# Answer eBay buyer questions from the Frosvo inbox

Connect your eBay seller account with a production keyset and refresh token, and buyers' questions about your items arrive as conversations you answer from the shared inbox.

Buyers ask questions about items before and after they buy. Answer them quickly and in one place.

## What you need

- An eBay seller account.
- A developer account at **developer.ebay.com**.
- Owner or **Channels** permission in Frosvo.

## Steps

1. At developer.ebay.com create a **production keyset** and copy the **App ID (Client ID)** and **Cert ID (Client Secret)**.
2. Under **User Tokens**, choose **Get a Token from eBay via Your Application** (OAuth), sign in as the seller and copy the **user refresh token**.
3. In Frosvo go to **Channels**, click **Add channel** and choose **eBay**.
4. Pick the website, name the connection and paste the App ID and Cert ID. Enter your **eBay site ID** if you do not sell on eBay US.
5. Paste the **User refresh token**.
6. Click **Save and check**. When the ticks show **Saved** and **Account checked**, click **Turn on messaging**.

You do not need a callback: Frosvo asks eBay for new messages regularly.

## What to expect

Buyers' questions arrive every few minutes. Each buyer and item is its own conversation, so you always see which item is being discussed. Replies go back through eBay as plain text, up to 2000 characters.

## Keep it working

The refresh token lasts about 18 months. Put a reminder in your calendar, create a new token before it ends and paste it in Frosvo. If the token stops working, owners are alerted on the [Problems page](/docs/problems-and-alerts).

## Troubleshooting

If **Save and check** fails, make sure you used the **production** keyset and not the sandbox, and that the token belongs to the seller account. See [troubleshooting](/docs/troubleshooting). A similar review channel is [Google Play](/docs/google-play-reviews-setup). Browse all channels in the [channels overview](/docs/channels), or read about [answering in the inbox](/docs/inbox).

## Common questions

**Which eBay sites are supported?** Enter the site ID for the site you sell on. 0 is eBay US, 3 is the UK and 77 is Germany.

**Why do buyers appear as separate conversations?** Each buyer and item is its own thread, so a question about one item never mixes with another.

## Common questions

### How long does the refresh token last?

About 18 months. Make a new one before it expires and save it in Frosvo.

### How long can a reply be?

Up to 2000 characters, as plain text.

### What is the eBay site ID?

A number for the eBay site you sell on: 0 for eBay US, 3 for the UK, 77 for Germany.

### How are conversations grouped?

Each buyer and item is its own conversation.
