Connect a Facebook Page through your Meta app, save the page token and secrets in Frosvo, subscribe the callback, and reply to Messenger customers from the shared inbox.

Customers who message your Facebook Page can be answered from the same inbox as everything else.

## What you need

- A Facebook Page you manage.
- A Meta app with the Messenger product.
- Owner or **Channels** permission in Frosvo.

## Step 1: prepare Meta

1. Connect your Facebook Page to your Meta app.
2. Grant the Page messaging permissions and complete the required app review.
3. Generate a **Page access token** and note the **Page ID** and your **App secret**.
4. Choose a **Webhook verify token**.

## Step 2: save in Frosvo

1. Go to **Channels**, click **Add channel** and choose **Messenger**.
2. Pick the website, name the connection and paste the Page ID, Page access token, App secret and Webhook verify token.
3. Leave **Human agent permission approved** empty for now. Type `yes` only after Meta approves it.
4. Click **Save and check**.

## Step 3: subscribe the callback

When the account check passes, the **Steps to turn it on** panel shows the address to add, with a **Copy** button. In the Meta app set it as the webhook with your verify token and subscribe the Page to messaging events. Then tick **I have added this address in Meta**.

## Step 4: check and enable

Make sure **Account checked** has a tick, then click **Turn on messaging**. Message your Page from a personal account and confirm the conversation appears in the **Inbox**. Reply and check it arrives.

## The reply window

Messenger lets you reply only within a window after the customer writes. With the **human agent** permission approved the window extends to seven days. Plan your response times around it, and see [automation](/docs/automation) to route and track them.

## If it fails

Open the channel with **Edit** and click **Save and check** to see the message. The most common causes are an expired token, a Page not subscribed to the app, or permissions still in review. See [troubleshooting](/docs/troubleshooting).

The same Meta app can also serve [Instagram](/docs/instagram-setup) and [WhatsApp](/docs/whatsapp-setup). See the [channels overview](/docs/channels).

## Common questions

**Can I connect several Pages?** Create one connection per Page.

## Common questions

### What is the human agent permission?

A Meta permission that lets you reply up to seven days after the customer's message. Type yes in Frosvo only after Meta has approved it for your app.

### Do I need Meta's app review?

Messaging permissions need review by Meta before they work for the public. Complete it for your app.

### Why can I not message someone first?

Messenger only allows replies inside a window after the customer writes to your Page.

### Which values do I need?

The Page ID, a Page access token, your app secret, and a verify token that you choose.
