WhatsApp, your Twilio account must first be approved by WhatsApp.
