### Introduction

The **Twilio SMS Integration** in Wazzap allows you to send SMS messages as a fallback option when WhatsApp is not available for a given contact. This is especially useful in cases where the recipient does not have WhatsApp, ensuring message delivery through SMS.

This integration only supports **sending **[SMS](docId\:RXMI_9_8VhdSfk2Yhv5nM)** with a command**, not receiving. If inbound SMS is required, it must be configured directly with Twilio or through third-party automation platforms like Zapier, Pabbly, or n8n.

### How it works

1. Wazzap connects to your Twilio account via **Account SID, Auth Token, and Twilio Number**.
2. When WhatsApp is unavailable for a specific phone number, the system can automatically send the message through SMS if the option is enabled.
3. Outbound SMS will be delivered using your Twilio number by using the command [SMS](docId\:RXMI_9_8VhdSfk2Yhv5nM) .
4. Inbound SMS is **not** supported in this integration; to capture replies you must configure Twilio directly (for example, using a Zapier trigger “New Incoming Message Received”) and route those into your CRM.

### Setup in Wazzap

1. Create a Twilio account here:
   [https://www.twilio.com/referral/uxYKiH](https://www.twilio.com/referral/uxYKiH)
2. Once registered, log into the **Twilio Console** and retrieve:
   - **Account SID**
   - **Auth Token**
   - **Twilio Number**
3. In Wazzap, navigate to **General Settings > SMS**.
4. Enter the **Twilio SID**, **Twilio Token**, and **Twilio Number** into the fields.
5. (Optional) Enable the checkbox: **If WhatsApp does not exist, send SMS**.
6. Click **Save SMS**.
7. Activate the SMS feature.

### Alternative via Highlevel (LeadConnector)

1. If your account is managed under **GoHighLevel (LeadConnector SMS provider)**, you can request Twilio credentials directly from Highlevel support.
2. These keys can be placed into the same fields in Wazzap.
3. Once saved, the integration will allow outbound SMS fallback through LeadConnector’s Twilio infrastructure.

### If WhatsApp does not exist, send SMS. 

1. A customer’s phone number is not associated with WhatsApp.
2. Wazzap attempts to deliver the message via WhatsApp → fails.
3. The system checks the option **If WhatsApp does not exist, send SMS**.
4. The message is sent via Twilio SMS instead, using the registered Twilio Number.

### Result

1. Messages are delivered as SMS automatically if WhatsApp is not available.
2. Outbound communication is guaranteed, avoiding lost interactions.
3. Inbound replies are **not captured** unless configured separately in Twilio.

### ⚠️ Important Notes

1. This integration supports **outbound SMS only**.
2. To receive inbound SMS, configure a direct integration with Twilio (Zapier, Pabbly, n8n, or custom API).
3. Ensure that the **Twilio Number** is SMS-capable before configuration.
4. If using Highlevel (LeadConnector), verify with support that your account has SMS enabled and obtain the correct keys.
