Link a WhatsApp Business number through Meta's Cloud API, save the IDs and tokens in Frosvo, verify the callback, and answer WhatsApp customers from the shared inbox.

WhatsApp is where many customers already are. Frosvo connects through Meta's WhatsApp Cloud API.

## What you need

- A Meta business account and a Meta app.
- A WhatsApp business phone number connected to that app.
- Owner or **Channels** permission in Frosvo.

## Step 1: prepare Meta

1. Create a Meta business app and connect a WhatsApp business number.
2. Grant messaging permissions and create a **system user** with an access token.
3. Note the **Phone number ID**, the **Business account ID** and your **App secret**.
4. Choose a **Webhook verify token**: any long private value.

## Step 2: save in Frosvo

1. Go to **Channels**, click **Add channel** and choose **WhatsApp**.
2. Pick the website and name the connection.
3. Paste the Phone number ID, Business account ID, Access token, App secret and Webhook verify token.
4. Click **Save and check**.

## Step 3: connect the callback

When the account check passes, the **Steps to turn it on** panel shows the address to add, with a **Copy** button. In your Meta app, set it as the WhatsApp webhook with your verify token, then subscribe to **messages** and delivery receipts. Meta signs each message with your app secret, and Frosvo checks it. Then tick **I have added this address in Meta**.

## Step 4: enable

Make sure **Account checked** has a tick, then click **Turn on messaging**. Send a WhatsApp message to your number and confirm it appears in the inbox, then reply.

## The reply window and templates

WhatsApp lets you answer freely only within a window after the customer's latest message. To start a conversation or reply after the window closes you must use a **template** that Meta has approved. Approve templates before you need them. Frosvo keeps its own template list for the channel.

## Good practice

- Keep answers short; WhatsApp is a phone chat.
- Use [shared replies](/docs/saved-replies-and-macros) for common questions.
- Watch the delivery status of each message in **Channels**.

If connecting fails, see [troubleshooting](/docs/troubleshooting). Other Meta channels: [Messenger](/docs/messenger-setup) and [Instagram](/docs/instagram-setup). All channels are listed in the [channels overview](/docs/channels).

## Common questions

### Why can't I start a conversation with a customer?

WhatsApp only allows free-form replies within a reply window after the customer writes. Outside it you need an approved template message.

### Which values do I need from Meta?

The phone number ID, the business account ID, an access token from a system user, your app secret, and a verify token that you choose.

### Can I use the number in the normal WhatsApp app too?

A number registered with the Cloud API is managed through the API. Plan the number accordingly, and check Meta's rules for your number.

### Where do I find the official steps?

In Meta's WhatsApp Cloud API documentation, linked from the channel's setup panel.
