# Overview

This page describes the process for a multi-sync tags solution.

## Standard Multi-sync Tag

To sync with multiple third-party data providers and exchanges, Buyer Cloud offers a multi-sync iframe tag.

#### Example of the iframe tag:

##### **html**

```
<iframe src="https://match.prod.bidr.io/cookie-msync?buzz_key=<your_buzz_key>" height="0" width="0" ... />
```

This tag calls the **multi-sync endpoint** (a buyer-initiated sync) and synchronizes the user with our partner data providers.

- **First-time encounters**: When a user encounters the tag for the first time, it syncs with 10 partners.
- **Subsequent encounters**: Each time the same user encounters the tag again, it syncs with an additional 10 partners, and so on.

## Custom Multi-sync Tag

For customers who want to prioritize certain sync partners and improve match rates with specific data providers or exchanges, Buyer Cloud offers a custom multi-sync tag.

The setup for the custom tag is the same as the standard tag on the page. However, the multi-sync endpoint can be configured by your account manager to specify:

- Which data partners to sync with
- The order in which the partners are synced

If you wish to implement a custom multi-sync tag, please reach out to your account representative or contact support.

> ℹ️ - Custom configurations on your pixel will override the default Buyer Cloud sync settings.
> ℹ️ - Any new partners added to Buyer Cloud's default sync settings will **not** be automatically included in your custom list.
