Use a Twilio number or Messaging Service to send and receive text messages from the shared inbox. Save the Account SID, number and Auth Token, then point Twilio at Frosvo's callback.

Some customers prefer a text. With a Twilio number you can answer them from the inbox.

## What you need

- A Twilio account.
- An SMS-capable number, bought or ported in Twilio, or a Messaging Service.
- Owner or **Channels** permission in Frosvo.

## Step 1: collect your Twilio details

1. Buy or port an SMS-capable number in Twilio, or create a Messaging Service.
2. From the Twilio console copy your **Account SID** and **Auth Token**.

## Step 2: save in Frosvo

1. Go to **Channels**, click **Add channel** and choose **SMS**.
2. Pick the website and name the connection.
3. Paste the **Twilio Account SID**, the **Sending number** (or Messaging Service SID) and the **Twilio Auth Token**.
4. Click **Save and check**.

## Step 3: tell Twilio where to send texts

When the account check passes, the **Steps to turn it on** panel shows the address to add, with a **Copy** button. In Twilio open the number, find **A message comes in** and set it to that URL with the method **HTTP POST**. Twilio signs each request with your Auth Token, and Frosvo checks the signature. Then tick **I have added this address in Twilio**.

## Step 4: check and enable

Make sure **Account checked** has a tick, then click **Turn on messaging**. Text your number from a phone and confirm the message appears in the **Inbox**. Reply and check it arrives as a text.

## Things to keep in mind

- Texts are short. Keep answers brief.
- Carriers have their own rules about business texting. Check Twilio's requirements for your country before sending marketing messages.
- Each text can cost money on your Twilio account.

## Troubleshooting

If nothing arrives, check the webhook in Twilio and the status shown on the **Channels** page. The [troubleshooting guide](/docs/troubleshooting) lists common causes. For other channels see [WhatsApp](/docs/whatsapp-setup) and the [channels overview](/docs/channels).

## Common questions

**Can I use a Messaging Service instead of a number?** Yes. Enter its SID, which starts with MG, as the sending number.

**What if replies stop after I change the number?** Update the webhook on the new number and open the channel with **Edit** and click **Save and check**.

## Common questions

### What do I enter as the sending number?

Your number in international format such as +15551234567, or a Twilio Messaging Service SID that starts with MG.

### Can customers send pictures?

Yes. Text messages and MMS through your Twilio number are supported.

### Why do I need to set a webhook in Twilio?

Twilio sends incoming texts to that address. Without it, messages never reach Frosvo.

### Where is the Account SID?

On the front page of the Twilio console. It starts with AC followed by 32 characters.
