# New listings not syncing to your site

New listings stop appearing on your site even though your API key has not changed.

**Why this happens.** The most likely cause is that the connection (platform) your site is linked to has been reassigned to a different HomeRunner account. The API key on file no longer matches the account that owns the connection, and this breaks the sync.

**How to check.** Open the **HomeRunner API** settings tab and look for a 'Platform ID is not associated with the customer' error on **Webhooks Registration**.

**How to fix it.** If you see that error:

1. Update the API key to the one that belongs to the account that now owns the connection. You can find it at dashboard.homerunner.io under **avatar > Settings > API Key**.
2. Re-select the correct connection in the **API Account** dropdown.
3. Save.
4. Click **Register Webhooks**.

Still stuck? [Contact the HomeRunner team](https://homerunner.io/contact/) with your site address and what you tried, and we take it from there.
